Accident Summary:

At 1725 local, Night Hawk aircraft #66-16840 took off from Cam Rahn Air Force Base to test the Night Hawk system aboard before being released for that mission. At 1732 local, they requested permission to cross Cam Rahn's southern extension of runway 20. At approximately 1736 the transmission "Engine failure, going down at this time!" was heard from the aircraft. The aircraft was flying north board at approximately 100 feet when a left and right yawing occurred and the aircraft started descending. One witness stated it sounded like the engine was running down. At about 25 to 30 feet AGL it was noted that the main rotor had slowed noticeably and the aircraft was in a 30 degree nose high attitude. The aircraft impacted tail stinger/end of tail boom first, leaving an accurate account in the sand. The aircraft next hit slightly nose low with the right skid breaking at the rear crosstube. At this point on the ground there was a 15 degree slope running right to left. The aircraft still had forward momentum and rotated around the nose about 170 degrees clockwise hitting the ground nose low and breaking the tail boom. As the aircraft settled a main rotor blade hit the uphill side at about the 10 o'clock position pulling the transmission right and forward and rolling the aircraft over onto its right side. At what point the aircraft burst into flames is not clear. However it was between the initial impact and the time it finally came to rest. Witnesses stated that no attempt at escape by the crew was observed. The aircraft did not have a crash worthy fuel system. Initial autopsy reports indicate survivable to partially survivable accident without the fire.
