AD/BELL 222/16 - Tail Rotor Boost Cylinder Support Bracket - CANCELLED

This document cancels a previous aviation safety rule that applied to specific Bell helicopters.

What it does:

• Formally cancels Airworthiness Directive AD/BELL 222/16 on 4 August 2005
• Removes a one-time maintenance requirement from 1989 concerning the tail rotor boost cylinder support bracket
• Applies to Bell Helicopter Textron Canada (BHTC) 222 Series Helicopters

Who it affects:

• Owners and operators of Bell 222 series helicopters
• Licensed aircraft maintenance engineers

Why it matters: The original directive required a specific safety action back in 1989. After 16 years, the Civil Aviation Safety Authority (CASA) determined the rule was no longer relevant to current flight safety. Cancelling it removes unnecessary regulatory burden while maintaining safety standards.
