The directive applies to all serial numbers of the MBB-BK117 D-2 helicopter variants.
What changed
EASA Airworthiness Directive 2025-0153 introduces a mandatory modification of the CCHB and fuel system on affected MBB-BK117 D-2 helicopters to mitigate the risk of fuel leakage following survivable accidents. It requires compliance with Airbus Helicopters Alert Service Bulletin MBB-BK117-25-98-0003 and related service bulletins. The directive also prohibits the installation of the affected CCHB part number L851M1301101 without modification.
Why it matters
