ADDRESSES: FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: REGULATORY TEXT: 85-09-02 BOEING: Amendment 39-5057. Applies to all Model 767-200 airplanes, certificated in all categories, listed in Boeing Service Bulletin 767-55-0005, dated March 29, 1985. This AD is required to detect or avert cracked horizontal stabilizer pivot pins which could fail during flight, resulting in a reduction in the controllability of the airplane. Unless already accomplished, accomplish the following prior to the accumulation of 6,000 total landings, or within 200 landings after the effective date of this AD, whichever occurs later, in accordance with Boeing Service Bulletin 767-55-0005, dated March 29, 1985, or later FAA approved revision: A. Remove the horizontal stabilizer inner pivot pins and ultrasonically inspect the outer pins for cracks. B. If an outer pivot pin is found cracked, replace it with an improved outer pivot pin before further flight. C. Replace the inner pivot pins with improved inner pivot pins, whether or not cracks are found in the outer pin. D. If no cracks are found in the outer pivot pin, the joint must be reassembled with a new inner pivot pin and the existing outer pivot pin must thereafter be reinspected at intervals not to exceed 12,000 landings. Terminating action for the repeat inspections of the outer pivot pin consists of replacing the existing outer pivot pin with an improved outer pivot pin, in accordance with Boeing Service Bulletin 767-55-0005 dated March 29, 1985, or later FAA approved revision. Alternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD.
