Plain English Summary

4/10 complexity

This airworthiness directive requires Model S-62A helicopters fitted with part S14-40-2415 primary servo mechanism supports to undergo specified inspections (including fluorescent magnetic particle inspection) at set intervals and at gearbox overhaul/1,250 flight hours. It responds to a reported fracture in a support fitting and a fractured retaining bolt. Owners/operators must schedule initial and recurring inspections (initial within and thereafter every 120 flight hours) and pay for any repairs; the Civil Aviation Safety Authority enforces compliance.
