Accident Summary:
On 27 September 1968, the aircraft was the flight lead of a light fire team which was to return to Dong Ba Thin, RVN from the company forward base at Bao Loc, RVN. Approximately 30 minutes prior to the scheduled departure to Dong Ba Thin, aircraft 120 and crew had returned from a mission in the Dalat area. Upon termination of this mission, the aircraft was refueled with 800 pounds of fuel. During the landing made for refueling, the airfield advisory reported the winds to be 4 to 6 knots from 250 degrees. The aircraft proceeded from the refueling point to parking in the forward base area which is located approximately 1 mile southwest of Bao Loc Airfield and shut down. At approximately 1640 hours, 120 was preparing to return to Dong Ba Thin. The aircraft was piloted by 1LT Wolkman and the aircraft commander was 1LT Heitman. After a normal start, the aircraft was hovered laterally out of the parking revetment to the center of the takeoff lane. The pilot was at the controls. During this hovering maneuver the RPM was noted to bleed off to approximately 6000 RPM. The loss of RPM was attributed to the fact that the aircraft commander LT Heitman, had pushed left pedal during the sideward hover to attempt to observe the progress in preparing to depart of his wing aircraft. Aircraft 120 was set down in the take off lane and when the wing man reported he was ready, take off was initiated. As 120 broke ground and started forward movement, the RPM was noted to decay to approximately 6200 RPM. The take off was continued with approximately 9 inches of ground clearance maintained. Approximately 100 feet forward of the take off point, a muddy, rutted area existed was a vehicle traffic lane which crossed the takeoff lane. As the aircraft reached this area, the aircraft commander, LT Heitman abruptly applied additional collective pitch to clear this area. The RPM was noted to be approximately 5800 RPM after clearing the muddy road. At this time the aircraft commander took control of the aircraft and continued the attempted take off. Approximately 300 feet forward of the muddy roadway another obstacle, a two strand concertina fence, was encountered. This obstacle was cleared at the expense of an additional 200 RPM. Ground contact was made approximately 40 feet past the fence and the aircraft bounced airborne again. Ground contact was again made approximately 60 feet forward. The aircraft again bounced and commenced to spin in a clockwise direction due to a lack of anti-torque control attributed to the low RPM. The aircraft then hit the ground a third time after turning approximately 180 degrees. The main rotor blade struck the ground and a dense brushy area on the left side of the aircraft. The aircraft rolled on its left side at approximately a 45 degree angle and came to rest
