Airworthiness Directive · Amendment 39-11458 · Airbus Model A300, A310, A300-600 Series Airplanes
Airbus Model A300, A310, A300-600 Series Airplanes
Model A300, A300-600, and A310 series airplanes, certificated in any category, as identified below: Model A300 and A300-600 series airplanes on which Airbus Modification 02781 has been accomplished and on which neither Airbus Modification 03433 nor 04443 has been accomplished; Model A310 series airplanes on which Airbus Modification 02781 has been accomplished and on which Airbus Modification 03433 has not been accomplished; and Model A310 series airplanes on which Airbus Service Bulletin A310-32-2111, dated March 10, 1997, or Revision 01, dated October 10, 1997; has been accomplished.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Airbus Model A300, A310, A300-600 series airplanes, that currently requires a one-time operational test and repetitive functional tests of the free fall control mechanism of the landing gear to ensure proper release of the main landing gear (MLG), and corrective action, if necessary. It also requires eventual modification of the free fall control mechanism of the landing gear, which constitutes terminating action for the repetitive functional tests. This amendment requires, for certain airplanes, that the modification of the free fall control mechanism of the landing gear be accomplished in accordance with a corrected version of the manufacturer's service bulletin. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent malfunction of the free fall control mechanism of the landing gear, which could result in the inability to extend the MLG in the event of failure of the hydraulic extension system.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
