14 CFR Part 39

[Docket No. 94–ANE–56]

Airworthiness Directives; Textron

Lycoming ALF502L Series 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

Textron Lycoming ALF502L series

turbofan engines. This proposal would

establish reduced retirement life limits

for stage 1 and stage 3–7 compressor

disks, and stage 2 turbine disks, and

provide a drawdown schedule for disks

already beyond the reduced retirement

life limits. This proposal is prompted by

new life analyses of these components.

The actions specified by the proposed

AD are intended to prevent disk failure,

which could result in an inflight engine

shutdown and extensive engine damage.

DATES: Comments must be received by

May 1, 1995.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), New England

Region, Office of the Assistant Chief

Counsel, Attention: Rules Docket No.

Park, Burlington, MA 01803–5299.

Comments may be inspected at this

location between 8:00 a.m. and 4:30

p.m., Monday through Friday, except

Federal holidays.

The service information referenced in

the proposed rule may be obtained from

10812 Federal Register / Vol. 60, No. 39 / Tuesday, February 28, 1995 / Proposed Rules

Discussion

Textron Lycoming conducted new life

analyses for various components in

ALF502L series turbofan engines.

Textron Lycoming has determined that

stage 1 and stage 3–7 compressor disks,

and stage 2 turbine disks require

reduced retirement life limits. No

failures have occurred in service on the

ALF502L series engines, but inspections

of these components from ALF502R

series engines have found cracks prior

to attaining current service retirement

lives. This condition, if not corrected,

could result in disk failure, which could

result in an inflight engine shutdown

and extensive engine damage.

On October 28, 1994, AlliedSignal

Inc. purchased the turbine engine

product line of Textron Lycoming, but

as of this date the anticipated name

change on the type certificate for the

ALF502L series engines has not

occurred. However, the service bulletins

(SB) issued for these engines now bear

the title, ‘‘AlliedSignal Engines.’’ The

Federal Aviation Administration (FAA)

has reviewed and approved the

technical contents of AlliedSignal

Engines SB No. ALF 502 72–0004,

Revision 12, dated November 30, 1994,

that describes reduced retirement lives

for affected components; and

AlliedSignal Engines SB No. ALF502L

72–281, dated November 30, 1994, that

describes a drawdown schedule for

disks already beyond the reduced

retirement life limits.

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

establish reduced retirement life limits

for stage 1 and stage 3–7 compressors

disks, and stage 2 turbine disks, and

provide a drawdown schedule for disks

already beyond the reduced retirement

life limits. The actions would be

required to be accomplished in

accordance with the service bulletins

described previously.

There are approximately 184 engines

of the affected design in the worldwide

fleet. The FAA estimates that 50 engines

installed on aircraft of U.S. registry

would be affected by this proposed AD,

and that the prorated reduced service

life cost based on the cost of a new disk

would be approximately $16,400 per

engine. Based on these figures, the total

cost impact of the proposed AD on U.S.

operators is estimated to be $820,000.

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

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. App. 1354(a), 1421

and 1423; 49 U.S.C. 106(g); and 14 CFR

11.89.

§ 39.13—[Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

Textron Lycoming: Docket No. 94–ANE–56.

Applicability: Textron Lycoming ALF502L,

L–2, L–2A, L–2C, and L–3 turbofan engines

installed on but not limited to Canadair

Challenger CL600 series aircraft.

Compliance: Required as indicated, unless

accomplished previously.

To prevent disk failure, which could result

in an inflight engine shutdown and extensive

engine damage, accomplish the following:

(a) Remove from service stage 1 and stage

3–7 compressor disks, and stage 2 turbine

disks, in accordance with the drawdown

schedule and procedures described in

AlliedSignal Engines Service Bulletin (SB)

No. ALF502L 72–281, dated November 30,

1994.

(b) This AD establishes new, reduced

retirement life limits for stage 1 and stage 3–

7 compressor disks, and stage 2 turbine disks,

in accordance with AlliedSignal Engines SB

No. ALF 502 72–0004, Revision 12, dated

November 30, 1994.

(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. The request should be

forwarded through an appropriate FAA

Principal Maintenance Inspector, who may

add comments and then send it to the

Manager, Engine Certification Office.

Note: Information concerning the existence

of approved alternative methods of

compliance with this airworthiness directive,

if any, may be obtained from the Engine

Certification Office.

Issued in Burlington, Massachusetts, on

February 16, 1995.

Restricting or Prohibiting Attracting

Sharks by Chum or Other Means in the

Monterey Bay National Marine

Sanctuary

AGENCY: Sanctuaries and Reserves

Division (SRD), Office of Ocean and

Coastal Resource management (OCRM),

National Ocean Service (NOS), National

Oceanic and Atmospheric

Administration (NOAA), Department of

Commerce (DOC).

ACTION: Advance notice of proposed

rulemaking; request for comments.

SUMMARY: The National Oceanic and

Atmospheric Administration’s

Sanctuaries and Reserves Division

(SRD) is considering amending the

regulations for the Monterey Bay

National Marine Sanctuary (MBNMS or

Sanctuary) to restrict or prohibit the

attracting of sharks by the use of chum

or other means in the MBNMS. This

advance notice of proposed rulemaking

(ANPR) discusses the reasons SRD is

considering restricting or prohibiting

this activity in the MBNMS. Any

restrictions or prohibitions SRD places

on attracting sharks by the use of chum

or other means would be to ensure that

Sanctuary resources or qualities would

not be adversely impacted and/or to

avoid conflict among various users of

the Sanctuary. SRD is issuing this ANPR
