[Docket No. 97–ANE–28–AD]

RIN 2120–AA64

Airworthiness Directives; General

Electric Company (GE) GE90–76B

Model Turbofan Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to

General Electric Company (GE) GE90–

76B model turbofan engines. This

proposed AD would require reduced life

limits for certain rotating components

installed in GE90–76B engines. This

proposal is prompted by the results of

a refined life analysis performed by the

manufacturer which revealed minimum

calculated low cycle fatigue lives lower

than the published low cycle fatigue

retirement lives for certain rotating

components installed in the GE90–76B

engines. If not corrected, this condition

could result in a low cycle fatigue

failure of a rotating component and

possibly an uncontained engine failure.

DATES: Comments must be received by

November 24, 1997.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), New England

Region, Office of the Assistant Chief

Counsel, Attention: Rules Docket No.

Discussion

As part of the substantiation for the

Federal Aviation Administration’s

(FAA) certification of the GE90–92B

engine, GE submitted an analysis to the
49946 Federal Register / Vol. 62, No. 185 / Wednesday, September 24, 1997 / Proposed Rules

FAA defining the low cycle fatigue life

of GE 90 rotating components. The

analysis included an updated material

property data base and other

refinements that resulted in a reduction

of the published low cycle fatigue

retirement life limit for certain rotating

components. The FAA has determined

that this AD is necessary to mandate

reduced life limits for certain rotating

components installed in GE90–76B

engines. If not corrected, this condition

could result in a low cycle fatigue

failure of a rotating component and

possibly an uncontained engine failure.

The FAA has reviewed and approved

the technical contents of General

Electric Company GE90 Alert Service

Bulletin (ASB) No. 72–A318, dated June

27, 1997, that describes reduced life

limits for certain rotating components.

Since an unsafe condition has been

identified that is likely to exist or

develop on other products of this same

type design, the proposed AD would

require reduced life limits for certain

rotating components. The actions would

be required to be accomplished in

accordance with the ASB described

previously.

There are approximately twenty-five

engines of the affected design in the

worldwide fleet. The manufacturer has

advised the FAA that there are currently

no engines installed on aircraft of U.S.

registry that would be affected by this

proposed AD. Therefore, there is no

associated cost impact on U.S. operators

as a result of this proposed AD.

The FAA estimates that the most

representative engines would have four

of the seven life-limited-reduced

components installed. Assuming the

four components are the High Pressure

Compressor Rotor (HPCR) 2–6 spool,

HPCR stage 7 disk, HPCR CDP seal and

the Low Pressure Turbine cone shaft

and that the parts cost is proportional to

the reduction of the low cycle fatigue

retirement lives, the required parts

would cost approximately $189,123 per

engine. Based on these figures, the FAA

estimates the total cost impact of this

proposed AD would be $189,123 per

engine.

The regulations proposed herein

would not have substantial direct effects

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. Therefore,

in accordance with Executive Order

12612, it is determined that this

proposal would not have sufficient

federalism implications to warrant the

preparation of a Federalism Assessment.

For the reasons discussed above, I

certify that 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) if

promulgated, 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 copy of the draft

regulatory evaluation prepared for this

action is contained in the rules docket.

A copy of it may be obtained by

contacting the rules docket at the

The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration proposes to amend 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

adding the following new airworthiness

directive:

General Electric Company: Docket No. 97–

ANE–28–AD.

Applicability: General Electric Company

(GE) GE90–76B model turbofan engines

installed on but not limited to Boeing 777

aircraft.

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.

To prevent a low cycle fatigue failure of a

rotating component and possibly an

uncontained engine failure, accomplish the

following:

(a) Remove from service those components

listed in Table 1 of GE Alert Service Bulletin

(ASB) No. 72–A318, dated June 27, 1997, and

replace with a serviceable component, prior

to exceeding the new cyclic life limits

established in paragraph (d) of ASB No. 72–

A318, dated June 27, 1997.

Note 2: These revised component life

limits will be added to the GE90 Engine

Manual, Chapter 05–11–00, Life Limits 001

in the August 1, 1997, Revision.

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

this AD, no replacement times may be

approved for these parts.

(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 Manager, Engine

Certification Office. Operators shall submit

their requests through an appropriate FAA

Principal Maintenance Inspector, who may

add comments and then send it to the

Manager, Engine Certification Office.

Note 3: Information concerning the

existence of approved alternative methods of

compliance with this airworthiness directive,

if any, may be obtained from the Engine

Certification Office.

(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 aircraft to

a location where the requirements of this AD

can be accomplished.

Issued in Burlington, Massachusetts, on

September 18, 1997.
