Airworthiness Directive · Amendment 39-10646 · Airbus Model A300, A310, A300-600 Series Airplanes
Airbus Model A300, A310, A300-600 Series Airplanes
Superseded. A later AD replaced this one: AD 99-25-15. Comply with the one in force.
Model A300, A310, and A300-600 series airplanes; on which Airbus Industrie Modification 02781 has been accomplished, and on which Airbus Industrie Modification 03433 or 04443 has not been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300, A310, and A300-600 series airplanes. This amendment 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. This amendment 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 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.
