Applicability: Model F28 Mk 0100 series airplanes, serial numbers 11244 through 11392 inclusive; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent inadvertent positive voltage on the wiring of the liftdumper system, accomplish the following:

If any shield is not connected to ground, prior to further flight, connect the shield to ground in accordance with the service bulletin.

(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, FAA, Transport Airplane Directorate. 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.

(d) The inspection and connection shall be done in accordance with Fokker Service Bulletin SBF100-27-043, dated October 1, 1992.
