AIRWORTHINESS DIRECTIVE

DHC-2 (Beaver) Series Aeroplanes

AD/DHC-2/14 Main Undercarriage Lower Forward Attachment - Modification 11/2008

Requirement:

CANCELLED.

This AD is cancelled on 23 October 2008.

Background:

This unique Australian AD, raised in 1967 against Hawker De Havilland Technical News Sheet (TNS) DHC-2 Aust. No.5, required an inspection and modification of the main undercarriage lower forward attachment bolt following reports of failure due fatigue cracking.  Modification was required forthwith.  The inspection of the bolt is the subject of AD/DHC-2/15 which requires a fluorescent penetrant inspection for hard chrome plated bolts.

As all affected aircraft would have been modified by now, this AD is no longer required.
