Circumstances:
Following an uneventful flight from Davison AAF (Fort Belvoir), the aircraft was approaching Patuxent River NAS when, at a height of about 800 feet, the aircraft entered an uncontrolled descent and crashed in the Chesapeake Bay. The wreckage sank by a depth of 45 feet and was found less than 100 yards offshore. All five crew members were killed. The aircraft was operated by the US Army Intelligence and Security Command (INSCOM) and carried both civil N296CA and military 88-0321 registrations.
Probable cause:
It was determined that the crew mistakenly selected beta range on the propellers on final approach at an altitude of 800 feet, causing the aircraft to enter an uncontrolled descent.

Circumstances:
The two aircraft, a Beech U-21A and a Piper PA-31-350, collided nearly head on at 7,000 feet msl over Independence, MO. In daylight VMC conditions with a visibility of 20 miles. The U-21 was in level cruise and the PA-31 was climbing eastbound to an undisclosed altitude enroute to Saint Louis. Both aircraft were equipped with operating mode-c transponders but the controller in contact with the U-21 did not observe the conflict and traffic advisories were not provided. The PA-31 was operating in accordance with visual flight rules. The U-21 was operating in accordance with instrument flight rules. After the collision both aircraft crashed in uncontrolled descent. There was no indication that either aircraft took any evasive action. The conflict alert subprogram of the ARTS III tracking system was not programmed to alert the controllers to the impending collision and the two controllers did not observe any target in the vicinity of the data block representing the U-21. All six occupants in both aircraft were killed.
Probable cause:
The National Transportation Safety Board determines that the probable cause of the accident was the failure of the radar controllers to detect the conflict and to issue traffic advisories or a safety alert to the flightcrew of the U-21; deficiencies of the see and avoid concept as a primary means of collision avoidance; and the lack of automated redundancy in the air traffic control system to provide conflict detection between participating and nonparticipating aircraft.
Final Report:
