What it does

The FAA proposes to supersede Airworthiness Directive (AD) 2024-18-01, which applies to Leonardo S.p.A. Model A119 and AW119 MKII helicopters. AD 2024-18-01 requires repetitive inspections of certain collective stick torque tube assemblies for deficiencies and corrective action, as applicable. Since the FAA issued AD 2024-18-01, an improved collective stick torque tube assembly was designed, and replacement instructions were issued. This proposed AD would require repetitive inspections of certain collective stick torque tube assemblies and, depending on the results of the inspection, replacement of affected parts. This proposed AD would also require modification of the helicopter through replacement of an affected part with a serviceable part, which would constitute terminating action for the repetitive inspections. This proposed AD would also prohibit installation of an affected part on any helicopter. The FAA is proposing this airworthiness directive (AD) to address the unsafe condition on these products.
