What to do
Operators of Group 1 MBB-BK117 C-2 helicopters must modify the equipment rack extension within 60 days of the AD's effective date following Aerolite AG Alert Service Bulletin instructions. Installation of affected parts is prohibited on Group 1 helicopters after modification and on Group 2 helicopters from the effective date. Compliance can be credited if the modification was done previously according to earlier revisions of the specified service bulletins.
Summary
EASA Airworthiness Directive 2024-0222 is a corrective directive addressing the modification of equipment rack extension support rails installed on MBB-BK117 C-2 helicopters modified by specific Aerolite AG Supplemental Type Certificates. The directive targets certain support tubes and fork fittings associated with equipment rack extensions to ensure continued airworthiness. It applies to all serial numbers of the MBB-BK117 C-2 helicopter modified by the listed STCs.
What changed
This directive introduces a mandatory modification to the equipment rack extension support rails to correct a design deficiency that could lead to failure of the equipment rack extension. It also prohibits installation of affected parts on helicopters unless the modification has been accomplished. The document republishes the AD to correct typographical errors in the reference publications section.
Why it matters
This AD is critical for aviation professionals because it addresses a structural weakness that could compromise the safety of helicopter occupants. Operators and maintenance organizations must ensure compliance to prevent potential equipment rack failure, which could lead to injury. Compliance with this AD is essential to maintain the airworthiness and operational safety of affected helicopters.
