## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Inc. (type certificate previously held by Bell Helicopter Textron Inc.) (Bell) Model 205B helicopters. This proposed AD was prompted by a notification of certain parts needing a life limit. This proposed AD would require determining the total hours time- in-service (TIS) of certain part numbered main rotor grip assemblies (grip assemblies), establishing a life limit for certain part-numbered grip assemblies, removing from service any grip assembly that has reached or exceeded its retirement life, creating a component history card, and removing any grip assembly from service before reaching its retirement life. This proposed AD would also prohibit installing certain grip assemblies unless the life limit was established in accordance with this proposed AD. The FAA is proposing this AD to address the unsafe condition on these products.
