Discussion

The Direction Ge ́ne ́rale de l’Aviation

Civile (DGAC), which is the

airworthiness authority for France,

notified the FAA that an unsafe

condition may exist on certain Airbus

Model A330 and A340 series airplanes.

The DGAC advises that it has received

a report of a failed crossbolt of the the

brake rod attachment pin and a partially

migrated attachment pin on the main

landing gear (MLG) of a Model A330

series airplane. After the airplane

landed, a walkaround inspection

revealed that the attachment pin had

migrated nearly half its length. The

collar and the head and tail of the

crossbolt, which retain the attachment

pin in position, were missing. The

complete migration of an attachment

pin will result in the loss of braking on

two wheels. It is also possible that the

free movement of a disconnected brake

torque rod could restrict the extension

of the MLG.

The MLG on Model A330 and A340

series airplanes is similar; therefore,

both airplane models are subject to the

unsafe condition identified in this

proposed AD.

Explanation of Relevant Service

Information

Airbus has issued Service Bulletins

A330–32–3119 (for Model A330 series

airplanes) and A340–32–4157 (for

Model A340 series airplanes), both

dated July 13, 2000. The service

bulletins describe procedures for

installing a retainer device on the

attachment pin of the brake torque rods

of the MLG. The retainer will:

• Prevent the attachment pin from

fully migrating if the crossbolt fails and

the collar moves out of position;

• Allow for easier detection of a

failed crossbolt and a loose collar; and

• Prevent the collar from becoming

detached from the MLG.

The DGAC classified these service

bulletins as mandatory and issued

French airworthiness directives 2000–

478–130(B) and 2000–479–157(B), both

dated November 29, 2000, to ensure the

continued airworthiness of these

airplanes in France. Accomplishment of

the actions specified in the service

bulletins is intended to adequately

address the identified unsafe condition.

The service bulletins refer to MessierDowty Service Bulletins A33/34–32–163

and A33/34–32–164, both dated March

1, 2000, as additional sources of service

information for accomplishment of the

installation required by this AD.

FAA’s Conclusions

These airplane models are

manufactured in France and are type

certificated for operation in the United

States under the provisions of § 21.29 of

the Federal Aviation Regulations (14

CFR 21.29) and the applicable bilateral

airworthiness agreement. Pursuant to

this bilateral airworthiness agreement,

the DGAC has kept the FAA informed

of the situation described above. The

FAA has examined the findings of the

DGAC, reviewed all available

information, and determined that AD

action is necessary for products of this

type design that are certificated for

operation in the United States.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, the proposed AD would require

accomplishment of the actions specified

in the service bulletins described

previously.

Cost Impact

The FAA estimates that 7 airplanes of

U.S. registry would be affected by this

proposed AD.

It would take approximately 4 work

hours per airplane to accomplish the

proposed retainer installation, at an

average labor rate of $60 per work hour.

There would be no charge for required

parts. Based on these figures, the cost

impact on U.S. operators of the retainer

installation proposed by this AD is

estimated to be $1,680, or $240 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 proposed AD were not adopted. The

cost impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations proposed herein

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. Therefore,

it is determined that this proposal

would 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

21296 Federal Register / Vol. 66, No. 83 / Monday, April 30, 2001 / Proposed Rules

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
