(1) For airplanes that have accumulated less than 20,000 total landings as of the effective date of this AD: Prior to the accumulation of 20,000 total landings, or within 1 year after the effective date of this AD, whichever occurs later.

(2) For airplanes that have accumulated 20,000 or more total landings, but less than 30,000 total landings, as of the effective date of this AD: Prior to the accumulation of 30,000 total landings, or within 5 months after the effective date of this AD, whichever occurs later.

(b) If any crack is found as a result of the inspection required by paragraph (a) of this AD, prior to further flight, repair in accordance with a method approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate.

(c) Within 10 days after accomplishing the inspection required by paragraph (a) of this AD, report positive findings of cracks to Fokker, in accordance with Fokker Service Bulletin F27/57-69, dated April 6, 1992.

(e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished.

(f) The inspection and report shall be done in accordance with Fokker Service Bulletin F27/57-69, dated April 6, 1992.
