AD/HU 369/50 Main Rotor Hub Strap Pack Retention Bolts and Bushings Inspection and 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 369/50.

McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters

AD/HU 369/50 Main Rotor Hub Strap Pack Retention Bolts and Bushings - Inspection and Replacement 6/2009

Requirement:

CANCELLED.

This AD is cancelled on 4 June 2009.

Background:

This unique Australian AD raised in 1981 against Hughes Service Information Notice (SIN) No. DN-91 required an inspection for corrosion of the main rotor hub strap retention bolts and bushings that may have occurred since installation.

Compliance was:  Within100 hours TIS after 30 September 1981, unless already accomplished within the last 200 hours TIS.

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.
