According to the operator, during initial climb, the door warning light illuminated, and the crew hatch door opened. The door's forward hinge assembly was then torn from its fuselage mount point along with adjacent aircraft skin, which resulted in substantial damage to the airplane. Postaccident examination of the airplane revealed that the door safety latch, warning system, and door latching mechanism worked properly. The operator reported that it was possible to latch the door with the forward pin in its proper anchor point and with the aft pin outside the airframe with the warning light extinguished. The operator further reported that, after the accident, this was covered in aircrew training and the company standard operating procedures.
