This Airworthiness Directive requires operators of specified Ted Smith / Piper Aerostar 600, 601, 601P, 602P and 700P aeroplanes (S/Ns listed in Piper Mandatory SB 908) to inspect and rig cabin doors and latches, install door placards, fit a door-ajar warning (or a CASA‑approved equivalent) and, for certain serial ranges, install a door linkage kit. Compliance is tied to 100 hours time‑in‑service or the next maintenance release, with recurring inspections. CASA cites overseas incidents of unlatched doors as the reason; operators pay for inspections, modifications and any approvals.
