## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model A109E, A109S, AW109SP, A119, and AW119 MKII helicopters. This AD was prompted by a report that certain manufacturer maintenance instructions for swashplate assembly installation specified incorrect torque values for certain swashplate nuts. This AD requires repetitively inspecting certain swashplate nuts for cracks, fretting, or slippage marks and, depending on the results, performing corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
