The Bell MGB design use a long shaft that affords the ability of the Gear Box to provide a Load Path that works to transfer loading when gears begin to break apart. I am curious about the basic differences between the new designs as compared to the older designs in that regard.
I wonder what the statistics are on MGB failures in Legacy Aircraft are as compared to "new" design Gearboxes.....particularly in Catastrophic failures that result in the loss of the aircraft and its occupants.
