Analysis

The acft propeller struck a 12 year old male passenger after he deplaned. The accident occurred on an unlighted ramp at about 1930 hours MST. The boy had walked forward along the fuselage to look into the cockpit when he was hit. His father was in the cockpits left seat. The shutdown of engines had been slow the plt said because this was basically a training mission. The left propeller was windmilling to a stop when the boy was hit. According to the line crews this boy was known to jump out the acft and run around the ramp. The company president who was the acting plt at the time of the accident said 'the boy exited the acft against instructions and verbal warnings.'
