AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/M20/28.

Mooney M20 Series Aeroplanes

AD/M20/28 Automatic Pilot Control Wheel Disengage Switch Circuit - Modification 5/2009

Requirement:

CANCELLED.

This AD is cancelled on 7 May 2009.

Background:

This unique Australian AD was raised in 1977 against Mooney Service Bulletin (SB) No. M20-199 requiring a modification to correct the possibility of the electrical elevator trim system control wheel disengage switch from becoming inoperative if the "TRIM" circuit breaker is tripped.

Compliance was: Before 30 September 1977.

This AD has been sufficiently promulgated for the affected aircraft to have been modified by now; therefore this AD is no longer required.
