Atlanta - Greenville

Air South Flight 168 departed Atlanta at 21:07. At 21:13 the flight reported level at its assigned cruising altitude of 7,000 feet. The Beech had been cruising for eleven minutes when it attained a gradual nose down attitude due to a change in the longitudinal trim. The pilots noticed the change after about six seconds and initiated a recovery action. The horizontal stabilizer continued to move to a full nose down position. Excessive pulling force on the control column was necessary to recover from the high speed dive. The necessary stick forces for such an out-of-trim condition can exceed the capability of one pilot, and in some cases two pilots, to control. The Beech continued to descend until both wings failed at high speed, just before the airplane crashed into the ground in a near vertical attitude.

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. Patterson.
