39–10535; AD 98–11–08]

RIN 2120–AA64

Airworthiness Directives; Airbus Model

A300, A310, and A300–600 Series

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Airbus Model

A300, A310, and A300–600 series

airplanes, that requires replacement of

the non-return valves located in the

engine fuel feed lines on the outer fuel

tank with new return valves; and, for

certain airplanes, replacement of the

inner tank booster pump canisters with

modified canisters. This amendment is

prompted by issuance of mandatory

continuing airworthiness information by

a foreign civil airworthiness authority.

The actions specified by this AD are

intended to prevent sticking of nonreturn valves located in the fuel system,

which could result in an internal fuel

transfer from the center tank to the inner

or outer tank. Such a transfer of fuel

could lead to fuel spillage overboard

through the vent system, and

consequent insufficient fuel for the

airplane to reach its flight destination.

DATES: Effective June 24, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of June 24,

1998.

ADDRESSES: The service information

referenced in this AD may be obtained

from Airbus Industrie, 1 Rond Point

Maurice Bellonte, 31707 Blagnac Cedex,

France. This information may be

examined at the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, Rules Docket,

1601 Lind Avenue, SW., Renton,

Washington; or at the Office of the

Federal Register, 800 North Capitol

Street, NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Airbus

Model A300, A310, and A300–600

series airplanes was published in the

Federal Register on March 27, 1998 (63

FR 14849). That action proposed to

require replacement of the non-return

valves located in the engine fuel feed

lines on the outer fuel tank with new

return valves; and, for certain airplanes,

replacement of the inner tank booster

pump canisters with modified canisters.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. Due

consideration has been given to the

single comment received.

The commenter supports the

proposed rule.

Conclusion

After careful review of the available

data, including the comment noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

The FAA estimates that 103 Model

A300, A310, and A300–600 series

airplanes of U.S. registry will be affected

by this AD.

The FAA estimates that the required

replacement of the non-return valves

will take approximately 66 work hours
Federal Register / Vol. 63, No. 97 /Wednesday, May 20, 1998 /Rules and Regulations 27675

per airplane to accomplish, at an

average labor rate of $60 per work hour.

Required parts will be supplied by the

manufacturer at no cost to the operators.

Based on these figures, the cost impact

of this action required by this AD on

U.S. operators is estimated to be

$407,880, or $3,960 per airplane.

The FAA estimates that the required

replacement of the inner fuel tank

booster pump canisters will take

approximately 12 work hours per

airplane to accomplish, at an average

labor rate of $60 per work hour.

Required parts will be supplied by the

manufacturer at no cost to the operators.

Based on these figures, the cost impact

of this action required by this AD on

U.S. operators is estimated to be

$74,160, or $720 per airplane.

The cost impact figures discussed

above are based on assumptions that no

operator has yet accomplished any of

the 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 adopted herein will

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 final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979); and (3)

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 final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends 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:

installed; 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 sticking of non-return valves

located in the fuel system, which could result

in fuel spillage overboard and consequent

insufficient fuel for the airplane to reach its

flight destination, accomplish the following:

(a) Within 18 months after the effective

date of this AD, accomplish paragraphs (a)(1)

and (a)(2) of this AD, as applicable.

Revision 01 (for Model A300 series

airplanes); Airbus Service Bulletin A310–28–

2053, Revision 01 (for Model A310 series

airplanes); or Airbus Service Bulletin A300–

28–6031, Revision 01 (for Model A300–600

series airplanes); all dated January 15, 1997;

as applicable.

(2) For extended range twin-engine

operations (ETOPS) airplanes, or airplanes

equipped with auxiliary tanks; on which

(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,

International Branch, ANM–116, FAA,

Transport 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, International Branch,

ANM–116.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the International Branch,

ANM–116.

(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
