Pre-buy inspection points
Mooney's 100 Hour-Annual guide covers the M20K. Check the lower longerons for corrosion (SB M20-208), turbocharger clamp tightness, unmetered fuel pressure, a hot differential compression test, landing gear shock discs, and the gear-up horn in flight at 14-16 in MP. Bendix magnetos are overhauled each 500 hours/4 years.

Safety notes
- The guide calls for checking the cabin ventilation and heating system for carbon monoxide, and the exhaust system for leaks and cracks.
- An Italian ANSV report covers a 2019 M20K accident (loss of control after a go-around). The supplied excerpt does not state the cause.
- If oxygen is fitted: hydrostatic test the bottle every 3 yrs and overhaul the regulator every 6 yrs. Composite bottles expire at 15 yrs.
