## Summary

We propose to adopt a new airworthiness directive (AD) for certain serial numbered Bell Helicopter Textron Canada Limited (BHTC) Model 429 helicopters. This proposed AD would require marking a serial number on life-limited forward spars and actuator fitting assemblies. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
