Accident

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

Pilot Report

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

Witness Observation
