STANDARD OPERATIONS SPECIFICATIONS - AIRCRAFT MAINTENANCE

CHAPTER 1. INTRODUCTION

1\. PURPOSE. This document prescribes, for air carrier aircraft

of 12,500 pounds or over certificated takeoff weight,

reasonable methods of determining initial overhaul time

limits and period inspection intervals for both new and used

airframes, powerplants, propellers, and appliances. Under

the provisions of Federal Aviation Regulations 121 and 127,

the FAA approves for each aircraft, \"Operations

Specifications - Aircraft Maintenance,\" which contain

maintenance intervals for airframes, powerplants,

propellers, and appliances. Such approved overhaul time

limits and maintenance intervals apply only to the aircraft

used by each individual air carrier and are not transferable

from one air carrier to another.

2\. ELIGIBILITY. Standard Operations Specifications - Aircraft

Maintenance, or Maintenance Review Board time limits, may be

applied to aircraft being placed in FAR 121, 127, and 135.2

operations.

3\. DEFINITIONS. Terms as used in this document are defined as

follows:

a\. Aircraft. An aircraft is any contrivance now known or

hereafter invented, used, or designed for navigation of

or flight in the air, including airframes, powerplants,

propellers, and appliances.

b\. Previous Operator. Previous Operator is the last

operator who utilized the aircraft prior to its sale or

lease.

c\. Seller. Seller is the same as Previous Operator.

d\. New Operator. A new operator is a person who acquires

an aircraft, through purchase or lease, for operation

in accordance with his operating certificate, and who

HAS NOT had a previously approved maintenance program

for such type aircraft.

e\. Buyer. A \"Buyer\" is a person who acquires an aircraft,

through purchase or lease, for operation in accordance

with his operating certificate, and who HAS an approved

maintenance program for such type aircraft.

f\. Approved Time Limits. Approved time limits are those

which appear on the carrier\'s approved \"Operations

Specifications - Aircraft Maintenance,\" FAA Form 1014.

(OMB 04-R0075)

g\. Maintenance Review Board. A Maintenance Review Board

is a body of FAA maintenance specialists organized to

evaluate and establish inspection and overhaul time

limits for transport aircraft intended for use in U.S.

air carrier operations.

h\. Maintenance Review Board Reports. That document

formulated by the Maintenance Review Board that

provides an acceptable initial maintenance program for

a specific aircraft or powerplant.

i\. Proration. A process by which an operator calculates

the time since overhaul on a newly acquired airframe

and its installed powerplants, propellers, and

appliances when his approved overhaul time differs from

that of the previous operator.

j\. On Condition. Items and appliances listed as \"On

Condition\" must be restricted to components on which a

determination of continued airworthiness may be made by

inspections, measurements, or tests. These \"On

Condition\" functions are to be performed within the

time limitations prescribed for the inspection or

check. Performance tolerances and wear or

deterioration limits shall be contained in the air

carrier\'s maintenance manual. If an item or appliance

cannot be maintained in a condition of continued

airworthiness by use of \"On Condition\" procedures, it

must be placed on specific time limitation control or

be controlled by an acceptable standard for determining

time limitations (e.g., hard time or condition

monitoring).

Additional criteria to be used in determining the

eligibility of an item or appliance for \"On Condition\"

are:

\(1\) Perceptibility of wear or other deterioration of

moving parts.

\(2\) Adaptability to inspection for detection of

corrosion and internal structural integrity when

such parts or areas have an appreciable effect on

continued airworthiness.

k\. Direct Inclusion. A process by which the buyer places

a newly acquired aircraft into his approved maintenance

program for that type aircraft utilizing the existing

times of the airframe, powerplants, and appliances.

4\. GENERAL.

a\. Three acceptable means currently in use for

establishing initial maintenance programs are as

follows:

\(1\) Advisory Circular 121-1A, Standard Operations

Specifications \-- Aircraft Maintenance.

\(2\) Maintenance Review Board Reports.

\* (3) Advisory Circular 120-17A, Maintenance Control by

Reliability Methods. \*

b\. Maintenance Review Board reports, which are formulated

at the time of equipment manufacture, are valid only

until such time as the limits are published in AC

121-1A. This transfer of limits from the MRB report to

AC 121-1A is accomplished only after sufficient

satisfactory service experience has been accumulated

that warrants an updating or revision of the original

MRB limits.

c\. When a non-air carrier aircraft is acquired (e.g., one

operating under FAR Part 91, the military, or foreign),

the initial time limits for the new operator will be

those set forth in the Standard Operations

Specifications - Aircraft Maintenance or the MRB

report, whichever is applicable. The time remaining to

overhaul for the new operator will be the difference

between the actual TSO and the newly approved time

limit providing the actual TSO is the lower of the two

figures.

d\. When a non-air carrier aircraft is acquired (e.g., one

operating under FAR Part 91, the military or foreign),

the initial time limits for the buyer may be

established by using either direct inclusion or

proration in accordance with the provisions of Chapter

2\. In this type of situation, if proration is to be

used, the times shown in the Standard Operations

Specifications - Aircraft Maintenance or the MRB report

(whichever is applicable to the aircraft in question)

are to be used as the seller\'s approved overhaul time

and this figure will serve as the basis for the

proration computation.

e\. In the event an air carrier aircraft is acquired by a

new operator or buyer, up to 30 hours of time may be

accumulated under FAR Part 91 without the provisions of

the above paragraph c being invoked.

f\. The times listed in AC 121-1A (as in the case of MRB

reports) are recommended starting times. They may be

reduced if an investigation of the proposed operation

indicates that lower time limits are advisable in the

interest of safety.

g\. Higher starting times may be approved providing

sufficient justification is provided to the assigned

maintenance inspector by the operator. In making this

determination, consideration shall be given to the

following:

\(1\) Type of intended operations (geographical areas of

operation).

\(2\) The operator\'s experience in handling aircraft

equal in complexity to the new equipment.

\(3\) The scope and depth of training provided for

maintenance personnel on the new aircraft.

\(4\) The competency and capability of the carrier\'s

maintenance and quality control organizations.

\(5\) The adequacy of the maintenance and inspection

programs.

\(6\) The adequacy of all facilities and equipment

required for the maintenance of the equipment

involved.

\(7\) Calendar time vs. utilization on the aircraft to

be transferred. Long periods of idle storage time

or extremely low utilization over a period of time

can and often does have an appreciable ill effect

on the integrity of an aircraft. Careful

consideration must be given to this time element

by the assigned inspector prior to putting the

aircraft on a new certificate. Acceptance checks,

which are a necessary part of the certification

procedure must take into account the effects of

calendar time and assure that the product is

airworthy.

\(8\) Industry-wide service history.

\(9\) Previous operator\'s use of a reliability program.

h\. Appliances of the same make and basic models as those

currently in use by an operator and which are installed

in a newly acquired aircraft of a different type are

eligible for approval at the operator\'s approved

overhaul time providing it can be determined that

environmental factors will not have an adverse effect

on them.

i\. For those aircraft not listed in AC 121-1A or an MRB

document, the basic principle followed by the

Administrator will be that the inspections, checks,

maintenance, or overhaul be performed at times well

within the expected or proven service life of each

component of the aircraft.

In determining what the expected or proven time

limitations of an aircraft or any of its components

might be, the Administrator will consider the following

factors:

\(1\) Geographical area or areas of operation.

\(2\) Engine operating power, procedures, etc.

\(3\) Number of landings, long haul vs. short haul.

\(4\) Maintenance organization and inspection

procedures.

\(5\) Other operators\' service experience.

\(6\) Manufacturer\'s recommendations.

\(7\) Service history.

Special reliance will be placed on service experience,

including the information obtained from tests,

inspections, or measurements that were performed while

accumulating service experience. The maintenance

program should specify the maintenance checks,

inspections, and overhauls to be performed and the

times at which they will be accomplished.

j\. An aircraft maintained in accordance with the

provisions of a reliability program may be incorporated

into another operator\'s maintenance system by direct

inclusion under the terms of the previous or present

operator\'s reliability program, if the PMI/PAI

determines that the maintenance controls established

relate realistically and responsively to operating

experience.

NOTE: It is intended that the specific needs of the

operator, in terms of operating philosophy,

recordkeeping practices, statistical and data

processing, be thoroughly evaluated prior to program

approval. Areas of program compatibility to be

considered are: (1) Adequacy of organizational

structure; (2) Suitability of data collection and

analysis system; and (3) Timeliness of corrective

action program. Additional information that may prove

useful can be found in AC 120-17A.

\* k. In the event an operator and the assigned PMI/PAI

cannot reach an agreement in the application of either

program, the assigned inspector should contact the

regional office for guidance. If further guidance is

needed the Chief, Air Carrier Airworthiness Branch,

AFS-230, Washington, D.C., should be contacted by the

regional office. \*

5\. REVISION OF TIME LIMITATIONS - GENERAL.

a\. The inspection and overhaul time limitations applicable

to airframes, powerplants, propellers, and appliances

are normally revised on the basis of service experience

unless controlled by a reliability program in

accordance with AC 120-17A.

b\. Increases in such time limitations may be made as often

as the operator can submit proper justification and

substantiation to warrant a time increase. The

justification should indicate that such increases will

not adversely affect airworthiness of the aircraft.

When the service records indicate that any component or

subcomponent consistently requires repair, adjustment,

or other maintenance because of damage, wear, or

deterioration, within the current time limitations, the

operator will be responsible for initiating corrective

action.

c\. Time limitations may be established in terms of hours

of operation, cycles, multiples of engine overhaul

periods, or multiples of inspection periods.

d\. Time limitations for components on which deterioration

is not necessarily a function of operation hours, such

as electronic units, emergency flotation equipment,

etc., may be established in terms of calendar months.

6\. AIRFRAME - REVISION OF TIME LIMITATIONS.

a\. The increases of time limitations for overhaul or major

inspections of airframes are normally based on

evaluation of all pertinent service records and/or

examination of at least one aircraft, of the model

involved, that has been operated within five percent of

the currently approved time limitation; or

b\. Any other method acceptable to the assigned principal

maintenance inspector such as industry experience,

etc., may also be used when sufficient justification

can be furnished by the operator.

c\. When a pattern or block overhaul type of maintenance

system is used, it will be permissible to reschedule

individual items in another block or pattern, if

performance and condition of the specific item warrants

such an increase.

7\. POWERPLANT AND ASSOCIATED APPLIANCES - REVISION OF TIME

LIMITATIONS.

a\. Increases in engine overhaul periods may be approved in

increments mutually agreed upon by the operator and the

assigned principal maintenance inspector. Increase in

time limitations are normally considered on the basis

of satisfactory service experience and a teardown

examination of one exhibit engine. The engine chosen

for exhibit should have operated to within five percent

of the currently approved time limitation; or

b\. Any other method acceptable to the assigned principal

maintenance inspector such as industry experience,

etc., may also be used to increase engine overhaul

periods when sufficient justification can be furnished

by the operator.

c\. Engine accessories may be operated to multiples of the

approved engine overhaul limit if it can be shown that

satisfactory service and overhaul experience justifies

the increase and will not adversely affect the

airworthiness of the component involved.

8\. APPLIANCES - REVISION OF TIME LIMITATIONS. Increases in

established times for inspection, bench test, or overhaul

periods are normally based on consideration of the following

factors: (1) geographical area or areas of operation; (2)

number of landings, long haul vs. short haul; (3)

maintenance organization and inspection procedures; (4)

manufacturers\' recommendations; and (5) service history.

When electrical/electronics appliances are maintained on an

\"on condition\" basis, special consideration should be given

to the continued airworthiness of mechanical components of

such equipment.

9\. RELIABILITY VS. HARDTIME CONVERSION. The following

procedures apply to aircraft transferred from a nonoverhaul

program (maintenance control by reliability methods) to a

program utilizing hard times.

a\. The record of last overhaul which is required by

section 121.380 will be used to determine time on units

which have been overhauled.

b\. When a record of last overhaul is not available for

units not subject to overhaul (for example, units under

reliability control), the carrier will determine TSO or

TSN on each unit by subtracting total time on aircraft

at the time of unit installation from the total time on

the aircraft at the time of change to an overhaul

program. The time on each unit so determined will be

used to determine time remaining to overhaul on the new

program.

c\. If adequate records are not available to determine TSO

or TSN, the unit involved will have to be overhauled

before further use.

10\. EMERGENCY EQUIPMENT. The inspection periods for first aid

kits, flotation equipment, evacuation slides, and other

emergency equipment should assure the continued

serviceability and immediate readiness of such equipment for

its intended emergency purposes. Major inspection periods

are established for the purpose of determining that all

components of the emergency equipment are complete and

serviceable and may be expected to remain in this condition

until the next major inspection or actual use under

emergency conditions.

11\. AVIONICS AND INSTRUMENTS. All Operations Specifications,

Aircraft Maintenance, must identify the manufacturer and

model number of the major components in ATA systems 22, 23,

24, 31, 33, 34, and 77. If the operator chooses, the major

components and required data can be listed in any other

approved manual or document provided that the manual or

document is identified in the approved Maintenance

Specifications, preferably in the General section.

12.-15. RESERVED.

CHAPTER 2. PRORATION

16\. PURPOSE. Proration is a mathematical procedure used to

determine the percent of overhaul time expended by one

operator and to establish the time remaining to overhaul for

the new operator. As new type equipment becomes available,

many air carriers acquire this new equipment and sell or

lease their older equipment to other air carriers. Since

the older equipment has accumulated a certain amount of time

in service, it is desirable to transfer this time as it

applies to an airframe and its installed powerplants,

propellers, and appliances to the buyer. This \"time in

service\" may be phased in or prorated to the approved

overhaul time of the buyer to permit further utilization of

the affected items without the need for immediate overhaul.

17\. APPLICATION.

a\. When a buyer\'s approved overhaul time limits are lower

than those of the seller, the buyer has two options:

\(1\) He (the buyer) may elect to use the proration

process.

\(2\) The buyer may elect to use direct inclusion

providing the previous operator\'s actual time

since overhaul is less than the buyer\'s approved

overhaul time limit.

b\. When the direct inclusion option is used, the

difference between the buyer\'s approved overhaul time

limit and the previous operator\'s actual time since

overhaul will determine the time remaining to overhaul

for the buyer.

c\. When the buyer\'s approved overhaul time limit is higher

than that of the seller, proration procedures should be

used to adjust the time since overhaul. However, based

upon the buyer\'s assigned PMI\'s comparison of the

buyer\'s and seller\'s maintenance program for

similarity, direct inclusion may be used if both

programs are found comparable.

18\. SCOPE AND LIMITATIONS.

a\. An operator\'s responsibility for maintaining his

aircraft in an airworthy condition is in no way

lessened by proration of the aircraft\'s time since

overhaul.

b\. All times obtained by use of the proration formula may

be rounded out to the nearest 10-hour figure.

c\. The percentage of aircraft overhaul time expended is

computed on the basis of the previous operator\'s actual

time since overhaul.

d\. When block/pattern overhaul time is to be prorated,

each block/pattern shall be treated separately, as

though a complete aircraft were being prorated. (See

Appendix 1, Figures 1 and 2.)

e\. The operator will not be permitted to change aircraft

records to reflect only the adjusted time since

overhaul. The operator will be required to maintain

adequate records showing the adjusted time since

overhaul and the actual time since overhaul.

f\. No partial proration will be acceptable. If a carrier

elects to prorate, then the airframe and all its

installed powerplants, propellers, and appliances will

also be prorated. Spare engines and propellers

acquired by the buyer at the time of sale or at a later

date with \"time in service\" may also be prorated.

g\. Aircraft components that are life-limited and

airworthiness directives may not be prorated.

h\. Amendments to \"Operations Specifications - Aircraft

Maintenance,\" which increase overhaul time limits, are

applicable to all aircraft of the same type and model

operated by a carrier. Such time increases would apply

equally to aircraft operating on a prorated time basis

as well as to the others in the fleet. Aircraft

operating on prorated times will not have the time

increase prorated, but will be credited with the entire

increase.

i\. \"Operations Specifications - Aircraft Maintenance,\" and

the applicable preface page which established prorated

time limits, will be cancelled when the aircraft,

powerplants, propellers, and appliances to which they

relate are first overhauled. Thereafter, overhaul will

be accomplished in accordance with the operator\'s

approved overhaul time.

j\. For proration purposes, aircraft obtained from military

or non-air carrier civilian sources will be assigned

the Standard Operations Specifications - Aircraft

Maintenance or Maintenance Review Board Report times as

applicable to the particular aircraft.

k\. Any foreign air carrier aircraft listed in the Standard

Operations Specifications - Aircraft Maintenance or an

applicable Maintenance Review Board Report may be

phased into a U.S. air carrier\'s program, through the

proration formula, provided the U.S. operator presents

satisfactory evidence which indicates that the program

under which the aircraft was maintained is at least

equivalent to a program approved by the FAA for a

similar type of aircraft.

l\. Aircraft acquired by either a \"new operator\" or \"buyer\"

(see definitions, Chapter 1, paragraph 4) may enter

service via proration or direct inclusion. The reason

for the difference in terminology lies in the fact that

a new operator will be limited by the maximum times set

forth in the Standard Operations Specifications

\- Aircraft Maintenance (Appendix 2) or the applicable

MRB report. On the other hand, a \"buyer\" will have

previously established time limits for the particular

aircraft in question. For ease in presenting proration

sample exercises shown in Appendix 1, the terms \"new

operator\" and \"buyer\" are used interchangeably.

19\. DATA REQUIRED. The following data will be submitted to the

assigned air carrier maintenance inspector by the operator,

when he desires to apply for approval of prorated overhaul

times:

a\. All \"Operations Specifications - Aircraft Maintenance\"

containing the overhaul time limits utilized for the

particular aircraft by the previous operator. If the

Operations Specifications do not show hours, the buyer

shall submit such other specifications or documents

which will, in fact, establish the overhaul time limits

in hours. If a conversion to hours is necessary, the

computations used for the conversion will be included

(see Appendix 1, Figure 7).

b\. All \"Operations Specifications, Preface Pages\"

pertinent to the particular aircraft. This is

essential because the previous operator may have

operated the subject aircraft in accordance with a

preface page showing utilization of adjusted time since

overhaul calculated in accordance with the proration

formula.

c\. A document itemizing (for airframe, powerplants,

propellers, and appliances):

\(1\) The previous operator\'s:

\(a\) Approved overhaul time.

\(b\) Time since overhaul.

\(c\) Percent of overhaul time used.

\(2\) The buyer\'s:

\(a\) Approved overhaul time.

\(b\) Prorated time since overhaul.

\(c\) Prorated time remaining to overhaul.

(See Appendix 1, Figure 5.)

d\. When a block/pattern or similar overhaul system was

used by the previous operator, a document will be

submitted showing:

\(1\) The time since overhaul for each block or pattern

together with a list of items which are part of

the block or pattern (see Appendix 1, Figure 8).

\(2\) The time since overhaul for each individual item

on the aircraft.

e\. \"Operations Specifications - Aircraft Maintenance\" or a

\"Proration Document\" containing prorated times for each

aircraft operating on prorated times. In either of

these cases, a pertinent preface page must be prepared

and submitted.

\(1\) In the first case where the approved prorated

times are listed on \"Operations Specifications

\- Aircraft Maintenance\" pages, a preface page such

as that shown in Appendix 1, Figure 9, will be

executed.

\(2\) Where a proration document is used to list

prorated times in lieu of showing them on the

\"Operations Specifications - Aircraft Maintenance\"

pages, a document shall be prepared for each

aircraft operating on prorated times. Each

document shall be clearly identified and each

shall be made a part of the Operations

Specifications by means of a preface page such as

the example shown in Appendix 1, Figure 11.

\(3\) The information required by item 15c will provide

the supporting data for these specification pages

or documents.

The aforementioned documents are essential to the

application of the formula in establishing the adjusted

time since overhaul on each component, area, section,

etc., of the aircraft because if the proration formula

has been used by the previous operator of the aircraft

involved, the time since overhaul figures presented in

the document will not be the same as the actual hours

of time in service since the last overhaul of the

component, area, etc. The proration formula for the

buyer should be calculated, using the actual time since

overhaul figures maintained by the previous operator.

20\. PRORATION FORMULA. The simple mathematical procedure

explained below will result in a figure that will be the

\"time remaining to overhaul\" for the buyer.

KNOWN

8,000 hours \-\-- Previous operator\'s approved overhaul time

limit.

2,000 hours \-\-- Previous operator\'s time since overhaul.

STEP I

Divide the previous operator\'s TSO figure by the previous

operator\'s approved overhaul time limit (carry out to three

places). This division will result in a decimal which can

be used to represent the percentage of approved overhaul

time already used.

\_\_\_\_\_.250 \-\-- Percent of O.H. time used by

8,000/2,000.000 previous operator.

STEP II

Multiply the buyer\'s approved overhaul time limit figure by

the decimal arrived at in STEP I. This multiplication will

result in the prorated TSO to be used by the buyer.

buyer\'s approved overhaul time limit. The resultant figure

will be number of hours remaining to overhaul for the buyer.

It should be recognized that when an operator elects to transfer

an aircraft from a block/pattern system to a one-time overhaul, a

substantial amount of \"time remaining to overhaul\" must be

sacrificed.

In the example given here, the buyer\'s \"time remaining to

overhaul\" for each block/pattern is as follows:

A - 9756 C - 3756

B - 756 D - 6756

Since the buyer\'s approved overhaul time is 12,000 hours, it

follows that all the items in block/pattern \"B\" will be due for

overhaul within 756 hours. To phase the aircraft into a one-

time overhaul, all blocks would have to be overhauled at this

time.

FIGURE 3. TRANSFER OF AIRCRAFT FROM A ONE-TIME OVERHAUL TO A

BLOCK/PATTERN SYSTEM (BUYER\'S APPROVED OVERHAUL TIME

LIMIT IS HIGHER THAN THAT OF THE PREVIOUS OPERATOR)

In this process it is first necessary to find the buyer\'s

\"prorated time since overhaul\" and his prorated \"time remaining

to overhaul\" for the entire aircraft. This is accomplished by

first applying the routine proration formula as shown below.

KNOWN

12,000 hours \-\-- Previous operator\'s approved overhaul time

limit.

3,000 hours \-\-- Previous operator\'s time since overhaul.

16,000 hours \-\-- Buyer\'s approved overhaul time limit which is to

be divided into four blocks/patterns of 4,000

hours each. (Blocks/patterns A, B, C, and D)

12,000/3,000.000 previous operator.

-4,000 \-\-- Buyer\'s prorated TSO.

\-\-\-\-\--

12,000 \-\-- Buyer\'s prorated time remaining to overhaul.

In this particular example, since the buyer has elected to

transfer an aircraft from a one-time overhaul to a four

block/pattern system, he should recognize that a substantial

amount of his time remaining to overhaul will have to be

sacrificed. This is brought about by the need to overhaul the

entire aircraft prior to 12,000 hours and at the same time, phase

selected portions of it into various blocks/patterns.

EXAMPLE

The buyer, desiring to establish a four block/pattern system,

separates his maintenance program into four equal parts and

places the items so separated into either block/pattern A, B, C,

or D. Assuming the selection has been made, the blocks/patterns

would look like this:

Block/pattern A = 4,000 hours (cumulative time = 4,000 hours)

Block/pattern B = 4,000 hours (cumulative time = 8,000 hours)

Block/pattern C = 4,000 hours (cumulative time = 12,000 hours)

Block/pattern D = 4,000 hours (cumulative time = 16,000 hours)

The effect on items in each block/pattern as the result of

phasing them into a four block/pattern system would be as

follows:

BLOCK/PATTERN A

These items would have to be overhauled at 4,000 hours TSO for

the buyer.

This would result in a loss of 8,000 hours \"time remaining to

overhaul.\"

BLOCK/PATTERN B

These items would have to be overhauled at 8,000 hours TSO for

the buyer.

This would result in a loss of 4,000 hours \"time remaining to

overhaul.\"

BLOCK/PATTERN C

These items will be overhauled at 12,000 hours TSO for the buyer.

Since it was previously established through proration that this

was the buyer\'s \"time remaining to overhaul,\" no time will be

sacrificed on the items scheduled in this block/pattern.

BLOCK/PATTERN D

The items in this block/pattern will have to be overhauled at a

point at, or prior to 12,000 hours and again at 16,000 hours in

order to properly phase them into the system. The initial time

of overhaul of these particular items should be at the option of

the buyer, providing they do not exceed 12,000 hours. There are

several methods he may choose from to accomplish this initial

overhaul. Among these are:

1\. Initially O.H. all block/pattern D items in block/pattern A

2\. Initially O.H. all block/pattern D items in block/pattern B

3\. Initially O.H. all block/pattern D items in block/pattern C

4\. Initially O.H. 1/2 of all block/pattern D items in

block/pattern A

and O.H. 1/2 of all block/pattern D items in block/pattern B

5\. Initially O.H. 1/2 of all block/pattern D items in

block/pattern B

and O.H. 1/2 of all block/pattern D items in block/pattern C

6\. Initially O.H. 1/2 of all block/pattern D items in

block/pattern A

and O.H. 1/2 of all block/pattern D items in block/pattern C

7\. Initially O.H. 1/3 of all block/pattern D items in

block/pattern A

and O.H. 1/3 of all block/pattern D items in block/pattern B

and O.H. 1/3 of all block/pattern D items in block/pattern C

Because of the previously established prorated figure of 12,000

hours remaining to overhaul, the buyer stands to lose the same

total amount of time regardless of which method he chooses.

Method #7 appears to be the most practical approach, since it

would tend to spread the workload over a 12,000 hour period. The

entire block/pattern D would, of necessity, have to be overhauled

again at 16,000 hours at which time all items would be correctly

phased into their proper block/pattern. Consideration should be

given by the assigned inspectors to the extent of inspection

(overhaul) required in the case of initial overhauls that are

accomplished early solely for the purpose of phasing an aircraft

into a block/pattern system.

In the foregoing example, it can readily be seen that block A

items at the time of initial overhaul by the buyer will actually

have accumulated only 7,000 hours since previously overhauled

while block/pattern C items will have accumulated 15,000 hours.

In either case, it must be remembered that another 16,000 hours

will pass before they are overhauled again.

In this process it is first necessary to find the buyer\'s

prorated \"time since overhaul\" and prorated \"time remaining to

applying the routine proration formula as shown below:

limit.

3,000 hours \-\-- Previous operator\'s time since overhaul.

In this particular example, since the buyer has elected to

transfer an aircraft from a one-time overhaul to a four

block/pattern system, he should recognize that a substantial

amount of his time remaining to overhaul will have to be

sacrificed. This is brought about by the need to overhaul the

entire aircraft prior to the accumulation of 6,000 additional

hours and at the same time, phase selected portions of it into

various blocks/patterns.

separates his maintenance program into four equal parts and

places the item so separated into either block/pattern A, B, C,

would look like this:

Block/pattern A = 2,000 hours (cumulative time = 2,000 hours)

Block/pattern B = 2,000 hours (cumulative time = 4,000 hours)

Block/pattern C = 2,000 hours (cumulative time = 6,000 hours)

Block/pattern D = 2,000 hours (cumulative time = 8,000 hours)

The effect of items in each block/pattern as the result of

phasing them into a four block/pattern system would be as

follows:

BLOCK/PATTERN A

These items would have to be overhauled at 2,000 hours TSO for

the buyer.

This would result in a loss of 4,000 hours \"time remaining to

BLOCK/PATTERN B

These items would have to be overhauled at 4,000 hours TSO for

the buyer.

This would result in a loss of 2,000 hours \"time remaining to

BLOCK/PATTERN C

These items will be overhauled at 6,000 hours TSO for the buyer.

Since it was previously established through proration that this

was the buyer\'s \"time remaining to overhaul,\" no time will be

sacrificed on the items scheduled in this block/pattern.

6\. 2,000 + 1,000 = 3,000 hours - actual TSO on aircraft.

Operator \"X\" now desires to transfer the aircraft to operator

\"Y\". The overhaul time is to be prorated for operator \"Y\" and

his approved overhaul time is 14,000 hours.

7\. 3,000 divided by 12,000 = .250 of overhaul time used by \"X\".

8\. 14,000 hours = approved O.H. time for \"Y\".

9\. 14,000 x .250 = 3,500 hours prorated TSO for \"Y\".

10\. 14,000 - 3,500 = 10,500 hours remaining to overhaul for

operator \"Y\" at time of transfer.

NOTE: Actual TSO (Step 7) was used for purpose of proration to

operator \"Y\", not the prorated TSO.

\* The buyer of a previously prorated aircraft whose approved

overhaul time limits are identical to the previous operators may

utilize the remaining prorated time of the previous operator.

When a buyer uses the remaining prorated time, a document shall

be prepared listing the previous operator or operators\' approved

overhaul times on which the proration was based and shall be made

part of the operations specifications by means of a preface page

such as the example shown in Appendix 1, Figure 12. \*

METHOD A

Previous operator\'s overhaul time limit is 18 months: (360 +

180 = 540.

Previous operator\'s time since overhaul is 180 days.

Buyer\'s approved overhaul time limit is 2,000 hours.

COMPUTATIONS

540

.33 of 2,000 hours = 666 hours prorated time since overhaul for

buyer.

2,000 hours - 666 = 1,334 hours. Buyer\'s prorated time remaining

to overhaul.

METHOD B

Previous operator\'s overhaul time limit: 18 months or 540 days.

Previous operator\'s utilization time: 8 hours per day.

Previous operator\'s overhaul time limit in hours: (540 days x 8

hrs.) = 4,320.

Previous operator\'s time since overhaul (180 x 8 hours) = 1,440

hours.

Buyer\'s overhaul time limit is 2,000 hours.

Hydraulic System (Same as 55F) O.C. See Note \*

(61F) Cylinder Assembly, Main

Cabin Cargo Door Actuating O.C. See Note \*

NOTE:

\* The design of the main cabin cargo door installation is such

that in the normally latched and locked position, it can be

structurally compared to any fixed portion of the fuselage.

It is only when the door is actuated open on the ground

during cargo loading operations that the heaviest loads are

incurred. These loads would be greatest at the upper door

hinge and hydraulic actuating cylinder attach points. The

door seal would also be subject to damage at this time.

Thus, door utilization establishes inspection frequency.

Under these conditions, Douglas suggests the following

procedure for purposes of inspection.

\(1\) Conduct a general visual area inspection of the upper

cargo door hinge attachments, door jamb, door actuating

cylinder attachments, door seal and latching mechanism

at the scheduled \"D\" service following use of the

aircraft in cargo configuration.

\(2\) If the aircraft is operated solely in the passenger

configuration, conduct a general visual area inspection

(as above) no later than \"E\" frequency.

(62F) Cylinder Assembly, Main

Cabin Cargo Door Actuating O.C. See NOTE \*

NOTE:

\* The design of the main cabin cargo door installation is such

that in the normally latched and locked position, it can be

structurally compared to any fixed portion of the fuselage.

It is only when the door is actuated open on the ground

during cargo loading operations that the heaviest loads are

incurred. These loads would be greatest at the upper door

hinge and hydraulic actuating cylinder attach points. The

door seal would also be subject to damage at this time.

Thus, door utilization established inspection frequency.

Under these conditions, Douglas suggests the following

procedures for purposes of inspection: (1) Conduct a

general visual area inspection of the upper cargo door hinge

attachments, door jamb, door actuating cylinder attachments,

door seal and latching mechanism at the scheduled \"D\"

service following use of the aircraft in cargo

configuration. (2) If the aircraft is operated solely in

the passenger configuration, conduct a general visual area

inspection (as above) no later than \"E\" frequency.

\* NOTE: The design of the main cabin cargo door installation is

such that in the normally latched and locked position,

it can be structurally compared to any fixed portion of

the fuselage.

It is only when the door is actuated open on the ground

during cargo loading operations that the heaviest loads

are incurred. These loads would be greatest at the

upper door hinge and hydraulic actuating cylinder

attach points. The door seal would also be subject to

damage at this time.

Thus, door utilization established inspection

frequency. Under these conditions, Douglas suggests

the following procedure for purposes of inspection:

\(1\) Conduct a general visual area inspection of the

upper cargo door hinge attachments, door jamb, door

actuating cylinder attachments, door seal and latching

mechanism at the scheduled \"D\" service following use of

the aircraft in cargo configuration; (2) If the

Chapters 52 thru 57 - covered in the following pages, are

structural items and therefore do not have specific overhaul

times. These items, generally speaking, cannot be removed from

the aircraft; and even if they could, nothing could be done from

a maintenance standpoint to restore their original condition.

Therefore, the airworthiness of these items will be determined by

inspection/examinations in extensive detail. If specific times

are not cited, the items are to be considered \"On Condition\". if

the carrier elects to list structural inspection items in some

manner other than FAA-approved specifications, the document must

be referenced in the carrier\'s specifications and revision

handled in a similar manner to specifications revisions. X-ray

or other approved NDT methods may be substituted in lieu of

visual inspections where applicable.
