## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2021-15-51, which applies to Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) Model 204B, 205A, 205A-1, 205B, and 212 helicopters. AD 2021-15-51 requires removing certain main rotor hub strap pins (pin) from service and prohibits installing them on any helicopter. Since the FAA issued AD 2021-15-51, it was determined that a defective pin could also be installed on Bell Textron Inc. Model 210 helicopters. This proposed AD would continue to require the actions in AD 2021-15-51 and expand the applicability to add Model 210 helicopters. The FAA is proposing this AD to address the unsafe condition on these products.
