Narrative:
Main gear actuator was raised with hoist equipment up to wing level. Tooling that held actuator to hoist failed. The bolt that held hoist swivel link between hoist and actuator clamp came off. Actuator fell 12 feet to ground and almost struck several personnel. Luckily no one was injured. Upon further investigation; the bolt that held the hoist swivel link came loose and fell out. The bolt has only 4 threads to hold the weight of the actuator and there is no locking device to prevent bolt from coming out.
