Abstract
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2001-22-51, which was sent previously to all known U.S. owners and operators of Agusta S.p.A. (Agusta) Model A119 helicopters by individual letters. This AD requires removing a certain part-numbered tail rotor blade (blade) on or before accumulating 50 hours time-in-service (TIS). This AD also requires visually or dye penetrant inspecting each blade at specified time intervals and removing any cracked blade before further flight. This AD is prompted by the discovery of a fatigue crack on a blade during an inspection. The actions specified by this AD are intended to prevent failure of a blade and subsequent loss of control of the helicopter.
