Narrative Report
On August 28, 1985 at 01:45 AM, Hickory - Charlotte experienced a crash involving Beechcraft 99 Airliner, operated by Sunbird Airlines, with the event recorded near Conover North Carolina.

3 people were known to be on board, 3 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 3, crew fatalities: 3, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. Aircraft was on training flight for initial copilot qualification for commuter air carrier. Instructor and two trainees were on board. The aircraft departed Charlotte at about 2314 edt for the Hickory area for training. At about 0015 edt, it was reported that the crew visited the Hickory FSS. After departing Hickory, the aircraft climbed to 5,500 feet and remained generally between Charlotte. At about 0145 edt, radar data showed the aircraft to be in a steep descent and gaining speed. The aircraft collided with tree limbs, a utility pole and the ground in about 35° angle of descent in a residential area of Conover, NC. Investigation revealed a nose up trim, which was approximately 75% of the available up-trim (3.38° upnose). This is an abnormal setting; so the entire trim unit was retained and sent to the Talley Corp for detailed exam. The ram end fittings were sent to ga tech research for surface fracture analysis. The exam showed ductile overstress and no indication of pre-cracked condition. Pitch trim emergencies are a part of sunbirds c-99 training program (fit 1 & 2). All three occupants were killed.

Lt. Frank Stuart Patterson, son and nephew of the co-founders of National Cash Register, is killed in the crash of his DH.4M, AS-32098, at Wilbur Wright Field during a flight test of a new mechanism for synchronizing machine gun and propeller, when a tie rod breaks during a dive from 15,000 feet (4,600 m), causing the wings to separate from the aircraft. Wishing to recognize the contributions of the Patterson family (owners of NCR) the area of Wright Field east of Huffman Dam (including Wilbur Wright Field, Fairfield Air Depot, and the Huffman Prairie) is renamed Patterson Field on 6 July 1931, in honor of Lt.
