REGULATORY TEXT:  
93-08-05 FOKKER: Amendment 39-8552. Docket 92-NM-196-AD.
Applicability: All Model F27 series airplanes, excluding Model F27 Mark 050 airplanes; certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent failure of an aileron control cable and subsequent reduced aileron roll control authority, accomplish the following:

(a) Within 500 hours time-in-service or 2 months after the effective date of this AD, whichever occurs first, inspect the noise filter capacitors mounted on the rotary flap actuator to detect damage and to determine the manufacturer and part number, in accordance with Fokker Service Bulletin F27/27-135, dated June 1, 1992.

(1) If no damaged capacitor is found, and if no capacitor manufactured by John E. Fast Company and having part number A-16446 is installed, no further action is required by this AD.

(2) If any damaged capacitor is found, or if any capacitor manufactured by John E. Fast Company and having part number A-16446 is found, prior to further flight, replace that capacitor with either a capacitor manufactured by P.R. Mallory Company and having part number CA275X, or a capacitor manufactured by Potter Company and having part number 1136-5004, 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 replacement shall be done in accordance with Fokker Service Bulletin F27/27-135, dated June 1, 1992. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR Part 51. Copies may be obtained from Fokker Aircraft USA, Inc., 1199 North Fairfax Street, Alexandria, Virginia 22314.
