Plain English Summary

4/10 complexity

This Airworthiness Directive requires owners of certain Cessna 172R and 172S aeroplanes fitted with Honeywell KAP 140 autopilot computer systems (specific part numbers and serial-number ranges) to install an operating‑software update. CASA issued the AD and the update must be installed in accordance with the AD's instructions.

CASA says the update is intended to prevent unintentional autopilot engagement that could cause a pilot to take inappropriate actions. The compliance cost and installation work fall to aircraft owners/operators (usually through authorised maintenance or avionics personnel); the Directive also adds four KAP 140 part numbers omitted from an earlier FAA AD.

AD/CESSNA 170/74 (continued)

However, when issuing AD 2003-24-13 the FAA inadvertently omitted four part numbers from the applicability that was reflected in AD/CESSNA 170/73. This Directive, whilst not superseding AD/CESSNA 170/73, complements that Directive by listing the omitted KAP 140 autopilot computer system part numbers.

This Directive requires the installation of an update to the operating software of the KAP 140 autopilot computer system. This action is intended to prevent unintentional engagement of the KAP 140 autopilot computer system, which could cause the pilot to take inappropriate actions.
