## Summary

This document proposes the adoption of a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters. This proposal would require changes to the electrical power distribution system. This proposal is prompted by design deficiencies in the electrical systems. The actions specified by the proposed AD are intended to prevent failure of both generators, loss of primary electrical power, and subsequent loss of control of the helicopter.
