Plain English Summary

3/10 complexity

This directive requires operators to follow Transport Canada AD CF-98-17 to inspect and ensure correct torque of the main rotor grip and flapping bearing retaining bolts after reports of fatigue cracking. It applies to the helicopters listed (the instrument states “All Model 230 helicopters”) and must be complied with within 10 flight hours after 30 August 2007. Operators must schedule and pay for the inspections/maintenance; the Civil Aviation Safety Authority enforces the requirement.
