Plain English Summary

1/10 complexity

This document officially cancels a previous safety rule (Airworthiness Directive AD/R44/1) that applied to Robinson R44 helicopters.

What the old rule required: The original 1994 directive mandated that owners inspect the helicopter's cooling fan wheel every 25 flight hours. This inspection had to continue until the fan was replaced with an upgraded part (specifically part number D174-1 at Revision G or later).

What this document does: It removes that inspection requirement entirely. Owners no longer need to perform these 25-hour checks or comply with the old directive.

Who is affected: Owners and operators of Robinson R44 Series Helicopters who were previously subject to the fan inspection requirement.
