PART I



|ITEM 1. | Business
|------- | --------

Mewbourne Energy Partners 06-A, L.P. (the
Registrant or the Partnership) is a limited partnership organized under the laws of the State of Delaware on November 16, 2005 (date of inception). Mewbourne Development Corporation (MD), a Delaware
Corporation, has been appointed as the Registrants managing general partner. MD has no significant equity interest in the Registrant.

A Registration
Statement was filed pursuant to the Securities Act of 1933, as amended, registering limited and general partnership interests in a series of two Delaware limited partnerships formed under Mewbourne Energy 06-07 Drilling Programs. General and limited
partnership interests were offered at $1,000 each. The maximum offering amount was $50,000,000 (50,000 interests) per partnership. The Registration Statement was declared effective by the Securities and Exchange Commission on July 11, 2006. On
September 1, 2006, the offering of limited and general partnership interests in the Registrant was closed, with interests aggregating $50,000,000 originally being sold to 1,576 subscribers of which $43,174,000 were sold to 1,342 subscribers as
general partner interests and $6,826,000 were sold to 234 subscribers as limited partner interests.

The Registrant engages primarily in oil and gas
development and production and is not involved in any other industry segment. See the selected financial data in Item 6 and the financial statements in Item 8 of this report for a summary of the Registrants revenue, income and
identifiable assets.

The sale of crude oil and natural gas produced by the Registrant will be affected by a number of factors that are beyond the
Registrants control. These factors include the price of crude oil and natural gas, the fluctuating supply of and demand for these products, competitive fuels, refining, transportation, extensive federal and state regulations governing the
production and sale of crude oil and natural gas, and other competitive conditions. It is impossible to predict with any certainty the future effect of these factors on the Registrant.

The market for crude oil is such that the Registrant anticipates it will be able to sell all the crude oil it can produce. Natural gas will be sold to local distribution companies, gas marketers and end users on the
spot market. The spot market reflects immediate sales of natural gas without long-term contractual commitments. The future market condition for natural gas cannot be predicted with any certainty, and the Registrant may experience delays in marketing
natural gas production and fluctuations in natural gas prices.

Many aspects of the Registrants activities are highly competitive including, but not
limited to, the acquisition of suitable drilling prospects and the procurement of drilling and related oil field equipment, and are subject to governmental regulation, both at Federal and state levels. The Registrants ability to compete
depends on its financial resources and on the managing general partners staff and facilities, none of which are significant in comparison with those of the oil and gas exploration, development and production industry as a whole. Federal and
state regulation of oil and gas operations generally includes drilling and spacing of wells on producing acreage, the imposition of maximum allowable production rates, the taxation of income and other items, and the protection of the environment.

The Registrant does not have any employees of its own. MD is responsible for all management functions. Mewbourne Oil Company (MOC), a wholly
owned subsidiary of Mewbourne Holdings, Inc., which is also the parent of the Registrants managing general partner, has been appointed Program Manager and is responsible for activities in accordance with a Drilling Program Agreement entered
into by the Registrant, MD and MOC. At March 31, 2009, MOC employed 208 persons, many of whom dedicated a part of their time to the conduct of the Registrants business during the period for which this report is filed.

The production of oil and gas is not considered subject to seasonal factors although the price received by the Registrant for natural gas sales will generally tend to
increase during the winter months. Order backlog is not pertinent to the Registrants business.

|ITEM 1A. | Risk Factors
|-------- | ------------

Oil and natural gas prices are volatile. A decline in
prices could adversely affect the Registrants financial position, financial results, and cash flows.

Revenues, operating results, and profitability
depend primarily upon the prices received for oil and natural gas sales. Prices also affect the amount of cash flow available for distribution. In addition, cost ceiling write-downs may be necessary in the future if prices fall significantly.

Historically, the markets for oil and natural gas have been volatile and they are likely to continue to be volatile. Wide fluctuations in oil and natural
gas prices may result from relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty and other factors that are beyond the Registrants control, including:



| |  |  | worldwide and domestic supplies of oil and natural gas;
| | - |  | -------------------------------------------------------



| |  |  | weather conditions;
| | - |  | -------------------



| |  |  | the level of consumer demand;
| | - |  | -----------------------------



| |  |  | the price and availability of alternative fuels;
| | - |  | ------------------------------------------------



| |  |  | the proximity and capacity of natural gas pipelines and other transportation facilities;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | the price and level of foreign imports;
| | - |  | ---------------------------------------



| |  |  | domestic and foreign governmental regulations and taxes;
| | - |  | --------------------------------------------------------



| |  |  | the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | political instability or armed conflict in oil-producing regions; and
| | - |  | ---------------------------------------------------------------------



| |  |  | overall domestic and global economic conditions.
| | - |  | ------------------------------------------------

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas price movements with any certainty. Declines in oil and natural gas prices would not only reduce revenue, but could
reduce the amount of oil and natural gas that can be produced economically and, as a result, could have a material adverse effect on the Registrants financial condition, results of operations and reserves. Further, oil and natural gas prices
do not necessarily move in tandem. Because approximately 88% of the Registrants reserves at December 31, 2008 were natural gas reserves, the Registrant is more affected by movements in natural gas prices.

The actual quantities and present value of proved reserves may prove to be lower than estimated.

This report contains estimates of proved reserves. These estimates are based upon various assumptions, including assumptions required by the SEC relating to oil and natural gas prices, drilling and operating expenses,
capital expenditures, taxes and availability of funds. The process of estimating oil and natural gas reserves is complex. The process involves significant decisions and assumptions in the evaluation of available geological, geophysical, engineering
and economic data for each reservoir. Therefore, these estimates are inherently imprecise.

Actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating expenses and
quantities of recoverable oil and natural gas reserves most likely will vary from these estimates. Such variations may be significant and could materially affect the estimated quantities and present value of proved reserves. In addition, the
Registrant may adjust estimates of proved reserves to reflect production history, results of exploration and development drilling, prevailing oil and natural gas prices and other factors, many of which are beyond the Registrants control. The
Registrants properties may also be susceptible to hydrocarbon drainage from production by operators on adjacent properties.

Future price declines
may result in a write-down of asset carrying values.

The Registrant utilizes the full-cost method of accounting for costs related to oil and natural gas
properties. Under this method, all such costs (for both productive and nonproductive properties) are capitalized and amortized on an aggregate basis over the estimated lives of the properties using the unit-of-production method. However, these
capitalized costs are subject to a ceiling test which limits such pooled costs to the aggregate of the present value of future net revenues attributable to proved oil and natural gas reserves discounted at 10% plus the lower of cost or market value
of unproved properties. The full-cost ceiling is evaluated at the end of each quarter using the prices for oil and natural gas at that date. A significant decline in oil and natural gas prices from current levels, or other factors, without other
mitigating circumstances, could cause a future write-down of capitalized costs and a non-cash charge against future earnings.

The Registrants
ceiling test calculations for the year ended December 31, 2008 indicated an impairment of oil and natural gas properties of approximately $9 million.

Oil and natural gas drilling and producing operations can be hazardous and may expose the Registrant to environmental liabilities.

Oil and
natural gas operations are subject to many risks, including well blowouts, cratering and explosions, pipe failure, fires, formations with abnormal pressures, uncontrollable flows of oil, natural gas, brine or well fluids, and other environmental
hazards and risks. If any of these risks occurs, the Registrant could sustain substantial losses as a result of:



| |  |  | injury or loss of life;
| | - |  | -----------------------



| |  |  | severe damage to or destruction of property, natural resources and equipment;
| | - |  | -----------------------------------------------------------------------------



| |  |  | pollution or other environmental damage;

| |  |  | regulatory investigations and administrative, civil and criminal penalties; and
| | - |  | -------------------------------------------------------------------------------

There is inherent risk of incurring significant environmental costs and liabilities in exploration and production
operations due to generation, handling, and disposal of materials, including wastes and petroleum hydrocarbons. The Registrant may incur joint and several, strict liability under applicable U.S. federal and state environmental laws in connection
with releases of petroleum hydrocarbons and wastes on, under or from leased or owned properties, some of which have been used for oil and natural gas exploration and production activities for a number of years, often by third parties not under the
Registrants control. While the Registrant maintains insurance against some, but not all, of the risks described above, the Registrants insurance may not be adequate to cover casualty losses or liabilities. Also, in the future the
Registrant may not be able to obtain insurance at premium levels that justify its purchase.

In addition, in response to studies suggesting that emissions
of certain gases may be contributing to warming of the earths atmosphere, many states are beginning to consider initiatives to track and record these gases, generally referred to as greenhouse gases, with several states having
already adopted regulatory initiatives aimed at reducing emissions of greenhouse gases. Methane, a primary component of natural gas, and carbon dioxide, a byproduct of the burning of natural gas, are included among the types of gases targeted by
greenhouse gas initiatives and laws. This movement is in its infancy but regulatory initiatives or legislation placing restrictions on emissions of methane or carbon dioxide that may be imposed in various states of the United States could adversely
affect operations of oil and gas wells and the demand for oil and gas products.

|ITEM 2. | Properties
|------- | ----------

The Registrants properties consist primarily of
interests in properties on which oil and gas wells are located. Such property interests are often subject to landowner royalties, overriding royalties and other oil and gas leasehold interests.

Fractional working interests in developmental oil and gas prospects, located primarily in the Anadarko Basin of Western Oklahoma, the Texas Panhandle, and the Permian
Basin of New Mexico and West Texas, were acquired by the Registrant, resulting in the Registrants participation in the drilling of oil and gas wells. At December 31, 2008, the Registrant owned working interests in eighty producing wells.
The Registrant participated in the drilling of wells for the years ending December 31, 2008, 2007 and 2006 as shown in the following table:

|ITEM 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

General

The Registrant was organized as a Delaware limited partnership on November 16, 2005. The offering of limited
and general partnership interests began July 11, 2006 as a part of an offering registered under the name Mewbourne Energy Partners 06-07 Drilling Programs. The offering of limited and general partner interests in the Registrant concluded
September 1, 2006, with total investor partner contributions of $50,000,000.

The Registrant was formed to engage primarily in the business of
drilling development wells, to produce and market crude oil and natural gas produced from such properties, to distribute any net proceeds from operations to the general and limited partners and to the extent necessary, acquire leases which contain
drilling prospects. The economic life of the Registrant depends on the period over which the Registrants oil and gas reserves are economically recoverable.

|Average price/mcf |  | $    | 8.14       |      | $ | 6.63      

Oil and gas revenues. As shown in the table above, total oil and gas sales rose by $5,281,255, a 29.7% increase,
for the year ended December 31, 2008 as compared to the year ended December 31, 2007.

Of this increase, $1,028,631 and $3,452,423 were due to
increases in the average prices of oil and gas sold, respectively. Average prices rose to $100.30 from $72.04 per bbl and to $8.14 from $6.63 per mcf for the year ended December 31, 2008 as compared to the year ended December 31, 2007.

Also included in this increase were $83,855 and $716,346 which resulted from increases in the volumes of oil and gas sold, respectively. The volumes sold
increased by 836 bbls and 87,997 mcf for the year ended December 31, 2008 as compared to the year ended December 31, 2007 due to additional production during the year ended December 31, 2008.

Interest income. Interest income decreased to $37,272 for the year ended December 31, 2008 from $506,960 for the year ended December 31, 2007 as cash was
utilized for the drilling and equipping of wells and distributions to partners.

Lease operations. Lease operating expense during the year ended
December 31, 2008 increased to $913,873 from $606,423 due to a greater number of wells being operated for the entire year of 2008.

Production taxes.
Production taxes during the year ended December 31, 2008 increased to $1,420,004 from $1,292,361 for the year ended December 31, 2007 due to increased revenue.

Administrative and general expenses. Administrative and general expenses increased to $422,206 in 2008 from $400,086 in 2007 due to increased administrative expenses allocable to the Partnership.

Depreciation, depletion and amortization. Depreciation, depletion and amortization was $6,069,959 in 2008, which was comparable to $6,153,763 in 2007.

Cost ceiling write-down. There were cost ceiling write-downs totaling $9,277,771 at September 30, 2008 and December 31, 2008 due to lower oil and gas prices on
those dates. There were no write-downs during 2007.

Liquidity and capital resources

Cash decreased by $2,634,160 during the year ended December 31, 2008. Cash flows from operating activities were utilized primarily for cash distributions to partners. All wells for which funds have been committed
have been drilled. Any incidental future capital expenditures incurred will be paid with current available cash and revenues generated through oil and gas sales. Revenues which, in the sole judgment of the managing general partner, are not required
to meet the Registrants obligations will be distributed to the partners at least quarterly in accordance with the Registrants Partnership Agreement.

Critical Accounting Policies

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Significant estimates inherent in the Registrants financial statements include the estimate of oil and gas reserves and future abandonment costs. Changes in oil
and gas prices and the changes in production estimates could have a significant effect on reserve estimates. The reserve estimates directly impact the computation of depreciation, depletion, and amortization, asset retirement obligation, and the
ceiling test for the Registrants oil and gas properties.

The Registrant follows the full-cost method of accounting for its oil and gas activities.
Under the full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and gas properties are capitalized. Depreciation, depletion and amortization of oil and gas properties subject to
amortization is computed on the units-of-production method based on the proved reserves underlying the oil and gas properties. Oil and gas properties are subject to a quarterly ceiling test that limits such costs to the aggregate of the present
value of future net cash flows of proved reserves and the lower of cost or fair value of unproved properties. The present value of future net cash flows has been prepared assuming year-end selling prices, year-end development and production costs
and a 10 percent annual discount rate.

All financing activities of the Registrant are reported in the financial statements. The Registrant does not engage
in any off-balance sheet financing arrangements. Additionally, the Registrant has no contractual obligations but has a financial obligation to plug and abandon non-producing properties as discussed below.

New Accounting Pronouncements

Modernization of Oil and Gas Reporting
- In January 2009, the Securities and Exchange Commission issued revisions to the oil and gas reporting disclosures, Modernization of Oil and Gas Reporting; Final Rule (the Final Rule). In addition to changing the definition
and disclosure requirements for oil and gas reserves, the Final Rule changes the requirements for determining quantities of oil and gas reserves. The Final Rule also changes certain accounting requirements under the full cost method of accounting
for oil and gas activities. The amendments are designed to modernize the requirements for the determination of oil and gas reserves, aligning them with current practices and updating them for changes in technology. The Final Rule is effective for
annual reports on Form10-K for fiscal years ending on or after December 31, 2009. The Partnership has not yet determined the impact, if any, on the financial statements.

The Hierarchy of Generally Accepted Accounting Principles - In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles (SFAS 162).
SFAS No.162 identifies the sources for accounting principles and the framework for selecting the principles to be used in preparing financial statements of nongovernmental entities that are presented in conformity with generally accepted accounting
principles in the United States. This Statement became effective in November 2008.

##### Table of Contents

Fair Value Measurements- In September 2006, the FASB issued SFAS No. 157, which defines fair value,
establishes a framework for measuring fair value, and expands disclosures about fair value measurements. Effective January 1, 2008, the Partnership adopted SFAS No. 157, which applies to other accounting pronouncements that require or
permit fair value measurements; however, it does not require any new fair value measurements.

SFAS No. 157 establishes a valuation hierarchy for
disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. All of the
Partnerships cash equivalents fall into Level 1 and consist of short-term, highly liquid investments, which have maturities of 90 days or less, including sweep investments and money market funds. The Partnership does not have any assets
or liabilities falling under Level 2 or 3.

Disclosures about Derivative Instruments and Hedging Activities - In March 2008, the Financial
Accounting Standards Board (FASB) issued Statements of Financial Accounting Standards (SFAS) SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS No. 161). SFAS
No. 161 requires entities that utilize derivative instruments to provide qualitative disclosures about their objectives and strategies for using such instruments, as well as any details of credit-risk-related contingent features contained
within derivatives. The Partnership does not utilize derivative instruments; therefore, the Partnership does not expect this pronouncement to have any impact on the Partnerships results of operations, cash flows or financial position.

Non-controlling Interests in Consolidated Financial Statements - In December 2007, the FASB issued SFAS No. 160, Noncontrolling
Interests in Consolidated Financial Statements, an amendment of Accounting Research Bulletin No. 51 (SFAS No. 160), which improves the relevance, comparability and transparency of the financial information that a
reporting entity provides in its consolidated financial statements by establishing accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. The Partnership does not own any
subsidiaries and does not expect this pronouncement to have any impact on the Partnerships results of operations, cash flows or financial position.

Business Combinations - In December 2007, FASB issued SFAS No. 141 (revised 2007), Business Combinations (SFAS No. 141R), which replaces SFAS No. 141, Business Combinations
(SFAS No. 141). SFAS 141R retains the fundamental requirements in SFAS No. 141 that the acquisition method of accounting (which SFAS No. 141 called the purchase method) be used for all business combinations. The
Partnership has no business combinations in progress or, at this time, in future plans. The Partnership does not expect this pronouncement to have any impact on the Partnerships results of operations, cash flows or financial position.

##### Table of Contents

Accounting Standard Fair Value for Financial Assets and Financial Liabilities - In February 2007, the FASB issued
SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS No. 159). SFAS No. 159 allows entities the option to measure eligible financial instruments at fair value as of
specified dates. The Partnership did not elect fair value as an alternative as provided under SFAS No. 159 for any of its financial assets and liabilities that are not currently measured at fair value.

Asset Retirement Obligations

In accordance with Statement of Financial
Accounting Standard No. 143 (FAS 143), Accounting for Asset Retirement Obligations, the Partnership has recognized an estimated liability for future plugging and abandonment costs. This statement affects the financial
accounting and reporting obligations associated with the retirement and disposal of long-lived assets, including the Partnerships oil and gas properties, and the associated asset retirement costs.

A liability for the estimated fair value of the future plugging and abandonment costs is recorded with a corresponding increase in the full cost pool at the time a new
well is drilled. Depreciation expense associated with estimated plugging and abandonment costs is recognized in accordance with the full cost methodology.

The Partnership estimates a liability for plugging and abandonment costs based on historical experience and estimated well life. The liability is discounted using the credit-adjusted risk-free rate. Revisions to the liability could occur
due to changes in well plugging and abandonment costs or well useful lives, or if federal or state regulators enact new well restoration requirements. The Partnership recognizes accretion expense in connection with the discounted liability over the
remaining life of the well.

A reconciliation of the Partnerships liability for well plugging and abandonment costs for the years ended
December 31, 2008 and December 31, 2007 is as follows:

Organization and Related Party Transactions

The Partnership was organized on November 16, 2005 in accordance with the laws of the state of Delaware. MD, a Delaware Corporation, has been appointed as the Registrants managing general partner. MD has no
significant equity interest in the Registrant. Mewbourne Oil Company (MOC) is operator of oil and gas properties owned by the Partnership. Mewbourne Holdings, Inc. is the parent of both MD and MOC. Substantially all transactions are with MD and MOC.

In the ordinary course of business, MOC will incur certain costs that will be passed on to well owners of the well for which the costs were incurred. The
Partnership will receive their portion of these costs based upon their ownership in each well incurring the costs. These costs are referred to as operator charges and are standard and customary in the oil and gas industry. Operator charges include
recovery of gas marketing costs, fixed rate overhead, supervision, pumping, and equipment furnished by the operator. Reimbursement to MOC for operator charges totaled $552,954 and $1,921,755 for the years ended December 31, 2008 and 2007,
respectively. Operator charges are billed in accordance with the Program and Partnership Agreements.

In consideration for services rendered by MD in
managing the business of the Partnership, the Partnership during each of the initial three years of the partnership pays to MD a management fee in the amount equal to 7/10s of 1% of the subscriptions by the investor partners to the
Partnership. Management fees can only be paid out of funds available for distributions. Management fees of $350,000 were allocated to the Partnership for each of the years ended December 31, 2008 and December 31, 2007. The Partnership
includes the management fee as part of the full cost pool pursuant to Rule 4-10(c)(2) of Regulation S-X.

In general, during any particular calendar year,
the total amount of administrative expenses allocated to the Partnership by MOC shall not exceed the greater of (a) 3.5% of the Partnerships gross revenue from the sale of oil and natural gas production during each year (calculated
without any deduction for operating costs or other costs and expenses) or (b) the sum of $50,000 plus .25% of the capital contributions of limited and general partners. Administrative expenses can only be paid out of funds available for
distributions. Under this arrangement, $354,190 and $449,031 were allocated to the Partnership during the years ended December 31, 2008 and 2007, respectively.

The Partnership participates in oil and gas activities through a Drilling Program Agreement (the Program). The Partnership and MD are parties to the Program Agreement. The costs and revenues of the Program
are allocated to MD and the Partnership as follows:

|ITEM 7A. | Quantitative and Qualitative Disclosures about Market Risk
|-------- | ----------------------------------------------------------

Interest Rate Risk

The Partnership Agreement allows borrowings from banks or other financial sources of up to 20% of the total capital
contributions to the Partnership without investor approval. Should the Partnership elect to borrow monies for additional development activity on Partnership properties, it will be subject to the interest rate risk inherent in borrowing activities.
Changes in interest rates could significantly affect the Partnerships results of operations and the amount of net cash flow available for partner distributions. Also, to the extent that changes in interest rates affect general economic
conditions, the Partnership will be affected by such changes.

Commodity Price Risk

The Partnership does not expect to engage in commodity futures trading or hedging activities or enter into derivative financial instrument transactions for trading or other speculative purposes. The Partnership
currently expects to sell a significant amount of its production from successful oil and gas wells on a month-to-month basis at market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas
industry, and the level of commodity prices will have a significant impact on the Partnerships results of operations. For the year ended December 31, 2008, a 10% change in the price received for natural gas production would have had an
approximate $1,931,000 impact on revenue.

Exchange Rate Risk

The Partnership currently has no income from foreign sources or operations in foreign countries that would subject it to currency exchange rate risk. The Partnership does not currently expect to purchase any prospects located outside of
either the United States or United States coastal waters in the Gulf of Mexico.

|ITEM 9A. | Controls and Procedures
|-------- | -----------------------

(a) Evaluation of Disclosure Controls and
Procedures

As of the end of the period covered by this report, MDs management conducted an evaluation, under the supervision and with the
participation of MDs principal executive officer and principal financial officer, of the Registrants disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on this evaluation,
MDs principal executive officer and principal financial officer concluded that, as of the end of the period covered by this report, the Registrants disclosure controls and procedures are effective. Notwithstanding the foregoing, a
control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Registrant to disclose material information otherwise required to be set forth in the
Registrants periodic reports.

(b) MD Managements Annual Report on Internal Control Over Financial Reporting

MDs management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules
13a-15(f). Under the supervision and with the participation of MDs management, including MDs principal executive officer and principal financial officer, MD conducted an evaluation of the effectiveness of the Partnerships internal
control over financial reporting based on the framework in Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on MDs evaluation under the framework in Internal
Control  Integrated Framework, MDs management concluded that internal control over financial reporting was effective as of December 31, 2008. This annual report does not include an attestation report of the Registrants
registered public accounting firm regarding internal control over financial reporting. Managements report was not subject to attestation by the Registrants registered public accounting firm pursuant to temporary rules of the Securities
and Exchange Commission that permit the Registrant to provide only managements report in this annual report. There have been no changes in MDs internal controls for the quarter ended December 31, 2008 or in other factors which have
materially affected, or are reasonably likely to materially affect the internal controls over financial reporting.

Report of Independent Registered Accounting Firm

To the Partners of Mewbourne Energy Partners 06-A L.P. and to the Board of Directors of Mewbourne Development Corporation Tyler, Texas

We have audited the accompanying balance sheets of Mewbourne Energy Partners 06-A L.P. as of December 31, 2008 and 2007 and the related statements of operations,
changes in partners capital and cash flows for each of the two years in the period ended December 31, 2008. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform,
an audit of its internal control over financial reporting. Our audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Mewbourne Energy
Partners 06-A L.P. at December 31, 2008 and 2007, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2008, in conformity with accounting principles generally accepted in the
United States of America.

Mewbourne Energy Partners 06-A, L.P.

NOTES TO FINANCIAL STATEMENTS



|1. | Significant Accounting Policies:
|-- | --------------------------------

Accounting for Oil and Gas Producing
Activities

Mewbourne Energy Partners 06-A, L.P., (the Registrant or the Partnership), a Delaware limited partnership engaged
primarily in oil and gas development and production in Texas, Oklahoma, and New Mexico, was organized on November 16, 2005. The offering of limited and general partnership interests began July 11, 2006 as a part of an offering registered
under the name Mewbourne Energy Partners 06-07 Drilling Programs, (the Program), and concluded September 1, 2006, with total investor contributions of $50,000,000 originally being sold to 1,576 subscribers of which $43,174,000 were
sold to 1,342 subscribers as general partner equity interests and $6,826,000 were sold to 234 subscribers as limited partner equity interests. During 2008 all general partner equity interests were converted to limited partner equity interests. The
managing general partner has no significant equity interest in the partnership.

The Programs sole business is the development and production of oil
and gas with a concentration on gas. A substantial portion of the Programs gas production is being sold regionally in the spot market. Due to the highly competitive nature of the spot market, prices are subject to seasonal and regional pricing
fluctuations. In addition, such spot market sales are generally short-term in nature and are dependent upon obtaining transportation services provided by pipelines. The prices received for the Programs oil and gas are subject to influences
such as global consumption and supply trends.

The Partnership follows the full-cost method of accounting for its oil and gas activities. Under the
full-cost method, all productive and non-productive costs incurred in the acquisition, exploration and development of oil and gas properties are capitalized. Depreciation, depletion and amortization of oil and gas properties subject to amortization
is computed on the units-of-production method based on the proved reserves underlying the oil and gas properties. At December 31, 2008 and 2007, all capitalized costs were subject to amortization. Proceeds from the sale or other disposition of
properties are credited to the full cost pool. Gains and losses are not recognized unless such adjustments would significantly alter the relationship between capitalized costs and the proved oil and gas reserves. Capitalized costs are subject to a
quarterly ceiling test that limits such costs to the aggregate of the present value of future net cash flows of proved reserves and the lower of cost or fair value of unproved properties. There were cost ceiling write-downs totaling $9,277,771 at
September 30, 2008 and December 31, 2008 due to lower oil and gas prices on those dates. There were no write-downs during 2007.

Significant
estimates inherent in the Registrants financial statements include the estimate of oil and gas reserves and future abandonment costs. Changes in oil and gas prices and the changes in production estimates could have a significant effect on
reserve estimates. The reserve estimates directly impact the computation of depreciation, depletion, and amortization, asset retirement obligation, and the ceiling test for the Registrants oil and gas properties.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from
those estimates.

New Accounting Pronouncements

Modernization of Oil and Gas Reporting - In January 2009, the Securities and Exchange Commission issued revisions to the oil and gas reporting disclosures, Modernization of Oil and Gas Reporting; Final Rule (the
Final Rule). In addition to changing the definition and disclosure requirements for oil and gas reserves, the Final Rule changes the requirements for determining quantities of oil and gas reserves. The Final Rule also changes certain
accounting requirements under the full cost method of accounting for oil and gas activities. The amendments are designed to modernize the requirements for the determination of oil and gas reserves, aligning them with current practices and updating
them for changes in technology. The Final Rule is effective for annual reports on Form10-K for fiscal years ending on or after December 31, 2009. The Partnership has not yet determined the impact, if any, on the financial statements.

The Hierarchy of Generally Accepted Accounting Principles - In May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally
Accepted Accounting Principles (SFAS 162). SFAS No.162 identifies the sources for accounting principles and the framework for selecting the principles to be used in preparing financial statements of nongovernmental entities that
are presented in conformity with generally accepted accounting principles in the United States. This Statement became effective in November 2008.

Fair
Value Measurements- In September 2006, the FASB issued SFAS No. 157, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. Effective January 1, 2008, the
Partnership adopted SFAS No. 157, which applies to other accounting pronouncements that require or permit fair value measurements; however, it does not require any new fair value measurements.

SFAS No. 157 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into
three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. All of the Partnerships cash equivalents fall into Level 1 and consist of short-term, highly liquid investments, which
have maturities of 90 days or less, including sweep investments and money market funds. The Partnership does not have any assets or liabilities falling under Level 2 or 3.

Disclosures about Derivative Instruments and Hedging Activities - In March 2008, the Financial Accounting Standards Board (FASB) issued Statements of Financial Accounting Standards
(SFAS) SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS No. 161). SFAS No. 161 requires entities that utilize derivative instruments to provide qualitative
disclosures about their objectives and strategies for using such instruments, as well as any details of credit-risk-related contingent features contained within derivatives. The Partnership does not utilize derivative instruments; therefore, the
Partnership does not expect this pronouncement to have any impact on the Partnerships results of operations, cash flows or financial position.

Non-controlling Interests in Consolidated Financial Statements - In December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements, an amendment of Accounting Research
Bulletin No. 51 (SFAS No. 160), which improves the relevance, comparability and transparency of the financial information that a reporting entity provides in its consolidated financial statements by establishing
accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. The Partnership does not own any subsidiaries and does not expect this pronouncement to have any impact on the
Partnerships results of operations, cash flows or financial position.

Business Combinations - In December 2007, FASB issued SFAS No. 141
(revised 2007), Business Combinations (SFAS No. 141R), which replaces SFAS No. 141, Business Combinations (SFAS No. 141). SFAS 141R retains the fundamental requirements in SFAS
No. 141 that the acquisition method of accounting (which SFAS No. 141 called the purchase method) be used for all business combinations. The Partnership has no business combinations in progress or, at this time, in future plans. The
Partnership does not expect this pronouncement to have any impact on the Partnerships results of operations, cash flows or financial position.

Accounting Standard Fair Value for Financial Assets and Financial Liabilities - In February 2007, the FASB issued
SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS No. 159). SFAS No. 159 allows entities the option to measure eligible financial instruments at fair value as of
specified dates. The Partnership did not elect fair value as an alternative as provided under SFAS No. 159 for any of its financial assets and liabilities that are not currently measured at fair value.

Cash and Cash Equivalents

The Partnership maintains all its cash in one
financial institution. At various times throughout the year, the cash amount may be in excess of the amount insured by the Federal Deposit Insurance Corporation.

Asset Retirement Obligations

In accordance with FAS 143, the Partnership has recognized an estimated liability for future plugging and abandonment
costs. The estimated liability is based on historical experience and estimated well life. The liability is discounted using the credit-adjusted risk-free rate. Revisions to the liability could occur due to changes in well plugging and abandonment
costs or well useful lives, or if federal or state regulators enact new well restoration requirements. The Partnership recognizes accretion expense in connection with the discounted liability over the remaining life of the well.

A reconciliation of the Partnerships liability for well plugging and abandonment costs for the years ended December 31, 2008 and December 31, 2007 is as
follows:



|                             |  |      |         |   |      |   |

Oil and Gas Sales

The Programs oil and condensate production is sold and revenue recognized at or near the Programs wells under short-term purchase contracts at prevailing prices in accordance with arrangements which are customary in the oil
industry. Sales of gas applicable to the Programs interest are recorded as revenue when the gas is metered and title transferred pursuant to the gas sales contracts covering the Programs interest in gas reserves. The Partnership uses the
sales method to recognize oil and gas revenue whereby revenue is recognized for the amount of production taken regardless of the amount for which the Partnership is entitled based on its working interest ownership. As of December 31, 2008 and
2007, no material gas imbalances between the Partnership and other working interest owners existed.

Income Taxes

The Partnership is treated as a partnership for income tax purposes and, as a result, income of the Partnership is reported on the tax returns of the partners and no
recognition is given to income taxes in the financial statements. The Partnerships financial reporting bases of its net assets exceeded the tax bases of its net assets by $19,197,355 and $31,518,740 at December 31, 2008 and 2007,
respectively.

|2. | Organization and Related Party Transactions:
|-- | --------------------------------------------

The Partnership was
organized on November 16, 2005 in accordance with the laws of the state of Delaware. MD, a Delaware Corporation, has been appointed as the Registrants managing general partner. MD has no significant equity interest in the Registrant.
Mewbourne Oil Company (MOC) is operator of oil and gas properties owned by the Partnership. Mewbourne Holdings, Inc. is the parent of both MD and MOC. Substantially all transactions are with MD and MOC.

In the ordinary course of business, MOC will incur certain costs that will be passed on to well owners of the well on which the costs were incurred. The Partnership will
be charged their portion of these costs based upon their ownership in each well incurring the costs. These costs are referred to as Operator charges and are standard and customary in the oil and gas industry. Operator charges include recovery of gas
marketing costs, fixed rate overhead, supervision, pumping, and equipment furnished by the Operator. Reimbursement to MOC for operator charges totaled $552,954 and $1,921,755 for the years ended December 31, 2008 and 2007, respectively.
Operator charges are billed in accordance with the Program and Partnership Agreements.

In consideration for services rendered by MD in managing the
business of the Partnership, the Partnership during each of the initial three years of the partnership pays to MD a management fee in the amount equal to 7/10s of 1% of the subscriptions by the investor partners to the Partnership. Management
fees can only be paid out of funds available for distributions. Management fees of $350,000 were allocated to the Partnership for each of the years ended December 31, 2008 and December 31, 2007. The Partnership includes the management fee
as part of the full cost pool pursuant to Rule 4-10(c)(2) of Regulation S-X.

In general, during any particular calendar year, the total amount of
administrative expenses allocated to the Partnership by MOC shall not exceed the greater of (a) 3.5% of the Partnerships gross revenue from the sale of oil and natural gas production during each year (calculated without any deduction for
operating costs or other costs and expenses) or (b) the sum of $50,000 plus .25% of the capital contributions of limited and general partners. Administrative expenses can only be paid out of funds available for distributions. Under this
arrangement, $354,190 and $449,031 were allocated to the Partnership during the years ended December 31, 2008 and 2007, respectively.

The Partnership
participates in oil and gas activities through a Drilling Program Agreement (the Program). The Partnership and MD are parties to the Program Agreement. The costs and revenues of the Program are allocated to MD and the Partnership as
follows:

|Costs and expenses:                                                                                    |  |             |   |  |     |  
|Organization and offering costs (1)                                                                    |  | 0           | % |  | 100 | %
|Lease acquisition costs (1)                                                                            |  | 0           | % |  | 100 | %
|Tangible and intangible drilling costs (1)                                                             |  | 100         | % |  | 0   | %
|Operating costs, reporting and legal expenses, general and administrative expenses and all other costs |  | 70          | % |  | 30  | %



|(1) | As noted above, pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which should approximate 20% of total capital costs.
To the extent that organization and offering costs and lease acquisition costs are less than 20% of total capital costs, MD is responsible for tangible drilling costs until its share of the Programs total capital costs reaches approximately
20%. The Partnerships financial statements reflect its respective proportionate interest in the Program.

Estimated Net Quantities of Proved Oil and Gas Reserves:

Reserve estimates as well as certain information regarding future production and discounted cash flows were determined by the Partnerships independent petroleum consultants and MOCs petroleum reservoir
engineers. The Partnership considers reserve estimates to be reasonable; however, due to inherent uncertainties and the limited nature of reservoir data, estimates of oil and gas reserves are imprecise and subject to change over time as additional
information becomes available.

There have been no favorable or adverse events that have caused a significant change in estimated proved reserves since
December 31, 2008 The Partnership has no long-term supply agreements or contracts with governments or authorities in which it acts as producer nor does it have any interest in oil and gas operations accounted for by the equity method. All
reserves are located onshore within the United States.
