This directive requires owners/operators of Piper/Ted Smith Aerostar 600/700 series aircraft to retire fatigue-prone parts on fixed schedules to prevent metal-fatigue failures. Compliance is immediate.

Key mandates: retire components per the Piper Aerostar Maintenance Manual limits; for pressurized models (601P/602P/700P) replace cockpit windshields at 3,300 pressurized cycles and cabin windows at 6,600 cycles; replace Hartzell HC‑C4YR propeller blades on Machen‑modified Lycoming engines after 10,500 flight hours.
