AD/HU 369/26 Main Rotor Pitch Link Bolts
and Nuts - Inspection 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. HN-108 required a one-time inspection to ensure that proper and compatible attach bolts and nuts were used to secure the pitch control rods to the pitch housing assembly.  Information given in the SIN is now part of Basic Handbook of Maintenance Instructions (HMI) and IPC.

Compliance was:  Within 100 hours TIS after 31 March 1977.

Given that the requirements of this AD are contained in the HMI and IPC; this AD is considered to be no longer required.
