On May 4, 2017, about 1400 central daylight time, an Air Tractor AT-502B, N144HF, was destroyed by a post-crash fire following a partial loss of engine power after takeoff from the Bar-T Airport (2F4), near Tahoka, Texas. The commercial pilot sustained minor injuries. The aircraft registered to Wilmington Trust Company, Wilmington, Delaware, and operated by Plains Aerial Applications, Olton, Texas, under the provisions of Title 14 Code of Federal Regulations Part 137 as an aerial application flight. Visual meteorological conditions prevailed in the vicinity and no flight plan was filed. The flight originated from 2F4, Tahoka, Texas, and its intended destination was to a local field to apply chemicals.

The pilot reported that he had flown several aerial application flights in the morning and the airplane was operating normally. Prior to the final flight of the day, while the airplane was being loaded with chemicals, he heard a noise, but all engine gauges appeared to indicate that everything was normal. He taxied down runway 35, applied power, and took off. The engine gauges indicated turbine inlet temperature of 8,000° and propeller RPM 2,200. About 30 feet above the ground, the airplane plane started making a noise and the engine was surging. The pilot attempted to add more power, but the engine was not responding, and he tried to keep the airplane flying. Just as the pilot was going to dump the chemical load, the airplane veered to the left and hit the ground. After the pilot exited the airplane, a post-crash fire ensued.

A witness at the airport saw the airplane takeoff and fly about 1/2 way down the runway. He stated that the airplane touched down on its left wheel and became airborne again. He saw the airplane past the departure end of the runway and it was losing altitude. He then saw the left wing tilting down and the airplane impacted the ground.

Detailed examination of the engine was not possible due to the severe fire damage. No additional information on the accident was available.
