RIN 2120-AA64


Airworthiness Directives; Airbus Industrie Model A300, A300-600, 
and A310 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain Airbus Industrie Model A300, A300-600, and 
A310 series airplanes, that currently requires inspections to detect 
cracks in the lower spar axis of the pylons between ribs 6 and 7, and 
repair, if necessary. For certain Model A310 series airplanes, this 
amendment reduces the currently required inspection thresholds and 
intervals, and removes an option for a terminating modification. 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 such fatigue cracking, 
which could result in reduced structural integrity of the engine 
pylon's lower spar, and possible separation of the engine from the 
airplane.

DATES: Effective June 30, 2000.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of June 30, 2000.
    The incorporation by reference of certain other publications, as 
listed in the regulations, was approved previously by the Director of 
the Federal Register as of June 28, 1996 (61 FR 26091, May 24, 1996).

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) by superseding AD 96-11-05, 
amendment 39-9630 (61 FR 26091, May 24, 1996), which is applicable to 
certain Airbus Industrie Model A300, A300-600, and A310 series 
airplanes, was published in the Federal Register on February 14, 2000 
(65 FR 7316). The action proposed to continue to require inspections to 
detect cracks in the lower spar axis of the engine pylons for Airbus 
Model A300 and A300-600 series airplanes, and to require accomplishment 
of the actions specified in Airbus Service Bulletin A310-54-2017, 
Revision 03, for Model A310 series airplanes.

Comments Received

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

No Objection to the Proposal

    One commenter, an operator, states that it is not affected by the 
proposed AD, and therefore has no objection or additional comments.

[[Page 34056]]

Reference to French Airworthiness Directive

    One commenter, the manufacturer, requests that the proposed AD be 
revised to include a reference to a related French airworthiness 
directive. The commenter states that the proposed AD refers to French 
airworthiness directive 1999-239-287(B), which addresses Airbus Model 
A310 series airplanes, but does not mention 1993-228-154(B)R3, which 
addresses Airbus Model A300 and A300-600 series airplanes (actions for 
those airplanes are required in existing FAA AD 96-11-05).
    The FAA acknowledges that the actions required by existing FAA AD 
96-11-05 are related to French airworthiness directive 1993-228-154(B). 
The FAA has no objection to including the reference in this AD, which 
continues to require those actions for Model A300 and A300-600 series 
airplanes. ``NOTE 3'' of the AD has been revised accordingly. However, 
although the FAA generally references the latest pertinent 
airworthiness directive issued by another airworthiness authority as an 
informational Note in the AD, this information is not intended to be an 
exhaustive list of all related mandatory continuing airworthiness 
information, and should not be considered as such.

Conclusion

    After careful review of the available data, including the comments 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule with the change previously 
described. The FAA has determined that this change will neither 
increase the economic burden on any operator nor increase the scope of 
the AD.

Cost Impact

    There are approximately 146 airplanes of U.S. registry that will be 
affected by this AD.
    The requirements of this AD will not add any new additional 
economic burden on affected operators, other than the costs that are 
associated with accomplishing inspections for certain airplanes at an 
earlier time than would have been required by AD 96-11-05. The current 
costs associated with this AD are reiterated (as follows) for the 
convenience of affected operators.
    The inspections that are currently required by AD 96-11-05, and 
retained in this AD, take approximately 8 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 $480 per airplane, per inspection 
cycle.

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.

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:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by removing amendment 39-9630 (61 FR 
26091, May 24, 1996), and by adding a new airworthiness directive (AD), 
amendment 39-11742, to read as follows:

2000-10-18  Airbus Industrie: Amendment 39-11742. Docket 99-NM-251-AD. 
Supersedes AD 96-11-05, Amendment 39-9630.

    Applicability: The following models, certificated in any 
category: Model A300 and A300-600 series airplanes, as listed in 
Airbus Service Bulletins A300-54-0073 and A300-54-6014, both 
Revision 1, dated March 28, 1994; and Model A310 series airplanes, 
except those on which Airbus Modification 10149 has been 
accomplished.

    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 (m)(1) 
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 fatigue cracking, which could result in 
reduced structural integrity of the engine pylon's lower spar and 
possible separation of the engine from the airplane, accomplish the 
following:
