AD/BELL 206/78 Freewheeling Outer Race Shaft - Inspection 11/2008

Requirement:	CANCELLED.
This AD is cancelled on 23 October 2008.
Background:	This unique Australian AD, issued in 1979, required  a magnetic particle inspection of the freewheeling outer race shaft in accordance with Bell Alert Service Bulletin 206-78-2 to detect cracking in the radii forward of the engine drive shafts.  The AD compliance was at the next 100 hour inspection and at each freewheeling assembly overhaul.  As the requirements of this AD are now contained in the manufacturer's maintenance and overhaul manual, the AD is no longer required.
