🚁FAA Proposes New Airworthiness Directive for Leonardo Helicopters

The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.a. Model A119 and AW119 MKII helicopters. This proposed AD was prompted by a report of an electrical failure of the starter-generator, due to a rupture of the drive shaft, which resulted in a partial loss of battery power. This proposed AD would require installing a battery discharge detector and revising the existing Rotorcraft Flight Manual (RFM) for the helicopter, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

✈️New FAA Airworthiness Directive for Leonardo Helicopters Compliance

The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139 and AW139 helicopters. This AD was prompted by reports of broken main landing gear (MLG) shock absorber piston rod eye ends. This AD requires repetitively inspecting the MLG shock absorber piston rod eye ends, reporting the results of the inspection, and, depending on the results, replacing the MLG shock absorber assembly. It also prohibits installing certain MLG shock absorber assemblies unless specific requirements are met, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
