AD/DHC-1/16 Tailwheel Yoke Attachment Bolt - Inspection 11/2008

Requirement:

CANCELLED.

This AD is cancelled on 23 October 2008.

Background:

This unique Australian AD, raised in 1966, against Hawker Siddeley Technical News Sheet (TNS) Series ST(CI) No. 152, required an inspection of the special attachment bolt Part No. CI-2O.U.T.9, which attaches the tailwheel yolk to the pick-up fitting on the rear bulkhead, for cracking.  Compliance was required at intervals not exceeding 300 hours TIS.

As this AD has been extant for a very long time and no relevant defects have been recorded in the mandatory reporting system, this AD is no longer required.

Delegate of the Civil Aviation Safety Authority
