## Summary

We propose to adopt a new airworthiness directive (AD) for certain Bell Helicopter Textron Canada Inc. (BHT) Model 206A, 206B, and 206L helicopters. This proposed AD would require replacing certain part-numbered engine auto-relight kit control boxes. This proposed AD is prompted by a design review that revealed the control box chipset did not meet the required temperature range requirements, which could cause the control box to malfunction, disabling the engine auto-relight system. This condition could result in increased pilot workload during a power loss emergency and subsequent loss of control of the aircraft.
