82-06-05 CANADAIR: Amendment 39-4345. Applies to Model CL-600 airplanes serial numbers 1005 thru 1008 and 1010 thru 1023 certificated in all categories. To ensure correct functioning of the landing gear manual release control system, accomplish the following, unless already accomplished.

1. Within the next 50 hours time in service after the effective date of this AD determine the manual release handle travel required for full extension and down locking of the nose and main gears. If full extension and down locking of the gear requires moving the handle to the fourth hole position, modify the system in accordance with paragraph 2B of Canadair Alert Service Bulletin A600-0076, Revision 1, dated October 22, 1981, prior to further flight.

2. If full extension and down locking of the gear is achieved by moving the handle to less than the fourth hole position, modify the system in accordance with paragraph 2B of the service bulletin within the next 150 hours time in service.3. Airplanes may be flown in accordance with FAR 21.197 to a maintenance base for accomplishment of the inspection required by this AD.

4. Alternate methods of compliance with this AD may be used when they provide an equivalent level of safety and are approved by the Chief, Seattle Area Aircraft Certification Office, FAA Northwest Mountain Region.

The manufacturer's specifications and procedures identified and described in this directive are incorporated herein and made a part hereof pursuant to 5 U.S.C. 552(a)(1).

This amendment becomes effective March 22, 1982.
