Compliance: Required as indicated, unless accomplished previously.

To prevent cracking and reduced structural capability of the forward partial pressure bulkhead and subsequent decompression of the airplane, accomplish the following:

NOTE: Operators who have accomplished the appropriate installation in accordance with the originally issued Fokker Service Bulletin SBF100-53-052, dated January 17, 1992, are considered to be in compliance with this paragraph.

(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113.

NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113.

(c) 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.
