AD/GOV/9 Governor Control Arm Attachment Cap Screw A-1635-105 Replacement Cancelled (Cth)

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/GOV/9.

Propeller Governors

AD/GOV/9 Governor Control Arm Attachment
Cap Screw A-1635-105 - Replacement 4/2009

Requirement:

CANCELLED.

This AD is cancelled on 9 April 2009.

Background:

This unique Australian AD was raised in 1985 against McCauley Service Bulletin (SB) No. 156 requiring replacement of the propeller governor control arm attachment screw following failures of the screw causing governor control arm to become loose on the control shaft.

Compliance was prior to the issue of the next maintenance release after 31 May 1985.

Given the extended period this AD has been promulgated and that all affected propeller governors would have been modified by now, this AD is considered to be no longer required.
