AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment supersedes

an emergency airworthiness directive

(AD) that was sent previously to all

known U.S. owners and operators of

CFMI CFM56–5C turbofan engines by

individual letters. That action required

within 10 days after receipt of that

emergency AD, an initial inspection of

the fuel manifold for wear or chafing;

and an initial inspection of the CJ9L

harness for correct installation, for

clamp wear and to verify a minimum

clearance between the CJ9L harness and

the fuel manifold. That action also

required repetitive inspections of the

fuel manifold, clamps, and the CJ9L

harness within every 500 hours time in

service until new configuration clamps

are installed on the harness. This

amendment requires the same

inspections, and adds inspection

requirements for the manifold, clamps,

and the CJ10L harness, and clamps on

the other side of the engine. The actions

specified in this AD are intended to

prevent fuel leakage on the hot section

or in the primary fire zone of the engine

which may result in an engine fire and

subsequent damage to the airplane.

DATES: Effective May 14, 2001. The

incorporation by reference of certain

publications listed in the rule is

approved by the Director of the Federal

Register as of May 14, 2001.

Comments for inclusion in the Rules

Docket must be received on or before

July 9, 2001.

SUPPLEMENTARY INFORMATION: On April

10, 2001, the Federal Aviation

Administration (FAA) issued emergency

airworthiness directive (AD) 2001–08–

51, applicable to CFMI CFM56–5C

turbofan engines, which requires within

10 days after the receipt of that AD, an

initial inspection of the fuel manifold

for wear or chafing; and an initial

inspection of the CJ9L harness for wear

and correct installation, for clamp wear

and to verify a minimum clearance

between the CJ9L harness and the fuel

manifold. Repetitive inspections of the

fuel manifold, clamps, and CJ9L harness

are also required within every 500 hours

time-in-service until the new

configuration clamps are installed on

the harness. That AD was prompted by

a report of a significant engine fuel leak

under the thrust reverser cowls at the

fuel manifold level on a CFMI CFM56–

5C turbofan engine that was installed on

an Airbus Industrie A340 airplane. The

leak was confirmed to be coming from

a hole in the fuel manifold pigtail. The

hole was a result of interference and

chafing between the CJ9L harness high

pressure turbine clearance control

(HPTCC) sensor lead and fuel manifold.

This was the second fuel leak event at

this location. Additional engine

inspections by the operator who

experienced the engine fuel leak

discovered two other engines exhibiting

interference of the CJ9L harness with

fuel manifold and chafing of the fuel

manifold. In addition, since the FAA

issued the emergency AD, chafing was

found on the CJ10L harness, located on

the other side of an engine from the

CJ9L harness. The investigation has

identified three causes for lack of

clearance between the HPTCC harnesses

and the fuel manifold:

(1) Incorrect routing of the CJ9L and

CJ10L harnesses,

(2) Incorrect orientation of the CJ9L

and CJ10L harness cushion clamps, and

(3) Wear of the silicone material in the

clamp which allows the harnesses to

move within the clamp. This clamp

material is used on older configuration

clamps. The later configuration uses a

metallic material.

The actions specified by this AD are

intended to prevent fuel leakage on the

hot section or in the primary fire zone

of the engine, which may result in an

engine fire and subsequent damage to

the airplane.

Since emergency AD 2001–08–51 was

issued, it has been determined that the

same unsafe condition exists at the

CJ10L HPTCC harness, located on the

opposite side of the engine from the

CJ9L harness.

Manufacturer’s Service Information

The FAA has reviewed and approved

CFMI Alert Service Bulletin (ASB) No.

CFM56–5C S/B 73–A0106, Revision 1,

dated April 19, 2001, that specifies

procedures for inspection of the fuel

23542 Federal Register / Vol. 66, No. 90 / Wednesday, May 9, 2001 / Rules and Regulations

manifold for wear or chafing, and

inspection of the CJ9L harness for wear

and correct installation, for clamp wear

and to verify a minimum clearance

between the CJ9L harness and the fuel

manifold.

Differences Between This AD and the

Manufacturer’s Service Information

CFMI ASB CFM56–5C S/B 73–A0106,

Revision 1, dated April 19, 2001,

requires only inspections of the CJ9L

HPTCC sensor harness. The FAA has

determined that the same inspections

must be performed on the CJ10L HPTCC

sensor harness, located on the opposite

side of the engine from the CJ9L

harness.

FAA’s Determination of an Unsafe

Condition and Proposed Actions

Although none of these affected

engine models are used on any airplanes

that are registered in the United States,

the possibility exists that the engine

models could be used on airplanes that

are registered in the United States in the

future. This AD is being issued to

prevent fuel leakage on the hot section

or in the primary fire zone of the engine,

which may result in an engine fire and

subsequent damage to the airplane. This

AD requires within 10 days after the

effective date of this AD, an initial

inspection of the fuel manifold for wear

or chafing; and an initial inspection of

the CJ9L and CJ10L harnesses for wear

and correct installation, for clamp wear

and to verify a minimum clearance

between the harnesses and the fuel

manifold. Repetitive inspections of the

fuel manifold, clamps, and the CJ9L and

CJ10L harnesses will be required within

every 500 hours time in service until the

new configuration clamps are installed

on the harness. The actions must be

done in accordance with the service

bulletin described previously.

Immediate Adoption of This AD

Since there are currently no domestic

operators of this engine model, notice

and opportunity for prior public

comment are unnecessary. Therefore, a

situation exists that allows the

immediate adoption of this regulation.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an opportunity

for public comment, comments are

invited on this rule. Interested persons

are invited to comment on this rule by

submitting such written data, views, or

arguments as they may desire.

Communications should identify the

Rules Docket number and be submitted

in triplicate to the address specified

under the caption ADDRESSES. All

communications received on or before

the closing date for comments will be

considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before

and after the closing date for comments,

in the Rules Docket for examination by

interested persons. A report that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.

Commenters wishing the FAA to

acknowledge receipt of their comments

submitted in response to this action

must submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 2001–NE–08–AD.’’ The

postcard will be date stamped and

returned to the commenter.

Regulatory Impact

This final 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 final rule.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and is not a ‘‘significant regulatory

action’’ under Executive Order 12866. It

has been determined further that this

action involves an emergency regulation

under DOT Regulatory Policies and

Procedures (44 FR 11034, February 26,

1979). If it is determined that this

emergency regulation otherwise would

be significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket. A copy

of it, if filed, may be obtained from the

Rules Docket at the location provided

under the caption ADDRESSES.

Small Business Regulatory Enforcement

Fairness Act

The Small Business Regulatory

Enforcement Fairness Act (SBREFA) of

1996, requires the FAA to comply with

small entity requests for information or

advice about compliance with statutes

and regulations within its jurisdiction.

Therefore, any small entity that has a

question regarding this document may

contact their local FAA official, or the

person listed under FOR FURTHER

INFORMATION CONTACT. You can find out

Background

In 1991, the FAA initiated a review of

part 105, which was originally

published in 1962 to determine if the

regulation continued to reflect current

practices and equipment used in the

industry. Among other information, the

FAA studied reports received from the

Aviation Safety Reporting System

(ASRS), the National Transportation

Safety Board (NTSB), Air Traffic

Unsatisfactory Condition Reports (UCR),

and recommendations from the Air

Traffic Procedures Advisory Committee

and the National Air Traffic Controllers

Association (NATCA). Upon completion

of the review, the FAA determined that

the regulation required revision to be

consistent with the parachute

equipment used today and current

industry practices.

An example of changes that have

taken place in the parachute industry

since the time part 105 was published

is the development of dual-harness,

dual parachute systems designed to

carry more than one person at a time. In

1983 the FAA began receiving petitions

for rulemaking and exemption,

requesting changes to the rule allowing

use of this equipment. During the

1990’s, the FAA received petitions for

rulemaking to allow foreign parachutists

to jump in the United States without an

exemption. Additionally, petitioners
