## Summary

We propose to adopt a new airworthiness directive (AD) for the Brantly International, Inc. (Brantly) Model B-2, Model B-2A, and Model B-2B helicopters with a certain main rotor blade. This proposed AD was prompted by multiple reports of main rotor (M/R) blade cracks and an accident in which a crack that originated near the M/R blade trailing edge resulted in the loss of a large section of the M/R blade. The proposed actions are intended to prevent loss of the M/R blade and subsequent loss of control of the helicopter.
