Airworthiness Directive · Amendment 39-23343 · Leonardo S.p.a. Helicopters
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. AB139, AW139, AW189.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.a. Model AB139, AW139, and AW189 helicopters. This AD was prompted by a report of cracks on the left-hand (LH) and right-hand (RH) tube assemblies installed on the brake pedal assemblies. This AD requires repetitively inspecting the LH and RH tube assemblies for Model AB139 and AW139 helicopters, and the LH and RH pedal shaft assemblies for Model AW189 helicopters, and depending on the results of the inspection, corrective actions. This AD also prohibits installing certain parts unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
