Plain English Summary

2/10 complexity

This is a mandatory safety check (called an Airworthiness Directive) for owners of Schweizer (Hughes) 269A and 269B helicopters. What you must do: Visually inspect the tail boom (the long strut at the back of the chopper) for cracks around two specific bolt locations — where the tail rotor gearbox attaches, and where the horizontal stabiliser bolts on. Who it affects: Anyone operating these specific helicopter models. When: Every 50 hours of flight time, starting from 13 May 1966. Why it matters: Cracks at these high-stress points could cause the tail boom to snap off in flight, which is generally considered catastrophic for continued aircraft operation.
