Plain English Summary

1/10 complexity

What this requires: Owners and operators of specific Enstrom helicopters must replace the safety washer on the tail rotor pitch link.

Who it affects:

Enstrom F-28A helicopters with serial numbers 03 through 349
Enstrom 280 helicopters with serial numbers 1001 through 1030

What you must do: Replace the safety washer according to Enstrom Service Note No. 0033 within 100 hours of flight time after 31 May 1976.

Why it matters: The tail rotor controls the helicopter's direction. A failed pitch link could cause loss of directional control, potentially leading to an accident. This directive ensures a critical safety component is replaced before it fails.
