Plain English Summary

2/10 complexity

This AD requires owners/operators and maintenance organisations to inspect Fairey metal propeller hub retaining nuts for tightness within 5 hours after installation and thereafter at intervals not exceeding 100 hours TIS. It aims to reduce risk of nut loosening, but places recurring inspection costs and downtime on operators. The AD sets timing only, leaving inspection method, pass/fail criteria and record-keeping to operators, creating possible implementation variability.
