Propellers - Variable Pitch - Hartzell

AD/PHZL/77 Amdt 2 Australian Air Props 5/2009

Requirement:

CANCELLED.

This AD is cancelled on 7 May 2009.

Background:

This unique Australian AD was raised in 2003 required an inspection of propeller hubs Hartzell propellers released by Australian Air Props Pty Ltd following propeller strike during the period 1 January 1991 to 31 December 1996 due to possible machining of the preload plate shelf being contrary to Hartzell Standard Practices Manual 202A.

Compliance was inspection within 50 flight hours or six months from 15 May 2003 and dismantling before return to service.  Remove from service any hub found to be incorrectly machined and report results to CASA.

This AD has been found to have been adequately addressed; therefore this AD is considered to be no longer required.
