Accident Summary:

The pilot and an infantry battalion commander were flying a command and control mission. The pilot was directed to fly a low level visual reconnaissance mission over the Can Giouc River, 18 air miles east of Tan An and 4000 to 5000 meters south of Can Giouc. The pilot was flying at approximately 10 feet above and down the center of the river. He and his passenger were observing both of the heavily foliaged banks of the river in an effort to detect potential ambush sites from which the troop carrying boats, which would soon pass this area, might be ambushed. At this time an M-79 grenade launcher that had been stored by the passenger between the pilot's and passenger's seat fell forward striking the collective which resulted in lowering pitch. This caused the aircraft to abruptly descend. The left skid of the aircraft struck the water ripping it off. The pilot immediately initiated a cyclic climb to prevent the aircraft from rolling with the impact of the strike and regained collective control. The passengers were dropped off at Can Giouc and the aircraft flown to Tan An for repair
