Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes

AD/TSA-600/34 Hydraulic System Internal Leak Check 6/2009

Requirement:	CANCELLED.
This AD is cancelled on 4 June 2009.
Background:	This unique Australian AD specified that each aircraft not fitted with an auxiliary hydraulic pump system was to be placed on jacks, and the landing gear checked to ensure it remained fully retracted for 30 minutes with hydraulic pressure selected off.  The inspection was not based on a service document and was required at each maintenance release inspection.  The absence of service difficulty reports indicates this inspection should no longer be the subject of an AD.
