Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW169 helicopters. This AD was prompted by reports of failed nose landing gear (NLG) retraction actuators during the acceptance test procedures on the ground on the final assembly line. This AD requires depending on the helicopter configuration, various modifications, installation checks, inspections of the NLG and main landing gear (MLG) retraction actuators and of the plungers of the NLG and MLG up down lock actuators, and corrective actions if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
