Helicopter gearbox failures are guaranteed to cause the loss of the helicopter.[^1] Unlike in an autorotation, if the gearbox fails, the rotor stops spinning and the helicopter falls out of the sky.[^1] If the pilots are alerted prior to the failure, they can perform a forced landing maneuver before the rotor seizes.[^1]
