Summary
The FAA proposes to adopt a new airworthiness directive (AD) for Helicopteres Guimbal Model Cabri G2 helicopters with any metal bushing installed on the main rotor (M/R) swashplate guide bellcrank. This proposed AD was prompted by a report of cracks discovered on the M/R scissor link during scheduled maintenance on several helicopters. This proposed AD would require removing all metal bushings from service, visually inspecting the lug bore area and depending on the inspection results, removing certain parts from service and installing certain part-numbered plastic bushings. This proposed AD would also prohibit installing any metal bushing on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
