Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Robinson Helicopter Company (Robinson) Model R44 helicopters. This proposal would require removing and replacing the cyclic control pilot's grip assembly (grip assembly) with an airworthy grip assembly. This proposal is prompted by a report of a crack in the welded corner of a grip assembly. The actions specified by the proposed AD are intended to prevent use of a grip assembly that may crack, resulting in failure of the grip assembly and subsequent loss of control of the helicopter.
