REGULATORY TEXT:  
92-14-03 AIRBUS INDUSTRIE: Amendment 39-8285. Docket No. 91-NM-250-AD.

Applicability: Model A320 series airplanes on which Modification 22155 has not been accomplished, certificated in any category.

Compliance: Required as indicated, unless accomplished previously.

To prevent a short circuit of the hydraulic fire shut off valve actuator, which could result in the inability to shut off fuel to the engine in the event of an engine fire, accomplish the following:

(a) Within 400 hours time-in-service after the effective date of this AD, perform an inspection of the hydraulic fire shut off valve to ascertain the part number (P/N) of the actuator, in accordance with Airbus Industrie All Operator Telex (AOT) 29-04, Revision 1, dated June 1, 1991.

(b) If the actuator does not have P/N "E0 1100," without Amendment designation; or P/N "E0 1100, Amendment B": No further action is required.

(c) If the actuator has P/N "E0 1100," without Amendment designation; or P/N "E0 1100, Amendment B": Within 400 hours time-in-service after the effective date of this AD, perform an operational test of the fire shut off valve in accordance with Chapter 29-10-00, page 501, of the airplane maintenance manual.

(1) If the valve passes the operational test, repeat that operational test at intervals not to exceed 400 hours time-in-service.

(2) If the valve fails the operational test, prior to further flight, replace the actuator in accordance with Airbus Industrie All Operator Telex (AOT) 29-04, Revision 1, dated June 1, 1991.
(i) If the replacement actuator has P/N "E0 1100, Amendment A"; or P/N "E0 1100, Amendment AB"; or P/N "E0 1100, Amendment C"; or P/N "A06 A00": No further action is required.
(ii) If the replacement actuator has P/N "E0 1100," without Amendment designation; or P/N "E0 1100, Amendment B": Repeat the operational test at intervals not to exceed 400 hours time-in-service.

(d) Prior to the accumulation of 4,000 hours time-in-service after the effective date of this AD, replace each actuator that has P/N "EO 1100," without Amendment designation; or P/N "EO 1100, Amendment B"; with an actuator having P/N "EO 1100, Amendment A"; or P/N "EO 1100, Amendment AB"; or P/N "EO 1100, Amendment C"; or P/N "A06 A00." Accomplishment of this replacement constitutes terminating action for the repetitive operational tests required by this AD.

(e) 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.

(f) 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.

(g) The inspection and replacement shall be done in accordance with Airbus Industrie All Operator Telex (AOT) 29-04, Revision 1, dated June 1, 1991. 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 Airbus Industrie, Airbus Support Division, Avenue Didier Daurat, 31700 Blagnac, France. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue SW., Renton, Washington; or at the Office of the Federal Register, 1100 L Street NW., Room 8401, Washington, DC.

(h) This amendment becomes effective on August 18, 1992.
