AIRWORTHINESS DIRECTIVE

Bell Helicopter Textron 47 (All Variants) Series Helicopters

AD/BELL 47/82 Amdt 1 Tail Rotor Drive and Fan Drive Bearings 2/2009

Requirement:	CANCELLED.
This AD is cancelled on 12 February 2009.
Background:	This unique Australian AD, issued in 1980, required replacement of the tail rotor drive and fan drive bearings in accordance with Bell Alert Service Bulletin 47-80-6.  The AD compliance was within 600 hours time in service after 30 October 1980.  As all aircraft would have replaced the bearings by now, the AD is no longer required.
