Ad/Cessna 177/15 - Vertical Fin Forward Attachment Bulkhead - 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/CESSNA 177/15.

Cessna 177 Series Aeroplanes

AD/CESSNA 177/15 Vertical Fin Forward
Attachment Bulkhead 10/2008

Requirement:

CANCELLED.

This AD is cancelled on 25 September 2008.

Background:

This unique Australian AD, raised in 1974 against Cessna Service Letter (SL) No. SE73-40, required an inspection for possible cracking of the vertical fin forward attachment bulkhead.  If cracks were found it was necessary to replace the bulkhead assembly with one of an improved design.

Compliance was within 100 hours TIS after 28 February 1974 and thereafter at intervals not exceeding 100 hours TIS until replaced with the improved bulkhead.  As all affected aircraft would have been inspected and modified by now, this AD is no longer required.
