Airworthiness Directives; Learjet

Model 60 Airplanes

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

certain Learjet Model 60 airplanes. This

proposal would require modification of

the aft core cowl nozzle of the engine

nacelles. This proposal is prompted by

a report that the sealant material in the

aft core cowl nozzle of the engine

nacelle was found to extend higher than

the nozzle’s forward flange, which can

allow it to interfere with the proper

operation of the emergency fuel shutoff

actuating mechanism. The actions

specified by the proposed AD are

intended to prevent physical

interference of the emergency fuel

shutoff actuating mechanism and

resultant engine shutdown.

DATES: Comments must be received by

July 8, 1996.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, ANM–103,

Attention: Rules Docket No. 95–NM–

Comments may be inspected at this

location between 9:00 a.m. and 3:00

p.m., Monday through Friday, except

Federal holidays.

The service information referenced in

the proposed rule may be obtained from

Discussion

The FAA has received a report that,

during installation of the aft core cowl

nozzle of the engine nacelle on a Learjet

Model 60 airplane, the sealant material

in the aft core cowl nozzle was found to

be improperly extended higher than the

nozzle’s forward flange. The cause has

been attributed to the apparent

improper installation of the sealant

material during production. Sealant

material in the aft core cowl nozzle that

extends too high, if not corrected, could

interfere with proper operation of the

lever of the emergency fuel shutoff

actuating mechanism. Such interference

could result in the failure of the

emergency fuel shutoff actuating

mechanism and resultant engine

shutdown.

The FAA has reviewed and approved

Learjet Service Bulletin SB 60–71–2,

dated May 12, 1995, which describes

procedures for modification of the aft

core cowl nozzle of the engine nacelles.

Among other actions, the modification

involves replacing the sealant on the aft

core cowl nozzle with a filler made from

6061 aluminum, and reidentifying the

aft core cowl nozzle. The modification

will ensure that the sealant does not

interfere with the function of the

emergency fuel shutoff actuating

mechanism.

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 modification of the aft core cowl

nozzle of the engine nacelles. The

actions would be required to be

accomplished in accordance with the

service bulletin described previously.

There are approximately 39 Learjet

Model 60 airplanes of the affected

design in the worldwide fleet. The FAA

estimates that 26 airplanes of U.S.

registry would be affected by this

proposed AD, that it would take

approximately 44 work hours per

airplane to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Required parts

would be supplied by the manufacturer

at no cost to the operators. Based on

these figures, the cost impact of the

proposed AD on U.S. operators is

estimated to be $68,640, or $2,640 per

airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the proposed requirements of this AD

action, and that no operator would

accomplish those actions in the future if

this AD were not adopted.

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
Federal Register / Vol. 61, No. 105 / Thursday, May 30, 1996 / Proposed Rules 27031

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. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

Learjet: Docket 95–NM–240–AD.

Applicability: Model 60 airplanes, as listed

in Learjet Service Bulletin SB 60–71–2, dated

May 12, 1995; certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

otherwise modified, altered, or repaired in

the area subject to the requirements of this

AD. For airplanes 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 (b) 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 the sealant material in the aft

core cowl nozzle of the engine nacelles from

interfering with the lever of the emergency

fuel shutoff actuating mechanism, which

could result in the failure of the emergency

fuel shutoff actuating mechanism and

resultant engine shutdown, accomplish the

following:

(a) Within 90 days after the effective date

of this AD, modify the aft core cowl nozzle

of the engine nacelles in accordance with

Learjet Service Bulletin SB 60–71–2, dated

May 12, 1995.

(b) 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, Wichita

Aircraft Certification Office (ACO), FAA,

Small Airplane Directorate. Operators shall

submit their requests through an appropriate

FAA Principal Maintenance Inspector, who

may add comments and then send it to the

Manager, Wichita ACO.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Wichita ACO.

(c) 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.
