Requires removing and replacing the pilot's cyclic control grip assembly (grip assembly) with an airworthy grip assembly.

Full official abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to Robinson Model R44 helicopters, that currently requires removing and replacing the pilot's cyclic control grip assembly (grip assembly) with an airworthy grip assembly. This amendment requires the same actions as the current AD but would change a part number (P/N) referenced in the current AD. This amendment is prompted by the discovery of an error in the P/N of the current AD. The actions specified by this 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.
