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 369/10.

McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters

AD/HU 369/10 Main Transmission P/N 369A5100
Series - Modification 5/2009

Requirement:

CANCELLED.

This AD is cancelled on 7 May 2009.

Background:

This unique Australian AD raised in 1973 against Hughes Service Information Notice (SIN) No. HN-56 required a modification to the main transmission assembly by installation of new ring gear bolts and adding identifying letter "B" to the transmission S/No. plate to denote incorporation of new 369A5174 bolts.

Compliance was:  Within 300 hour TIS after 1 November 1973.

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