## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for Helicopteres Guimbal (HG) Model Cabri G2 helicopters. This proposed AD was prompted by the determination that certain parts need life limits and certification maintenance requirement (CMR) tasks. This proposed AD would require establishing life limits and CMR tasks for various parts and removing any parts from service that have reached or exceeded their life limits. Depending on the results of the CMR tasks, this proposed AD would require corrective action. The FAA is proposing this AD to address the unsafe condition on these products.
