Airbus Helicopters is proposing a new solution to prevent delamination of engine mount bushings, thus improving their reliability.

The solution consists of a new engine bushing made of steel mesh that can be installed without any modification to the engine mounts, in approximately 8 hours.

As a result, the 50 Flight Hours repetitive inspections will no longer be required once a bushing is replaced. Currently applicable to the BK117 D-2, this solution will be extended to BK117 C-2 in 2019.

This improvement is a part of the 2018 Top irritant resolution program for H145.

Detailed information is available through ASB MBB-BK117 D-2-71A-002 and all the necessary parts can be ordered through P/N SB-117D2-71A-002-2C material kit.
