When he opened the door from the outside, the plane was still pressurized enough to force the door outward fast enough to hit the mechanic in the head and kill him.
Also in a King Air, a Co-pilot was removed from the aircraft inadvertently after getting up to investigate a "Cabin Door" light. Upon grabbing the door handle the door popped open and he was pulled out of the aircraft. His arm caught in the door cable (luckily) and he hung out there with the door until the aircraft was landed. Memory items for door light in the King Air are for all occupants to stay seated and seat belt fastened. Seems to me that it wouldn't be too hard...I'm sure a negative pressure valve could fail...its normally just a diaghram, and it likely wouldn't be a known failure until it was tried.
