## Abstract

We are publishing a new airworthiness directive (AD) for Agusta Model A109A and A109A II helicopters, which was sent previously to all known U.S. owners and operators of these helicopters. This AD requires replacing a certain part-numbered blade with an approved part- numbered blade. This AD is prompted by an error in the Illustrated Parts Catalog (IPC) that incorrectly allows installation of a certain part-numbered blade on the affected helicopters. These actions are intended to prevent blade failure and subsequent loss of control of the helicopter.
