Airworthiness Directive · Amendment 39-21979 · Cabin equipment/furnishings
Airbus Helicopters Deutschland GmbH (AHD) Helicopters
This AD applies to Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters, certificated in any category, modified by Supplemental Type Certificate (STC) SR03130NY, or STC SR03703NY.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This AD was prompted by a report of erroneous or partial installation of the seat belt restraint system. This AD requires inspecting certain seats, 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 2021-0287, dated December 21, 2021, and corrected January 26, 2022 (EASA AD 2021-0287).
(1) Where EASA AD 2021-0287 requires compliance in terms of flight hours, this AD requires using hours time-in-service (TIS).
(2) Where EASA AD 2021-0287 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where paragraph (1) of EASA AD 2021-0287 specifies to “inspect each affected part in accordance with the instructions of the SB,” this AD requires inspecting each affected part by following the procedures in Mecaer Aviation Group Mandatory Service Bulletin No. SB-EC1-010, Revision A, dated December 30, 2021 (SB-EC1-010, Rev A). Except for the purposes of this AD, consider Figure 16 on page 16 of SB-EC1-010, Rev A, as Figure 18 and consider Figures 17 and 18 on page 17 of SB-EC1-010, Rev A, as Figures 19 and 20, respectively.
Note 1 to paragraph (h)(3): SB-EC1-010, Rev A refers to a passenger seat as a passenger seat and passenger cabin seat; a seat belt as a seat belt and safety belt; and a bolt as a hex head screw and hex head bolt.
(4) Where the service information referenced in paragraph (2) of EASA AD 2021-0287 specifies to “contact MAG to receive missing parts/materials, if any,” this AD requires replacing the missing parts and materials but does not require contacting MAG to receive the missing parts or materials.
(5) Where the service information referenced in paragraph (2) of EASA AD 2021-0287 specifies contacting “MAG DOA (caw@mecaer.com) to receive instructions,” this AD requires repair done in accordance with a method approved by the Manager, General Aviation & Rotorcraft Section, International Validation Branch, FAA; or EASA; or Airbus Helicopters' EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(6) Where the service information referenced in paragraph (2) of EASA AD 2021-0287 specifies, “17. Make available items C (q.ty 2) and D (q.ty 2) (ref. Figure 18), for each affected seat,” this AD requires installing new (zero total hours TIS) nuts and hex head screws.
(7) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0287.
Although the service information referenced in EASA AD 2021-0287 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.
