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 all Airbus Model A300, A310, and A300-600 series 
airplanes, that requires an inspection to detect damage of the 
electrical bonding leads in specified locations of the fuel tanks, and 
replacement of any damaged

[[Page 37020]]

electrical bonding leads with serviceable electrical bonding leads. For 
certain airplanes, this amendment also requires modifying the fuel pipe 
couplings in specified locations of the fuel tank. 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 electrical arcing/discharge in the fuel 
tank due to damaged electrical bonding leads or inadequate electrical 
bonding of the fuel pipe couplings, which could result in fuel ignition 
and consequent uncontained rupture of the fuel tank.

DATES: Effective July 18, 2000.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 18, 2000.

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.

FOR FURTHER INFORMATION CONTACT: Norman B. Martenson, Manager, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-2110; fax (425) 227-1149.

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 all Airbus Model A300, A310, and 
A300-600 series airplanes was published in the Federal Register on 
March 27, 2000 (65 FR 16151). That action proposed to require an 
inspection to detect damage of the electrical bonding leads in 
specified locations of the fuel tanks, and replacement of any damaged 
electrical bonding leads with serviceable electrical bonding leads. For 
certain airplanes, that action also proposed to require modifying the 
fuel pipe couplings in specified locations of the fuel tank.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    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 116 airplanes of U.S. registry will be 
affected by this AD.
    It will take between 70 and 80 work hours per airplane to 
accomplish the required inspection, at an average labor rate of $60 per 
work hour. Based on these figures, the cost impact of the required 
inspection on U.S. operators is estimated to be between $487,200 and 
$556,800, or between $4,200 and $4,800 per airplane.
    It will take between 77 and 103 work hours per airplane to 
accomplish the required modification, at an average labor rate of $60 
per work hour. Required parts will cost approximately $104 per 
airplane. Based on these figures, the cost impact of the required 
modification on U.S. operators is estimated to be between $547,984 and 
$728,944, or between $4,724 and $6,284 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 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 final rule does not have federalism 
implications under Executive Order 13132.
    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.
