Airworthiness Directives; Rolls-Royce

Corporation (Formerly Allison Engine

Company) AE 3007A and AE 3007C

Model 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

Rolls-Royce (RR) Corporation (formerly

Allison Engine Company) AE 3007A

and AE 3007C model engines with high

pressure turbine (HPT) 1st to 2nd stage

turbine spacer part number (P/N)

23058369 installed. This proposal

would require removal and replacement

of the HPT 1st to 2nd stage turbine

spacer P/N 23058369 before it reaches

its new reduced engine cycle life limit.

This proposal is prompted by the results

of a detailed component analysis that

indicates that the HPT 1st to 2nd stage

turbine spacer stresses are higher than

predicted. The actions specified by the

proposed AD are intended to prevent

HPT 1st to 2nd stage turbine spacer

failure which could result in an

uncontained engine failure and damage

to the airplane.

DATES: Comments must be received by

April 23, 2001.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), New England

Region, Office of the Regional Counsel,

Federal Register / Vol. 66, No. 36 / Thursday, February 22, 2001 / Proposed Rules 11127

Discussion

The manufacturer’s original analysis

of the HPT 1st to 2nd stage turbine

spacer P/N 23058369 low-cycle fatigue

life computed a cleared life of 20,000

cycles. When the part number was

reanalyzed for low-cycle fatigue life, it

was determined that the stress

concentration factor in the cooling slots

was incorrect and the stresses associated

with the forward cooling slots were

higher than predicted. The updated

analysis indicates that the low-cycle

fatigue life limit of P/N 23058369

should be reduced from 20,000 cycles to

9,400 cycles.

Since an unsafe condition has been

identified that is likely to exist or

develop on other RR AE 3007A and AE

3007C model engines of the same type

design, the proposed AD would require

removal and replacement of HPT 1st to

2nd stage turbine spacer P/N 23058369

before it reaches its new reduced engine

cycle life limit. This condition, if not

corrected, could result in HPT 1st to

2nd stage turbine spacer failure, which

could result in an uncontained engine

failure and damage to the airplane.

Economic Impact

There are approximately 378 engines

of the affected design in the worldwide

fleet. The FAA estimates that 300

engines installed on 150 airplanes of

U.S. registry would be affected by this

proposed AD. It will take approximately

13 work hours per engine to accomplish

the removal and replacement of the

affected HPT 1st to 2nd stage spacer.

The 13 work hours cited include

teardown and rebuilding from the

module level, but not engine removal.

Engines are rarely scheduled off-wing

solely for the purpose of replacement of

time-expired components.The average

labor rate is $60 per work hour.

Required parts will cost approximately

$10,012 per engine. Based on these

figures, the FAA estimates the total cost

impact of the proposed AD on U.S.

operators, to be $3,237,600. Because

most of the fleet field parts are below

the new value, special scheduling

should not be required.

Regulatory Impact

This proposed rule does not have

federalism implications, as defined in

Executive Order 13132, because it

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.

Accordingly, the FAA has not consulted

with state authorities prior to

publication of this proposed rule.

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

location provided under the caption

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:

Rolls-Royce Corporation: Docket No. 2000–

NE–41–AD.

Applicability: This AD is applicable to

Rolls-Royce (RR) Corporation (formerly

Allison Engine Company) AE 3007A and AE

3007C model engines with high pressure

turbine (HPT) 1st to 2nd stage turbine spacer

part number (P/N) 23058369 installed. These

engines are installed on but not limited to

Empresa Brasileira de Aeronautica S.A.

(EMBRAER) EMB–145 and Cessna 750 series

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

Compliance with this AD is required as

indicated, unless accomplished previously.

To prevent HPT 1st to 2nd stage turbine

spacer-failure, which could result in an

uncontained engine failure and damage to

the airplane, accomplish the following:

New Reduced Engine Cycle Life Limit

(a) For all RR Corporation AE 3007A and

AE 3007C model engines with HPT 1st to

2nd stage turbine spacer, P/N 23058369

installed, remove spacer before reaching the

new reduced engine cycle life limit of 9,400

cycles and replace with a serviceable part.

(b) Revise the airworthiness limitations

section of the Instruction for Continued

Airworthiness, as follows: P/N

23058369=9,400 cycles.

Alternative Methods of Compliance

(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, Chicago

Aircraft Certification Office. Operators shall

submit their request through an appropriate

FAA Principal Maintenance Inspector, who

may add comments and then send it to the

Manager, Chicago Aircraft Certification

Office (ACO).

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this airworthiness directive,

if any, may be obtained from the Chicago

ACO.

Special Flight Permits

(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.
