McDonnell Douglas (Hughes) and Kawasaki 369 Series Helicopters

AD/HU 369/52 Attachment Hardware for Sta-Strap
Securing Electric Wiring to Boom
Fairing at Sta 138.50 - Inspection 6/2009

Requirement:

CANCELLED.

This AD is cancelled on 4 June 2009.

Background:

This AD, raised in 1981 against Hughes Service Information Notice (SIN) No.
DN-96, required a one-time inspection to ensure that a steel washer had not been inadvertently installed under the aluminium rivet securing the sta-strap securing electrical wiring to the boom fairing at STA 138.50.  Compliance was required within100 hours TIS after 31 December 1981.

As all affected aircraft would have been inspected, and, if necessary, modified long ago, this AD is no longer required.
