FAA finalizes safety rule for Guimbal Cabri G2 helicopters
/ 1 min read
Table of Contents
The Federal Aviation Administration has issued a final airworthiness directive requiring owners and operators of Hélicoptères Guimbal Model Cabri G2 helicopters to inspect the main rotor mast for cracks or corrosion. This action follows an emergency directive issued in May 2026 that addressed the same issue while allowing time for public comment.
Why it matters: This rule addresses a safety hazard where cracks in the main rotor mast could lead to its failure and loss of control. For owners of these specific helicopters, it means mandatory maintenance checks and potential part replacements before further flight. The FAA estimates compliance costs at roughly $797 per helicopter for inspection and minor modifications.
Who it affects
- Owners and operators of Hélicoptères Guimbal Model Cabri G2 helicopters in the U.S.
