Plain English Summary

2/10 complexity

What this is: This is an Airworthiness Directive (AD) — a mandatory safety notice issued by the Civil Aviation Safety Authority (CASA) that legally requires aircraft owners to perform specific maintenance checks.

What it requires: Owners of specific Bell 205A-1 helicopters (serial numbers 30001 to 30169) must inspect the swashplate scissors lever bolts. These are critical metal fasteners in the rotor system that help control the helicopter's blade pitch (the angle of the blades that controls lift and direction).

Who must comply: Anyone operating the specified Bell Helicopter Textron 205 series models.

Deadline: The inspection must be completed within 25 hours of flight time after 16 September 1974.

Important note: The directive references a Bell Service Bulletin (SB No. 205-(04-2)-74-1) for the actual step-by-step inspection instructions — meaning you need that technical document to know exactly how to perform the check.
