I'm surprised a blade strike that required removal of all blades didn't also require the removal of the MGB for inspection or overhaul
Agreed, had a strike with a full sheet of thick plywood in a Huey while taxiing down a line of revetments, resulted in a bad vertical, landed immediately, the mast had been twisted some degrees said maintenance. Can only imagine the loading on the gear box teeth. The strike was perpendicular to the full face of the plywood so the loading doesn't bare thinking about.
