Airworthiness Directive · Amendment 39-21817 · Equip/furnishing system wiring
Airbus Helicopters Deutschland GmbH Helicopters
This AD applies to Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2020-0246, dated November 10, 2020 (EASA AD 2020-0246).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. This AD was prompted by a report of chafing marks on a wiring harness near the locking washer of the lateral control rod. This AD requires an inspection of the wiring harness and the routing of the wiring harness and corrective actions if necessary, 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, EASA AD 2020-0246.
(1) Where EASA AD 2020-0246 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2020-0246 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where Paragraph (3) of EASA AD 2020-0246 specifies to update the Aircraft Maintenance Programme (AMP) with certain tasks included in the service information referenced by EASA AD 2020-0246, this AD does not include that requirement.
(4) This AD does not require the “Remarks” section of EASA AD 2020-0246.
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.
