AD/BELL 212/44 - Swashplate Outer Ring - CANCELLED

What this does: This document officially cancels an old aviation safety rule (Airworthiness Directive 44) that previously required owners of Bell 212 helicopters to inspect a specific part called the "swashplate outer ring" for dangerous manufacturing defects.

Who it affects: Owners and operators of Bell Helicopter Textron 212 series helicopters — though in practice, this is purely administrative "housekeeping." The original inspection had to be completed by May 1990, so all affected aircraft were inspected decades ago.

Why it matters: The original rule was issued in 1990 to identify casting defects in swashplates (a critical component that helps control the helicopter's rotor blades). Because the compliance deadline passed nearly 20 years prior to this cancellation, the requirement is redundant. This instrument simply removes the obsolete rule from the books to keep the aviation safety regulations current and uncluttered.
