Plain English Summary

2/10 complexity

This order requires operators of Robinson R22 helicopters (serials 0002–1431 with removable tail-rotor pedals) to inspect and, if needed, remove or repair the tail-rotor pedal retaining clips per Robinson Service Bulletin No. 64, and to install the bulletin’s permanent fix.

Inspections must be done before the next flight after 31 July 1990; the permanent fix by the next maintenance inspection after that date or by 31 December 1990. A clip failure allowed a pedal to slip and partly jam, risking loss of tail control and a crash.
