## Summary

We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Inc. (Bell) Model 212, Model 412, and Model 412EP helicopters. This proposed AD would require replacing the emergency flotation system (EFS) tube assembly. This proposed AD is prompted by a report of an EFS tube assembly failure. The actions of this proposed AD are intended to address an unsafe condition on these helicopters.
