Airworthiness Directive · Amendment 39-11495 · Airbus Model A340-211, -212, -213, - 311, -312, and -313 Series Airplanes
Airbus Model A340-211, -212, -213, - 311, -312, and -313 Series Airplanes
All Model A340-211, -212, -213, -311, -312, and - 313 series airplanes; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A340-211, -212, -213, -311, -312, and -313 series airplanes, that currently requires repetitive operational tests to ensure proper operation of the actuator of the secondary locks of the thrust reversers, and corrective actions, if necessary. The previously optional modifications that would have allowed an extension of the repetitive test intervals have been removed from this amendment. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent the inadvertent opening of a thrust reverser door in the event of failure of the primary and secondary locks of the thrust reverser. Such inadvertent opening could result in reduced controllability of the airplane.
Required as indicated, unless accomplished previously.
To prevent the inadvertent opening of a thrust reverser door in the event of failure of the primary and secondary locks of the thrust reverser, which could result in reduced controllability of the airplane, accomplish the following:
Operational Test
(a) Prior to the accumulation of 1,300 total flight hours, or within 500 flight hours after January 25, 1999 (the effective date of AD 99-01-15, amendment 39-10980), whichever occurs later, perform an operational test (inspection) to ensure proper operation of the actuator of the secondary locks of the thrust reversers, in accordance with Airbus Service Bulletin A340-78-4012, Revision 01, dated December 19, 1996, or Revision 05, dated July 6, 1999. Thereafter, repeat the operational test at intervals not to exceed 1,300 flight hours. After the effective date of this AD, only Revision 05 of the service bulletin shall be used.
Note 2: The Airbus service bulletin references ROHR Service Bulletin RA34078-47, Revision 1, dated November 30, 1996, as an additional source of service information for accomplishment of the operational test.
Corrective Action
(b) If any discrepancy is detected during any operational test (inspection) required by paragraph (a) of this AD, prior to further flight, replace the actuator of the secondary lock with a new or serviceable actuator, in accordance with ROHR Service Bulletin RA34078-47, Revision 1, dated November 30, 1996.
