## Summary

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH Helicopters (Airbus Helicopters) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This proposed AD would require installing rivets to the air inlet cover rings (rings). This proposed AD is prompted by reports of rings detaching. The actions of this proposed AD are intended to prevent the unsafe condition on these products.
