Docket ID: [Docket No. 98-NM-56-AD; Amendment 39-11725; AD 2000-10-01]

RIN ID: RIN 2120-AA64

NOTICE: RULES

ACTION: Airworthiness directives:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: Airworthiness Directives; Airbus Model A300 B2, A300-B2K, A300 B4-2C, A300 B4-100, and A300 B4-200 Series Airplanes

DATES: Effective June 28, 2000.

The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of June 28, 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 April 13, 1992 (57 FR 8257, March 3, 1992), and as of May 29, 1996 (61 FR 18661, April 29, 1996).

DOCUMENT SUMMARY: This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 B2, A300 B2K, A300 B2200, A300 B4, A300 B4100, and A300 B4200 series airplanes, that currently requires certain structural inspections and modifications. This amendment requires that those inspections be accomplished on additional airplanes. This action also requires new repetitive inspections for airplanes in certain configurations at revised thresholds and intervals. 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 and correct corrosion and cracking of the wings and fuselage, which could result in reduced structural integrity of the airplane.

SUMMARY: Airbus,

SUPPLEMENTAL INFORMATION

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 960808, amendment 399574 (61 FR 18661, April 29, 1996), which is applicable to all Airbus Model A300 B2, A300 B2K, A300 B2200, A300 B4, A300 B4100, and A300 B4200 series airplanes, was published in the Federal Register on December 21, 1999 (64 FR 71333). The action proposed to continue to require certain structural inspections and modifications. The action proposed to require that those inspections be accomplished on additional airplanes. The action also proposed to require new repetitive inspections for airplanes in certain configurations at revised thresholds and intervals.

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.

Additional Affected Airbus Models

One commenter suggests that the applicability of the proposed AD be [[Page 33442]]
revised to include Airbus Model A300C4200 and A300F4200 series airplanes. The FAA does not concur that the applicability should be revised to include these airplane models, since they are not type certificated in the U.S. No change is made to the final rule. Reference to French Airworthiness Directive

One commenter suggests that the proposed AD be revised to include a reference to a related French airworthiness directive. The commenter states that the proposed AD correctly refers to French airworthiness directive 90222116(B)R4, which references service bulletins for certain inspections also addressed in this proposed AD, but does not mention 93154149(B), which references service bulletins for the modifications addressed by this AD.

The FAA acknowledges that the modifications required by existing FAA AD 960808 were also addressed in related French airworthiness directive 93154149(B), dated September 15, 1993. The FAA has no objection to including this reference in this final rule, which continues to require those modifications, and has revised the AD 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. Changes Made to Proposed AD

To improve the readability of the AD, the FAA has added certain headings to the text of the AD.

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 changes previously described. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

Cost Impact

There are approximately 13 airplanes of U.S. registry that will be affected by this AD.

The actions that are currently required by AD 960808, and retained in this AD, 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 the previously required actions on U.S. operators is estimated to be $120 per airplane, per inspection cycle.

The new inspection that is required by this new AD will take approximately 3 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 new requirements of this AD on U.S. operators is estimated to be $180 per airplane, per inspection cycle.

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.

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 39AIRWORTHINESS 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 399574 (61 FR 18661, April 29, 1996), and by adding a new airworthiness directive (AD), amendment 3911725, to read as follows:
20001001 Airbus Industrie: Amendment 3911725. Docket 98NM56 AD. Supersedes AD 960808, Amendment 399574.

Applicability: All Model A300 B2, A300 B2K, A300 B2200, A300 B42C, A300 B4100, and A300 B4200 series airplanes, certificated in any category.

Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been 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 (h) 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 detect and correct corrosion and cracking of the wings and fuselage, which could result in reduced structural integrity of the airplane, accomplish the following:
