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/CESSNA 177/8.

Cessna 177 Series Aeroplanes

AD/CESSNA 177/8 Control Systems 2/2008

Requirement:	CANCELLED.
This AD is cancelled on 14 February 2008.
Background:	This is a unique Australian AD issued in 1970 requiring a once off replacement of a number of NAS 679 lock nuts installed on Cessna aircraft between April and November in 1969.  These nuts were suspected to have a manufacturing flaw.  As all nuts would have now been replaced, the unsafe condition no longer exists.
