Airworthiness Directives; British Aerospace Regional Aircraft 
Jetstream Model 3201 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) issued by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    The Airworthiness Limitations Section of the Aircraft 
Maintenance Manual (AMM) applicable to the British Aerospace 
Jetstream 3200 has been revised. Some lives have been amended and 
new lives introduced. Compliance with these requirements is 
necessary to maintain airworthiness.

The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by April 12, 2007.

ADDRESSES: You may send comments by any of the following methods:
    <bullet> DOT Docket Web Site: Go to  http://dms.dot.gov and follow

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This proposed AD references the MCAI and related service 
information that we considered in forming the engineering basis to 
correct the unsafe condition. The proposed AD contains text copied from 
the MCAI and for this reason might not follow our plain language 
principles.

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2006-
26284; Directorate Identifier 2006-CE-68-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for the United Kingdom, has issued AD No. G-2004-0024, Issue 
Date: September 22, 2004, European Aviation Safety Agency (EASA) 
approved on September 16, 2004, under approval number 2004-9648 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    The Airworthiness Limitations Section of the Aircraft 
Maintenance Manual (AMM) applicable to the British Aerospace 
Jetstream 3200 has been revised. Some lives have been amended and 
new lives introduced. Compliance with these requirements is 
necessary to maintain airworthiness.
    The MCAI requires:
    From the effective date of this Airworthiness Directive (AD), 
comply with the requirements of BAE Jetstream Series 3200 Aircraft 
Maintenance Manual, Chapter 05-10-05, Airworthiness Limitations 
Description and Operation Section,* Revision 14 or later EASA 
approved revision.
    * Only the structural fatigue tasks are mandated by this AD, the 
following tasks are not addressed by this AD: All the tasks recorded 
in Tables 2, 4, 5 and 8. Together

[[Page 11301]]

with the Table No 3--task 27-70-000 Gust lock system.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    British Aerospace has issued Aircraft Maintenance Manual 05-10-05 
001--AIRWORTHINESS LIMITATIONS--DESCRIPTION AND OPERATION--BAe 
Jetstream 32, dated January 11, 2006, for Recurring Mandatory 
Inspections and Maintenance Actions. The actions described in this AMM 
are intended to correct the unsafe condition identified in the MCAI.
    This version of the above-referenced document is a later EASA-
approved version than that referenced in the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the proposed AD. These 
requirements, if ultimately adopted, will take precedence over the 
actions copied from the MCAI.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 20 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the proposed 
AD (inserting the document into the Airworthiness Limitations Section 
of the Instructions for Continued Airworthiness or other FAA-approved 
maintenance document). The average labor rate is $80 per work-hour. 
Based on these figures, we estimate the cost of the proposed AD on U.S. 
operators to be $1,600, or $80 per product.
    We have no way of determining the costs associated with having to 
replace certain parts at an earlier time due to reduced life limits.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Regulations (14 CFR 43.7) may do the actions of this AD. Make an 
entry into the aircraft records showing compliance with this AD in 
accordance with section 43.9 of the Federal Aviation Regulations (14 
CFR 43.9).

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows:
    (1) The MCAI requires you to comply with a version of a 
maintenance manual that changes life limits. The FAA requires such 
changes through a change to the Airworthiness Limitations Section of 
the Instructions for Continued Airworthiness or other FAA-approved 
maintenance document, and the FAA is mandating this through this AD.
    (2) We added information in paragraph (f) that allows the owner/
operator to insert this information into the Airworthiness 
Limitations Section of the Instructions for Continued Airworthiness 
or other FAA-approved maintenance document. Without this 
information, a licensed mechanic would be required to do the action.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Staff, FAA, Small Airplane Directorate, ATTN: Taylor 
Martin, Aerospace Engineer, 901 Locust, Room 301, Kansas City, 
Missouri 64106; telephone: (816) 329-4138; fax: (816) 329-4090, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has 
approved the information collection requirements and has assigned 
OMB Control Number 2120-0056.
