Airworthiness Directive 2022-26253
one-timeAirworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) (Type Certificates Previously Held by Messerschmitt-Bolkow-Blohm (MBB), and Eurocopter Deutschland GmbH (ECD)) Helicopters
What this AD requires
The FAA is superseding airworthiness directive (AD) 77-04-06, which applied to Messerschmitt-Bolkow-Blohm (MBB) (now Airbus Helicopters Deutschland GmbH (AHD)) Model BO-105A and BO-105 C helicopters; AD 2002-13-06, which applied to certain Eurocopter Deutschland GmbH (ECD) (now Airbus Helicopters Deutschland GmbH (AHD)) Model BO-105A, BO-105C, BO-105 C-2, BO-105 CB-2, BO-105 CB-4, BO-105 CS-2, BO-105 CBS-2, BO-105S, and BO-105LS A-1 helicopters; AD 2016-25- 14, which applied to certain Airbus Helicopters Deutschland GmbH (AHD) Model BO-105LS A-3 helicopters; and AD 2021-10-14, which applied to certain Airbus Helicopters Deutschland GmbH (AHD) Model BO-105A, BO- 105C, BO-105S, and BO-105LS A-3 helicopters. Since the FAA issued those ADs, new and more restrictive airworthiness limitations have been issued. This AD requires incorporating into existing maintenance records requirements (airworthiness limitations) as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of certain part- numbered tension-torsion (TT) straps. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2022-26253 applies to
Type certificates previously held by Messerschmitt-Bolkow-Blohm (MBB) and Eurocopter Deutschland GmbH (ECD). Includes BO-105LS A-3 helicopters modified in accordance with Supplemental Type Certificate SR00043RD.
Whether AD 2022-26253 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
Supersession
Supersedes AD 77-04-06.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
