Plain English Summary

2/10 complexity

This airworthiness directive requires owners/operators to have specific automatic‑pilot servo actuators inspected (limited by model, serial‑number ranges and absence of a white dot) within 100 hours TIS after 28 June 1974, using one of the referenced Cessna/FAA procedures. Maintenance providers carry out the work; costs and downtime fall to the aircraft owner/operator. CASA mandates and enforces the requirement, while the referenced service documents govern the technical inspection and any corrective actions.
