AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment supersedes

an existing airworthiness directive (AD)

that is applicable to GE Aircraft Engines

(GEAE) CJ610 series turbojet and CF700

series turbofan engines that currently

requires removal of certain unapproved

parts before further flight. This

amendment requires removal of

additional unapproved parts. This

amendment is prompted by the

discovery by the FAA of additional

unapproved parts not listed in the

original AD that have been introduced

into the field and might be installed on

the affected engines. The actions

specified in this AD are intended to

prevent the use of unapproved parts

which could lead to an uncontained

Federal Register / Vol. 66, No. 100 / Wednesday, May 23, 2001 / Rules and Regulations 28365

engine failure and damage to the

airplane.

DATES: Effective June 7, 2001.

Comments for inclusion in the Rules

Docket must be received on or before

July 23, 2001.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), New England

Region, Office of the Regional Counsel,

Attention: Rules Docket No. 99–NE–58–

AD, 12 New England Executive Park,

Burlington, MA 01803–5299. Comments

may also be sent via the Internet using

the following address: ‘‘9-aneadcomment@faa.gov’’. Comments sent

via the Internet must contain the docket

number in the subject line.

FOR FURTHER INFORMATION CONTACT:

Kevin Donovan, Aerospace Engineer,

Engine Certification Office, FAA, Engine

and Propeller Directorate, 12 New

England Executive Park, Burlington, MA

01803–5299; telephone (781) 238–7743,

fax (238) 238–7199.

SUPPLEMENTARY INFORMATION: On

January 5, 2000, the FAA issued AD

2000–01–09, Amendment 39–11506 (65

FR 1771) to require removal of certain

unapproved parts before further flight.

That amendment was prompted by

findings that life-limited parts, with

inaccurate records, have been

introduced into the field and might be

installed on the affected engines. That

condition, if not corrected, could lead to

an uncontained engine failure and

damage to the airplane.

Since the issuance of that AD, the

FAA discovered a compressor rotor

during an audit with suspected military

markings. The manufacturer confirmed

that the marking was an electro-etched

Low Cycle Fatigue Cycles (LCFC)

marking used strictly on military parts.

The original AD, AD 2000–01–09, did

not identify this particular compressor

rotor or the three additional rotors

containing unapproved parts discovered

at other locations during subsequent

audits.

FAA’s Determination of an Unsafe

Condition and Proposed Actions

Since an unsafe condition has been

identified that is likely to exist or

develop on other GE Aircraft Engines

(GEAE) CJ610 series turbojet and CF700

series turbofan engines of the same type

design, this AD supersedes AD 2000–

01–09 to require removal before further

flight of the additional unapproved

parts not listed in the original AD that

have been introduced into the field and

might be installed on the affected

engines.

Immediate Adoption of This AD

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in less than 30 days.

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 99–NE–58–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.

List of Subjects in 14 CFR Part 39
