Plain English Summary

3/10 complexity

This airworthiness directive requires certain Cessna 210M/T210M/P210 aeroplanes with ARC Model 400B autopilot installations to have that autopilot physically disabled (disconnect and secure the roll and pitch actuator connectors) and a visible “AUTO PILOT INOPERATIVE” placard until the aircraft is modified per Cessna SL AV78‑6. It affects owners/operators of the listed serial-numbered aircraft, who bear the maintenance and placarding cost and may need an authorised permit to ferry the aeroplane for the work.
