SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   85-09-05 AIRBUS INDUSTRIE: Amendment 39-5049. Applies to Models A300 B2 and B4 series airplanes, certificated in all categories. To detect failure of the trim actuators for the horizontal stabilizers, accomplish the following, unless previously accomplished:

A. Within 120 days after the effective date of this AD or upon reaching 4,000 flight hours time in service, whichever occurs later, perform a jamming detection test on actuators, part numbers: CHA723-30XX, CHA723-20XX, and CHA723-010 through CHA723-018, in accordance with the accomplishment instructions of Airbus Industrie (AI) Service Bulletin A300- 27-132, Revision 4, dated October 30, 1981. Any actuator that malfunctions during the jamming detection tests must be replaced before further flight.

B. Repeat the jamming detection test of paragraph A., above, as follows:

(1) On actuators, part numbers CHA723-30XX and CHA723-20XX, at intervals not to exceed 1,000 flight hours; and

(2) On actuators, part numbers CHA723-010 through CHA723-018, at intervals not to exceed 550 flight hours.

C. Within 120 days after the effective date of the AD or prior to the accumulation of 7,500 flight hours, whichever occurs later, overhaul actuators, part numbers CHA723-20XX and CHA723-010 through CHA723-018, and replace certain actuator's pinions and needle bearings listed in Lucas Aerospace (LA) Service Bulletin 723-27-584, dated January 5, 1980.

D. Within 120 days after the effective date of this AD or prior to the accumulation of 6,500 flight hours, whichever occurs later, perform an endoscopic inspection on actuators, part numbers CHA723-010 through CHA723-018, in accordance with the instructions of AI Service Bulletin A300-27-130, Revision 2, dated October 10, 1980, and LA Service Bulletin 723-27-582, Revision 1, dated July 27, 1979.

E. Upon request of an operator, an FAA Maintenance Inspector, subject to prior approval of the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region, may adjust the inspection times specified in this AD to permit compliance at an established inspection period of that operator, if the request contains substantiating data to justify the change for that operator.

F. Alternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

G. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD.

All persons affected by this directive who have not already received these documents from the manufacturer may obtain copies upon request to Airbus Industrie, Airbus Support Division, Centreda, Avenue Didier Daurat, 31700 Blagnac, France. These documents may also be examined at FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

This amendment becomes effective June 6, 1985.
