Plain English Summary

2/10 complexity

This AD requires owners/operators of Aerostar 600/700 series aircraft with airframe sequence numbers below 0660 to modify the engine nacelle drain tubes per Piper SB600-80 Part II or FAA AD 79-08-05. Work must be completed within 100 hours TIS after 30 June 1979. The change reduces the risk that wing-tank fuel will collect in the lower nacelle aft of the firewall and ignite on engine start. Costs and downtime fall to owners/operators.
