Airworthiness Directive · Amendment 39-21484 · Rotorcraft flight control
Airbus Helicopters
This AD applies to all Airbus Helicopters Model EC 155B and EC155B1 helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155B and EC155B1 helicopters. This AD was prompted by a report of mechanical deformation of the protective cover of the "SHEAR" control pushbutton on the copilot collective stick. This AD requires replacement of the protective cover of the "SHEAR" control pushbutton on the pilot and copilot collective sticks and re- identification of the pilot and copilot collective sticks, 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 2019-0246, dated October 1, 2019 (EASA AD 2019-0246).
(1) Where EASA AD 2019-0246 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2019-0246 does not apply to this AD.
(3) Where the service information referenced in EASA AD 2019-0246 specifies to use tooling, equivalent tooling may be used.
(4) Where paragraph (1) of EASA AD 2019-0246 refers to a table for the compliance time for the modification, for this AD, the compliance time for the modification is before the first hoist operation done after the effective date of this AD but no later than 3 months after the effective date of this AD.
(5) Although the service information referenced in EASA 2019-0246 specifies to discard certain parts, this AD does not include that requirement.
