Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AW119 MKII helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2021-0040, dated January 27, 2021 (EASA AD 2021-0040).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW119 MKII helicopters. This AD was prompted by reports of detected smoke and burning smell during flight, caused by chafing of electrical wiring. This AD requires an inspection of the instrument panel electrical wiring, corrective actions if necessary, a modification of the wiring installation, and, for certain helicopters, an additional modification of the wiring installation, 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.

(8) Where the service information referenced in EASA AD 2021-0040 specifies to contact Leonardo if the cargo hoist indicator cable is damaged, this AD requires repair or replacement using a method approved by the Manager, International Validation Branch, FAA. The Manager's approval letter must specifically refer to this AD.
