What happened
During the boarding process, a passenger was standing near the aircraft entrance. As she stepped aboard, she inadvertently released the latch mechanism that held the door in the open position. With the latch disengaged, the door swung toward the closed position with significant force.
The moving door struck the back of the passenger's foot. The impact resulted in a severe injury, specifically severing the tendon on her foot. There were no other injuries reported during this incident.
At the time of the event, weather conditions in the area included thunderstorms. Wind reports indicated speeds from the southeast at 15 knots, with gusts reaching 20 knots. These environmental factors were noted but did not directly cause the mechanical failure of the door latch; rather, the injury was a direct result of the door's movement during boarding.
The investigation
The investigation focused on the sequence of events leading to the injury. Investigators examined the door latch mechanism and confirmed that it had been released inadvertently by the passenger. There were no indications of mechanical failure in the door system itself prior to the release.
