Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Supplemental notice of

proposed rulemaking (NPRM);

reopening of comment period.

SUMMARY: This action revises an earlier

proposed airworthiness directive (AD),

applicable to certain Pratt & Whitney

(PW) PW2000 series turbofan engines,

that would supersede an existing

airworthiness directive (AD) by

modifying the airworthiness limitations

section of the manufacturer’s manual

and an air carrier’s approved continuous

airworthiness maintenance program to

incorporate additional inspection

requirements. This action revises the

proposed rule by adding the low

pressure compressor (LPC) hub

assembly, high pressure turbine (HPT)

1st stage disk, and HPT 2nd stage hub

to the additional inspection

requirements. The regulatory section

revises the manufacturer’s

Airworthiness Limitations Section

(ALS) of the Instructions for Continued

Airworthiness (ICA), and for air carrier

operations revises the approved

continuous airworthiness maintenance

program. The actions specified by this

proposed 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.

Discussion

A proposal to amend part 39 of the

Federal Aviation Regulations (14 CFR

part 39) to add an airworthiness

directive (AD), applicable to certain

Pratt & Whitney (PW) PW2000 series

turbofan engines, was published as a

notice of proposed rulemaking (NPRM)

in the Federal Register on November 1,

2001 (66 FR 55138). That NPRM would

have modified the airworthiness

limitations section of the manufacturer’s

manual and an air carrier’s approved

continuous airworthiness maintenance

program to incorporate additional

inspection requirements. That NPRM

was prompted by an FAA study of inservice events involving uncontained

failures of critical rotating engine parts.

That condition, if not corrected, could

result in an uncontained engine failure

and damage to the airplane.

Since the issuance of that NPRM, the

FAA has become aware that the LPC

hub assembly, HPT 1st stage disk, and

HPT 2nd stage hub were inadvertantly

omitted from the list of parts for

enhanced inspection, and must be

added. This proposal would add to that

NPRM, modification of the

airworthiness limitations section of the

manufacturer’s manual and air carrier’s

approved continuous airworthiness

maintenance program to incorporate

additional inspection requirements.

Since this change expands the scope

of the originally proposed rule, the FAA

has determined that it is necessary to

reopen the comment period to provide

additional opportunity for public

comment.

Economic Analysis

The FAA estimates that 724 engines

installed on airplanes of US registry

would be affected by this proposed AD,

that it would take approximately 20

work hours per engine to do the

proposed actions. The average labor rate

is $60 per work hour. The cost effect of

the added inspections per engine is

approximately $1,200 per year, with the

approximate total cost for the U.S. fleet

of $868,800 per year.

Regulatory Analysis

The regulations adopted herein will

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. Therefore, it is

determined that this action does not

have federalism implications under

Executive Order 13132.

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 effect, 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

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation

safety, Safety.

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:

Pratt & Whitney: Docket No. 98–ANE–61–

AD. Supersedes AD 2000–21–09,

Amendment 39–11914.

Applicability: This airworthiness directive

(AD) is applicable to Pratt & Whitney (PW)

PW2037, PW2040, PW2037M, PW2240,

PW2337, PW2043, PW2643, and PW2143,

series turbofan engines, installed on but not

limited to Boeing 757 series and Ilyushin IL–

96T series airplanes.

Note 1: This 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

already done.

To prevent critical life-limited rotating

engine part failure, which could result in an

Federal Register / Vol. 66, No. 248 / Thursday, December 27, 2001 / Proposed Rules 66821

uncontained engine failure and damage to

the airplane, do the following:

(a) Within 30 days after the effective date

of this AD, revise the manufacturer’s Time

Limits section (TLS) of the manufacturer’s

engine manual, as appropriate for PW

PW2037, PW2040, PW2037M, PW2240,

PW2337, PW2043, PW2643, and PW2143

series turbofan engines, and for air carriers

revise the approved continuous

airworthiness maintenance program, by

adding the following:

‘‘MANDATORY INSPECTIONS

(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 to either part

number level listed in the table above, 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 (e) of

this AD, and notwithstanding contrary

provisions in § 43.16 of Federal Aviation

Regulations (14 CFR 43.16), these enhanced

inspections must be performed only in

accordance with the TLS of the appropriate

PW2000 series engine manuals.

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, Engine

Certification Office (ECO). Operators must

submit their requests through an appropriate

FAA Principal Maintenance Inspector (PMI),

who may add comments and then send it to

the Manager, 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.

Special Flight Permits

(d) Special flight permits may be issued in

accordance with §§ 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 done.

(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)) of this chapter 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.

Alternatively, 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.

Airworthiness Directives; MD

Helicopters, Inc. Model 369D, 369E,

369F, and 369FF Helicopters

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) for MD Helicopters, Inc.

Model 369D, 369E, 369F, and 369FF

helicopters with a tailboom modified

according to Aerometals supplemental

type certificate (STC) SH5055NM or

SH4801NM. The AD would require an

inspection to identify the part number

(P/N) of the bolts that attach the tail

rotor gearbox to the tailboom and

replacing any bolt of inadequate grip

length with an airworthy bolt. This AD

would also require determining the

number of bolt threads protruding from

each nutplate and adding an additional

washer if more than four threads

protrude. This proposal is prompted by

the discovery that bolts of inadequate

grip length were specified to attach the

tail rotor gearbox to the tailboom. The

actions specified by the proposed AD

are intended to prevent loss of a tail

rotor gearbox due to bolts of inadequate
