Plain English Summary

2/10 complexity

What this does This Airworthiness Directive mandates safety-critical maintenance for Schweizer (Hughes) 269 series helicopters. It requires operators to replace specific tail rotor components, conduct inspections, and follow revised assembly procedures exactly as specified in Hughes Service Information Notice N-155.2.

Who it affects Owners and operators of all Schweizer (Hughes) 269 helicopter models listed in the referenced service notice.

What you must do You must complete the specified component replacements, inspections, and assembly updates within 100 hours of flight time ("TIS" means Time In Service) after 31 October 1983—unless you have already performed these actions.

Why it matters This amendment expands the original safety directive to cover additional helicopter models and tail rotor components. The changes ensure critical tail rotor maintenance—which prevents potentially catastrophic mechanical failures—is performed across a broader range of aircraft in this fleet.
