## Summary

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This proposed AD would require altering and re-identifying the overhead panel shock mount assembly (shock mount). This proposed AD is prompted by the manufacturer's stress recalculations. The actions of this proposed AD are intended to correct an unsafe condition on these products.
