## Summary

We propose to adopt a new airworthiness directive (AD) for Robinson Helicopter Company (Robinson) Model R44 and R44 II helicopters equipped with emergency floats, which would require replacing the inflation valve assembly. The proposed AD is prompted by failure of the emergency floats to deploy during a factory test because a needle was binding within the inflation valve assembly. The proposed actions are intended to prevent the failure of the floats to inflate during an emergency landing.
