AD/HU 369/64 Tail Rotor Bellcrank 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/HU 369/64.

McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters

AD/HU 369/64 Tail Rotor Bellcrank 6/2009

Requirement:

CANCELLED.

This AD is cancelled on 4 June 2009.

Background:

This unique Australian AD raised in 1986 against Hughes Service Information Notice (SIN) No. DN-137, EN-25 or FN-13 required an inspection to measure the thickness of the ear at the clevis end of the tail rotor bellcrank.

Compliance was:  Within 100 hours TIS after 28 February 1986 or three months, whichever occurs first for installed items, and for non-installed bellcranks before installation in a helicopter.

This AD has been sufficiently promulgated for the affected aircraft to have been inspected by now; therefore this AD is considered to be no longer required.
