Plain English Summary

3/10 complexity

Operators and maintainers of Eurocopter AS 355 helicopters with specified tail‑rotor blades must follow a mandated inspection programme—set out in the Aerospatiale Workcard—because of reported bonding separation of leading‑edge protectors. Blades under 100 hours face immediate and repeated short‑interval inspections; blades over 100 hours have a one‑off short deadline. The owner/operator bears inspection, repair, downtime and recordkeeping costs.
