Plain English Summary

3/10 complexity

This airworthiness directive mandates that operators of specified Cessna 400/401/402/414/421 series aeroplanes inspect engine exhaust assemblies and certain components and replace listed multi‑segment ‘V’‑band exhaust clamps in accordance with the cited Cessna Service Instructions. Inspections are required at 50‑ or 100‑hour intervals depending on the task, and clamp replacement at 750 hours. The directive binds aircraft owners/operators and maintenance providers, who pay for inspections, parts and scheduling; it narrows applicability by excluding the 421C because that model has a modified exhaust.
