This Airworthiness Directive (AD) applies to AIRBUS INDUSTRIE A300, A310 and A300-600 aircraft, all certified models and all serial numbers, on which AIRBUS INDUSTRIE modification No. 04443 has not been embodied, and which are not fitted with the door and landing gear alternate release device using the yellow hydraulic system, post mod 02781, (AIRBUS INDUSTRIE Service Bulletins (SB) A300-32-272 or A300-32-332) and pre mod 03433.

In order to detect and prevent any incorrect rigging of the landing gear free fall control mechanism, in which case the cockpit control handle could reach its mechanical stop (after 20.4 turns) before landing gear release and extension take place, the following measures are rendered mandatory.

Within 600 flight hours following the effective date of this AD at original issue, perform an operational test (aircraft on wheels) of the landing gear free fall mechanism and readjust if required, in accordance with the instructions of paragraph 4.2.1. of A.O.T. 32-14 Rev.1 dated March 13,1997.

Note 1: Inform AIRBUS INDUSTRIE of all inspection results including nil findings.

Note 2: On the effective date of this AD at original issue, aircraft having already performed A.O.T. 32-14 dated February 3,1997 successfully are not affected by paragraph 1 of this AD.

2. Before March 31,1998, perform a functional test (aircraft on jacks) in accordance with the instructions of paragraph 422. of AIRBUS INDUSTRIE A.O.T. No. 32-14 Rev. 1 dated March 13,1997.

3. Repeat the functional test described above at one year intervals.
