Federal Register / Vol. 61, No. 83 / Monday, April 29, 1996 / Proposed Rules 18709

Regulatory Impact

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

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 Airbus Model A320 series

airplanes. This proposal would require

an inspection to detect damage to the

electrical wiring of the fuel tank of the

wings and to verify if the proper P-clip

is installed in the electrical wiring. The

proposed AD would also require refitting any proper P-clip, replacing any

improper P-clip with a new P-clip, and

repairing damaged electrical wiring.

This proposal is prompted by a report

that incorrect P-clips were found

installed in the electrical wiring of the

fuel system on these airplanes. The

actions specified by the proposed AD

are intended to ensure that the proper

P-clips are installed. Improper P-clips

could fail to adequately safeguard the

fuel tank of the wing against a lightning

strike, which could result in electrical

arcing and resultant fire.

DATES: Comments must be received by

June 10, 1996.

Discussion

The Direction Go ́no ́rale de l’Aviation

Civile (DGAC), which is the

airworthiness authority for France,

recently notified the FAA that an unsafe

condition may exist on certain Airbus

Model A320 series airplanes. The DGAC

advises that it has received a report that

incorrect P-clips were found installed in

the electrical wiring of the fuel system

on these airplanes. Investigation

revealed that, during production,

skydrol-resistant ethylene propylene Pclips were installed instead of fuelresistant P-clips. Skydrol- resistant

ethylene propylene P-clips are not

suitable for immersion in fuel. Such

immersion causes these clips to swell

and lose flexibility. If the skydrolresistant ethylene propylene P-clips

were to bend slightly, they could

fracture and deteriorate, which could

fail to adequately safeguard the fuel tank

of the wing against a lightning strike.

This condition, if not corrected, could

result in electrical arcing and

consequent fire.

Explanation of Relevant Service

Information

Airbus has issued Service Bulletin

A320–28–1052, Revision 1, dated July 7,

1993, and Revision 2, dated September

8, 1994. The service bulletins describe

procedures for a one-time inspection to

detect damage to the electrical wiring

and to verify if the proper P-clip is

installed in the electrical wiring at

outboard rib 6 in the inner cell of the

fuel tank of the wings. The service

bulletins also describe procedures for

re-fitting proper P-clips, and replacing

improper P-clips with a new fuelresistant P-clip having P/N NSA5515–

03NF or NSA5516–03NV. The DGAC

classified the service bulletins as

mandatory and issued French

airworthiness directive 93–191–047(B),

dated October 27, 1993, in order to

assure the continued airworthiness of

these airplanes in France.

FAA’s Conclusions

This airplane model is manufactured

in France and is type certificated for

operation in the United States under the

provisions of section 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 the Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design, the proposed AD would

require a one-time inspection to detect

damage to the electrical wiring and to

verify if the proper P-clip is installed in

the electrical wiring at outboard rib 6 in

the inner cell of the fuel tank of the

wings. The proposed AD would also

require re-fitting proper P-clips, and

replacing improper P-clips with certain

new fuel-resistant P-clips. The actions

would be required to be accomplished

in accordance with the service bulletin

described previously. If any damage is

detected to the electrical wiring, the

repair would be required to be done in

accordance with the Airplane Wiring

Manual.

Cost Impact

The FAA estimates that 44 Airbus

Model A320 series airplanes of U.S.

registry would be affected by this

proposed AD, that it would take

approximately 3 work hours per

airplane to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Required parts

would cost approximately $100 per

airplane. Based on these figures, the cost

impact of the proposed AD on U.S.

operators is estimated to be $12,320, or

$280 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.

Regulatory Impact

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

cleaning operations. These regulations

were submitted to generate reductions

in VOC emissions, which the State will

use to fulfill the 15 percent requirement

of the amended Clean Air Act. In the

final rules of this Federal Register, the

EPA is approving this action as a direct

final without prior proposal because

EPA views this as a noncontroversial

action and anticipates no adverse

comments. If no adverse comments are

received in response to that direct final

rule, no further activity is contemplated

in relation to this proposed rule. If EPA

receives adverse comments, the direct

final rule will be withdrawn and all

public comments received will be

addressed in a subsequent final rule

based on this proposed rule. The EPA

will not institute a second comment

period on this action. Any parties

interested in commenting on this

document should do so at this time.
