NTSB Narrative Summary Released at Completion of Accident
Two airplanes, a high-wing Cessna, and a low-wing Beech, collided in midair, about two miles north of a non-tower controlled general aviation airport. Both airplanes had departed the same airport about 8 minutes apart. Radar data from a nearby air traffic control approach facility disclosed that the first to depart was the Beech, and the pilot requested VFR flight following from air traffic control. Due to workload, the air traffic control specialist declined to provide the service. Radar derived information indicated that the Beech was maneuvering north of the airport at altitudes between 2,600 and 2,900 feet msl, and then began a descent and a return to the airport. The Cessna began his departure and climb as the Beech approached the airport. A witness related that he saw both airplanes approaching each other, about ½ mile apart, on an apparent collision course, but not directly head-on. He watched as both airplanes closed their relative distance, and saw both airplanes roll towards each other, clipping each other's wing. Both airplanes immediately descended to impact. Postaccident inspection disclosed no preaccident mechanical issues with either airplane. The sky was clear, and both pilot's had been communicating on the local airport Unicom (voluntary traffic advisory) frequency. Federal aviation regulations state that each pilot has the responsibility to see and avoid each other.
NTSB Probable Cause Narrative
The inadequate visual lookout of the pilots in both airplanes, and their failure to maintain clearance from each other's airplane.
