Airworthiness Directives; Pratt &

Whitney JT9D Series Turbofan Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment supersedes

an existing airworthiness directive (AD),

applicable to certain Pratt & Whitney

JT9D series turbofan engines, that

currently requires revisions to the

Airworthiness Limitations Section

(ALS) of the manufacturer’s Instructions

for Continued Airworthiness (ICA) to

include required enhanced inspection of

selected critical life-limited parts at

each piece-part exposure. This action

adds additional critical life-limited parts

for enhanced inspection. This

amendment is prompted by additional

focused inspection procedures for other

critical life-limited rotating engine parts

that have been developed by the

manufacturer. The actions specified by

this AD are intended to prevent critical

life-limited rotating engine part failure,

which could result in an uncontained

engine failure and damage to the

airplane.

DATES: Effective February 23, 2000.

ADDRESSES: The information referenced

in this AD may be examined at the

Federal Aviation Administration (FAA),

New England Region, Office of the

Regional Counsel, 12 New England

Executive Park, Burlington, MA.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39)

by superseding (AD) 99–08–12,

Amendment 39–11118 (64 FR 17954,

April 13, 1999), that is applicable to

Pratt & Whitney (PW) JT9D series

turbofan engine was published in the

Federal Register on August 16, 1999 (64

FR 44446). That action proposed to

require revisions to the Time Limits

section in the Engine Manual (EM) for

certain Pratt & Whitney (PW) JT9D

series turbofan engines to include

required enhanced inspection of

selected critical life-limited parts at

each piece-part exposure.

Since the issuance of that AD,

additional focused inspection

procedures for other critical life-limited

rotating engine parts have been

developed by PW.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. Due

consideration has been given to the two

comments received.

Both commenters suggest having the

same format for the two tables in the

AD. One also suggests using the term

‘‘all’’ rather than individual part

numbers to simplify recordkeeping tasks

for the operators. The FAA concurs with

their suggestions, and has combined the

two tables into one and substituted the

word ‘‘all’’ rather than using specific

part numbers. .

No comments were received on the

economic analysis contained in the

proposed rules. Based on that analysis,

the FAA has determined that the annual

per engine cost of $60 does not create

a significant economic impact on small

entities.

After careful review of the available

data, including the comments noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the changes

described previously. The FAA has

determined that these changes will

neither increase the economic burden

on any operator nor increase the scope

of the AD.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under 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. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ‘‘ADDRESSES.’’

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation

safety, Safety.

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends part 39 of the

Federal Aviation Regulations (14 CFR

part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

removing Amendment 39–11118 (63 FR

40220, April 13, 1999), and by adding

a new airworthiness directive, to read as

follows:

AD 2000–01–13 Pratt & Whitney:

Amendment 39–11511 Docket No. 98–

ANE–47–AD. Supersedes AD 99–08–12,

Amendment 39–11118.

Applicability:

Pratt & Whitney (PW) JT9D–7, –7A, –7H,

–7AH, –7F, –7J, –20, –20J, –59A, –70A, –7Q,

–7Q3, –7R4D, –7R4D1, –7R4E, –7R4E1,

engines, installed on but not limited to

Boeing 747 and 767 series, McDonnell

Douglas DC–10 series, and Airbus Industrie

A300 and A310 airplanes.

Note 1: This airworthiness directive (AD)

applies to each engine identified in the

preceding applicability provision, regardless

of whether it has been modified, altered, or

repaired in the area subject to the

requirements of this AD. For engines that

have been modified, altered, or repaired so

that the performance of the requirements of

this AD is affected, the owner/operator must

request approval for an alternative method of

compliance in accordance with paragraph (c)

of this AD. The request should include an

assessment of the effect of the modification,

alteration, or repair on the unsafe condition

addressed by this AD; and, if the unsafe

condition has not been eliminated, the

request should include specific proposed

actions to address it.

Compliance: Required as indicated, unless

accomplished previously. For all the fan

hubs and HPT disks listed in the following

tables, the focused inspections should shall

be conducted per the applicable documents.

To prevent critical life-limited rotating

engine part failure, which could result in an

uncontained engine failure and damage to

the airplane, accomplish the following:

Federal Register / Vol. 65, No. 12 / Wednesday, January 19, 2000 / Rules and Regulations 2865

(a) Within the next 35 days after the

(2) For the purposes of these mandatory

inspections, piece-part opportunity means:

(i) The part is considered completely

disassembled when done in accordance with

the disassembly instructions in the

manufacturer’s engine manual; and

(ii) The part has accumulated more than

100 cycles in service since the last piece-part

opportunity inspection, provided that the

part was not damaged or related to the cause

for its removal from the engine.’’

(b) Except as provided in paragraph (c) of

this AD, and notwithstanding contrary

provisions in section 43.16 of the Federal

Aviation Regulations (14 CFR 43.16), these

mandatory inspections shall be performed

only in accordance with the ALS of the

manufacturer’s ICA.

(c) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Engine Certification

Office (ECO). Operators shall submit their

requests through an appropriate FAA

Principal Maintenance Inspector (PMI), who

may add comments and then send it to the

ECO.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this airworthiness directive,

if any, may be obtained from the ECO.

(d) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

(e) FAA-certificated air carriers that have

an approved continuous airworthiness

maintenance program in accordance with the

record keeping requirement of § 121.369(c) of

the Federal Aviation Regulations (14 CFR

121.369(c)) must maintain records of the

mandatory inspections that result from

revising the Time Limits Section of the

Instructions for Continuous Airworthiness

(ICA) and the air carrier’s continuous

airworthiness program. Alternately,

certificated air carriers may establish an

approved system of record retention that

provides a method for preservation and

retrieval of the maintenance records that

include the inspections resulting from this

AD, and include the policy and procedures

for implementing this alternate method in the

air carrier’s maintenance manual required by

§ 121.369(c) of the Federal Aviation

Regulations (14 CFR 121.369(c)); however,

the alternate system must be accepted by the

appropriate PMI and require the maintenance

records be maintained either indefinitely or

until the work is repeated. Records of the

piece-part inspections are not required under

§ 121.380(a)(2)(vi) of the Federal Aviation

Regulations (14 CFR 121.380(a)(2)(vi)). All

other Operators must maintain the records of

mandatory inspections required by the

applicable regulations governing their

operations.

Note 3: The requirements of this AD have

been met when the engine manual changes

are made and air carriers have modified their

continuous airworthiness maintenance plans

to reflect the requirements in the Engine

Manuals.

(f) This amendment becomes effective on

February 23, 2000.

Issued in Burlington, Massachusetts, on
