Plain English Summary

5/10 complexity

This Airworthiness Directive requires inspection and corrective action for Honeywell KAP 140 and KFC 225 autopilot systems that use specified KS-series servo actuators (identified by part and serial numbers) in line with the listed Honeywell/AlliedSignal service bulletins. It applies to owners/operators of aircraft fitted with those autopilots (examples include certain Cessna, Commander and Mooney models) and matters because it addresses an identified unsafe condition in servo actuators that can impair autopilot performance.
