## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Helicopteres Guimbal Model CABRI G2 helicopters. This proposed AD was prompted by a report that, during scheduled maintenance on two helicopters, cracks were found on a certain main rotor (MR) non-rotating scissor link. This proposed AD would require replacing an affected MR non-rotating scissor link with a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.
