Plain English Summary

2/10 complexity

This Airworthiness Directive requires operators of Cessna 401/402 aeroplanes to retire four specified exhaust manifold tube assemblies by fixed hours-in-service limits, with earlier deadlines for assemblies already over the threshold. It forces operators to check part service hours, schedule replacements, and bear the immediate operational and financial burden of removal and replacement, tightening maintenance and record-keeping to ensure compliance.
