Gippsland Aeronautics GA8 Series Aeroplanes

AD/GA8/3 Amdt 2 Forward Cargo Door Slide 16/2010

Applicability:

GA8 - all serial numbers.

Requirement:

Accomplish the requirements of Gippsland Aeronautics mandatory service bulletin SB-GA8-2005-23 Issue 3, dated 5 August 2010.

Compliance:

As specified in the requirement document, with an effective date of 17 August 2010.

This Amendment becomes effective on 17 August 2010.

Background:

Inspections have revealed cases of excessive wear in the forward slide of the cargo door.  Excessive wear in the door slide may result in the door becoming detached from the aircraft in flight, with potentially catastrophic results.

Following a recent in-flight door separation, this amendment is issued to update the service bulletin to remove any ambiguities that could have existed in the previous revision to the referenced service bulletin.  It also provides an improved inspection method and a minor design change to the cargo door slide (inclusion of slide backing plate, castellated nut and spilt pin).
