AD/HU 369/30 Main Rotor Pitch Control Rod Replacement 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 369/30.

McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters

AD/HU 369/30 Main Rotor Pitch Control Rod - Replacement 6/2009

Requirement:

CANCELLED.

This AD is cancelled on 4 June 2009.

Background:

This unique Australian AD raised in 1977 against Hughes Service Information Notice (SIN) No. DN-6 required a modification by replacing existing main rotor pitch rod with a new and shorter rod to preclude interference between the pitch rod end and arm of pitch housing assembly, and an inspection of upper and lower rod ends to ensure serviceability of the rod end bearing.

Compliance was:  Within 100 hours TIS after 30 November 1977.

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