Airworthiness Directives; Airbus Model A300 B4-600R and A300 F4-
600R Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment supersedes an existing airworthiness directive
(AD), applicable to all Airbus Model A300 B4-600R and A300 F4-600R
series airplanes, that currently requires a one-time visual inspection
for damage of the center tank fuel pumps and fuel pump canisters, and
replacement of damaged fuel pumps and fuel pump canisters with new or
serviceable parts. This amendment also requires repetitive visual
inspections of the fuel pumps and repetitive eddy current inspections
of the fuel pump canisters, and replacement of damaged fuel pumps and
fuel pump canisters with new or serviceable parts. This amendment also
reduces the applicability to include only those airplanes that have a
trim tank system installed. 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 detect damage to the fuel pump and fuel pump canister, which could
result in loss of flame trap capability and could provide a fuel
ignition source in the center fuel tank.
DATES: Effective February 8, 2000.
The incorporation by reference of Airbus Alert Service Bulletin
A300-28A6061, dated February 19, 1999, as listed in the regulations, is
approved by the Director of the Federal Register as of February 8,
2000.
The incorporation by reference of Airbus All Operators Telex (AOT)
28-
[[Page 214]]
09, dated November 28, 1998, as listed in the regulations, was approved
previously by the Director of the Federal Register as of December 28,
1998 (63 FR 70639, December 22, 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,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) by superseding AD 98-25-53,
amendment 39-10956 (63 FR 70639, December 22, 1998), which is
applicable to all Airbus Model A300 B4-600R and A300 F4-600R series
airplanes, was published in the Federal Register on October 27, 1999
(64 FR 57800). The action proposed to require a one-time visual
inspection for damage of the center tank fuel pumps and fuel pump
canisters, and replacement of damaged fuel pumps and fuel pump
canisters with new or serviceable parts. The action also proposed to
require repetitive visual inspections of the fuel pumps and repetitive
eddy current inspections of the fuel pump canisters, and replacement of
damaged fuel pumps and fuel pump canisters with new or serviceable
parts. The action also proposed to reduce the applicability to include
only those airplanes that have a trim tank system installed.
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
There are approximately 67 airplanes of U.S. registry that will be
affected by this AD.
The inspection that is currently required by AD 98-25-53, and
retained in this AD, takes approximately 2 work hours per airplane to
accomplish, at an average labor rate of $60 per work hour. Based on
these figures, the cost impact of the currently required actions on
U.S. operators is estimated to be $120 per airplane.
The new inspections that are required in this AD action will take
approximately 2 work hours per airplane to accomplish, at an average
labor rate of $60 per work hour. Based on these figures, the cost
impact of this requirement of this AD on U.S. operators is estimated to
be $8,040, or $120 per airplane, per inspection cycle.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the current or 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 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
