Plain English Summary

3/10 complexity

This Airworthiness Directive requires owners/operators of Gippsland Aeronautics GA8 aeroplanes (serial numbers GA8-00-004 to GA8-04-056) to inspect the aileron control system per Mandatory Service Bulletin SB-GA8-2004-11 Issue 2 and, if not modified, to repeat inspections at intervals not exceeding 300 hours. Replacing the original steel aileron control shafts with the bronze shafts specified in the service bulletin ends the repetitive inspection requirement for that side. The measure addresses reported control stiffness and a control lock incident.
