Beechcraft U-21 Ute

The crew was completing a local training mission at Yakima-Vagabond AAF. On final approach, the crew shut down the left engine to simulate a failure when the aircraft rolled to the left, lost height and crashed about 500 yards short of runway threshold. Both pilots were injured.

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.

On approach to Athens-Ellinikon Airport, the crew encountered unknown technical problems and was forced to ditch the aircraft some 21 km off the Greek coast. All three occupants were quickly rescued while the aircraft broke in two and sank.

On final approach to Davison AAF, the crew encountered foggy conditions and failed to realize his altitude was insufficient when the aircraft struck trees and crashed in a wooded area. All four occupants were killed.
