Required as indicated, unless accomplished previously.

Do the inspection and corrective action per the Accomplishment Instructions of the service bulletin. Do the related corrective action before further flight. Note 1: For the purposes of this AD, a general visual inspection is defined as: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to enhance visual access to all exposed surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” Related Service Information Note 2: Fokker Service Bulletin F27/54-53, dated February 15, 2002, references Fokker Service Bulletin 51-24, dated December 1, 1971, as the appropriate source of service information for installing a new, improved engine mounting frame; and Fokker Service Bulletin F27/54-26, Revision 5, dated September 30, 2001, as the appropriate source of service information for installing new, improved, stronger brace struts and brackets.
