AD/BEECH 90/81 Stabiliser and Fin Moisture Sealing 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/BEECH 90/81.

Beechcraft 90 and 65-90 (King Air) Series Aeroplanes

AD/BEECH 90/81 Stabiliser and Fin Moisture Sealing 8/2008

Requirement:	CANCELLED.
This AD is cancelled on 31 July 2008.
Background:	This unique Australian AD, raised in 1989 against Beechcraft Service Bulletin (SB) No. 2254, required sealing of certain horizontal and dorsal fin openings to prevent potential water contamination and/or freezing of flight control cables and servo mechanisms.  As all affected aircraft would have been modified long ago, this AD is no longer required.
