Wichita - Wichita

The crew was performing a lateral and directional stability test. Changes from earlier tests combined new leading edge fairing, new flap setting, lower reference airspeed, and trial settings for the stall protection system (shaker and pusher). Engineers had briefed the crew data would be sufficient if the steady heading sideslip (shss) maneuver ended at a 15° sideslip, or at onset of stall warning; crew agreed to end at stall warning. During the test the capt continued past stall warning to 21° sideslip at full rudder. The airplane rolled rapidly through 360 deg° and entered a deep stall. The copilot attempted to deploy the anti-spin chute. However, all the chute system cockpit switches were not properly preset; instead of assisting recovery, the chute parted from the airplane. Full control was not regained before impact. The chute system design allowed deployment of the chute even when the hyd lock switch was in the unlocked position and the hooks clasping the chute shackle to the airframe were open. System tested ok before flight. All three crew members 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. Patterson.
