Airworthiness Directive · Amendment 39-21824 · Rotorcraft flight control
Airbus Helicopters
This AD applies to all Airbus Helicopters Model AS355NP helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This AD was prompted by a report of mechanical deformation found on the protective cover (also referred to as switch guard) of the "SHEAR" control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. This AD requires replacement of the protective cover of the "SHEAR" control pushbutton, and re- identification of the pilot collective stick, 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 2021-0027R1, dated January 22, 2021 (EASA AD 2021-0027R1).
(1) Where EASA AD 2021-0027R1 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not require the “Remarks” section of EASA AD 2021-0027R1.
As of the effective date of this AD: Do not perform external load operations until the modification required by Paragraph (1) of EASA AD 2021-0027R1 is complete.
Although the service information referenced in EASA AD 2021-0027R1 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
