Plain English Summary

2/10 complexity

This instrument requires every British Aerospace (Scottish Aviation) Twin Pioneer aircraft to be modified, per Scottish Aviation MNS No 965, to eliminate fretting where the wing lift strut meets the stabilizer fitting.

Owners/operators must obtain and pay for the modification (document, parts, labour, downtime); the Civil Aviation Safety Authority will withhold a Certificate of Airworthiness until the work is completed, creating a strong compliance incentive.
