Plain English Summary

2/10 complexity

This directive requires mandatory safety inspections of tail rotor blades on certain Hughes/McDonnell Douglas and Kawasaki 369-series helicopters (specified by serial numbers in Hughes Service Information Notice HN-19.1) to prevent catastrophic tail-rotor failure and loss of control.

Owners/operators must inspect blades either before every flight if the blade had under 100 flight hours as of 10 Feb 1971, or within 10 flight hours if it had over 100; pilots may perform and sign off the inspections.
