## Summary

We propose to adopt a new airworthiness directive (AD) for Robinson Helicopter Company (Robinson) Model R44 and R44 II helicopters. This proposed AD would require visually checking each tail rotor blade for a crack. This proposed AD is prompted by a report of cracking in certain tail rotor blades. The actions of this proposed AD are intended to address an unsafe condition on these products.
