Plain English Summary

2/10 complexity

Owners and maintenance organisations of CA25 (Skyfox/Hedaro) aeroplanes must inspect the rear air‑filter‑box mounting rivets and replace any loose/broken/missing pop rivets with specified MS20470 solid rivets, and at the next maintenance release (or within 100 flight hours) remove the box and replace all rear mounting pop rivets with solid rivets. The AD addresses a safety risk that pop rivets can work loose and be ingested into the engine; owners/operators pay and licensed maintainers must perform the work.
