REGULATORY TEXT:  
91-05-12 AIRBUS INDUSTRIE: Amendment 39-6914. Docket No. 90-NM-158-AD.

Applicability: All Model A300 series airplanes, equipped with one or more trimmable horizontal stabilizer (THS) attachment lugs made from 2014 material, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To detect cracks and corrosion in the THS attachment lugs at Frame 91 and to prevent reduced structural integrity of the horizontal stabilizer attachment, accomplish the following:

A. Prior to the accumulation of 1,200 landings, or within 90 days after the effective date of this AD, whichever occurs later, unless previously accomplished within the last 1,200 landings, perform a visual and eddy current inspection of all attachment lugs made from 2014 material, in accordance with Airbus Industrie Service Bulletin A300-53-269, dated December 18, 1989. Repeat these inspections thereafter at intervals not to exceed 1,200 landings.

NOTE: Attachment lugs made from 7075 material are not affected by this AD.

B. If cracks or corrosion are detected, prior to further flight, repair or replace the affected lugs in accordance with Airbus Industrie Service Bulletin A300-53-269, dated December 18, 1989.

C. Installation of Modification No. 7715/D7222, in accordance with Airbus Industrie Service Bulletin A300-53-270, Revision 1, dated February 22, 1990, or Revision 2, dated August 27, 1990, constitutes terminating action for the repetitive inspections required by paragraph A. of this AD.

D. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

NOTE: The request should be submitted directly to the Manager, Standardization Branch, ANM-113, and a copy sent to the cognizant FAA Principal Inspector (PI). The PI will then forward comments or concurrence to the Manager, Standardization Branch, ANM-113.

E. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to Airbus Industrie, Airbus Support Division, Avenue Didier Daurat, 31700 Blagnac, France. These documents may be examined at the FAA, Northwest Mountain Region, Transport Airplane Directorate, 1601 Lind Avenue S.W., Renton, Washington.

This amendment (39-6914, AD 91-05-12) becomes effective on April 1, 1991.
