Airworthiness Directive · Amendment 39-23106 · Tail rotor blades
Airbus Helicopters
This AD applies to Airbus Helicopters Model EC 130 B4 and EC 130 T2 helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 130 B4 and EC 130 T2 helicopters. This AD was prompted by the determination that fatigue cracks may develop at the root section of certain tail rotor blades (TRBs). This AD requires inspecting those TRBs and, depending on the results, replacing the TRB with a serviceable TRB. This AD also prohibits installing those TRBs unless certain actions are accomplished. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2022-0150, dated July 21, 2022 (EASA AD 2022-0150).
(1) Where EASA AD 2022-0150 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2022-0150 refers to its effective date, this AD requires using the effective date of this AD.
(3) This AD does not adopt the “Remarks” section of EASA AD 2022-0150.
Although the service information referenced in EASA AD 2022-0150 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
