Stabbing Board Maintenance Failure

The IP first tested the upward function of the board by hoisting the carriage up a couple of feet. When attempting to move the carriage back down, the Sky Locks engaged (still under investigation).

Inadvertently the IP looked up at the hoist and operated the throttle down thinking the hoist was the problem, causing the slack arm to strike against his right hand placed on the vertical pole.

The IP was operating the controls with his left hand. His right hand was placed “naturally” and unconsciously on the nearby framework of the carriage, with his fingers up underneath the Slack Arm position.

The IP made his way to the sickbay via the control room for treatment. The IP was transported onshore the following day, and underwent surgery where the tip of his right middle finger, above the first joint, was amputated.
