Airworthiness Directive · Amendment 39-21983 · Main rotor drive system
Airbus Helicopters
This AD applies to all Airbus Helicopters Model EC130T2 helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC130T2 helicopters. This AD was prompted by the determination of a certain part needing a life limit and re- identification. This AD requires re-identifying a certain part-numbered engine-to-main gearbox (engine-MGB) coupling shaft, and creating a log card or equivalent record, 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.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2021-0216, dated September 23, 2021 (EASA AD 2021-0216).
(1) Where EASA AD 2021-0216 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2021-0216 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (1) of EASA AD 2021-0216 specifies “in accordance with the instructions of section 3.B of the ASB,” for this AD replace “in accordance with the instructions of section 3.B of the ASB” with “in accordance with the Accomplishment Instructions, paragraphs 3.B.2. through 3.B.2.b. of the of the ASB.”
(4) Where Note 1 of the service information referenced in EASA AD 2021-0216 specifies to contact Airbus Helicopters if you have more than one non-installed engine-MGB coupling shaft, this AD does not require contacting Airbus Helicopters.
(5) Where the service information referenced in EASA AD 2021-0216 specifies to use a vibration scriber to re-identify the engine-MGB coupling shaft, this AD allows the use of equivalent tooling.
(6) Where the service information referenced in EASA AD 2021-0216 specifies creating a log card for the engine-MGB coupling shaft, this AD requires creating a log card or equivalent record.
(7) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0216.
Although the service information referenced in EASA AD 2021-0216 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
