Airworthiness Directive · Amendment 39-21883 · Main rotor blades
Leonardo S.p.a. (Type Certificate Previously Held by Agusta S.p.A.) Helicopters
This AD applies to Leonardo S.p.a. (type certificate previously held by Agusta S.p.A.) Model A109A and A109A II helicopters, certificated in any category, with a main rotor (M/R) blade part number 109-0103-01-115 installed.
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. (type certificate previously held by Agusta S.p.A.) Model A109A and A109A II helicopters. This AD was prompted by a report of internal corrosion on a main rotor (M/R) blade. This AD requires repetitively inspecting affected M/R blades and accomplishing film analysis and repair in accordance with certain approved methods. The FAA is issuing this AD to address the unsafe condition on these products.
For each M/R blade identified in paragraph (c) of this AD:
(1) Within 50 hours time-in-service or 3 months after the effective date of this AD, whichever occurs first, unless already done within the last 24 months for the M/R blade, and thereafter, at intervals not to exceed 24 months for the M/R blade, inspect the M/R blade by following the Accomplishment Instructions, paragraphs 1. through 5., of Leonardo Helicopters Alert Service Bulletin No. 109-155, dated March 13, 2020.
(2) Before further flight, send the film for analysis and accomplish repair in accordance with a method approved by the Manager, General Aviation & Rotorcraft Section, International Validation Branch, FAA; or European Union Aviation Safety Agency (EASA); or Leonardo S.p.a Helicopters' EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
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.
