The pilot increased engine power, but "the high rate of descent continued," and he then increased the engine power further. A slow left roll developed, and he applied full right aileron and full right rudder to arrest the left roll. He also reduced the engine power, and the left roll stopped. The pilot regained control of the airplane, but the airplane's heading was 45° left of the runway heading, and the airplane impacted trees and then terrain. The airplane caught fire, and the pilot and passenger exited through the emergency exit. The airplane sustained substantial damage to the windscreens and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during approach, about 500ft above the ground and 81 knots he, "felt the descent rate increase significantly." The pilot increased engine power, but "the high rate of descent continued" and he increased the engine power further. A slow left roll developed, and he applied full right aileron and full right rudder to arrest the left roll. Additionally, he reduced the engine power and the left roll stopped. The pilot regained control of the airplane, but the airplane's heading was 45° left of the runway heading and the airplane collided with mesquite trees and subsequently the terrain. The airplane caught fire and the pilot and passenger exited through the emergency exit. The airplane sustained substantial damage to windscreens and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N850NK](https://openairdocs.org/deregistered/N850NK-2020-01-14), registration cancelled 2020-01-14, S/N 432, built 2007 (OpenAirDocs) - Reported make and model: SOCATA TBM700 - Registry model: [Socata TBM 700](https://openairdocs.org/model/socata-tbm-700) (registry code 8682000) (OpenAirDocs) - Registry engine: [Pratt & Whitney PT6A66D](https://openairdocs.org/engine/pratt-whitney-pt6a66d) (registry code 52281, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: 432 - Year built: 2007 - Airframe hours: 2878 - Engines: Pratt&Whitney PT6A66D 850 horsepower turbo prop - Damage: Substantial damage - Fire: On-Ground - Flight: Personal, Part 91 - Operator: Mt Margarett LLC - Registered owner: Mt Margarett LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 25, 2019 - Departed: SJT, San Angelo, TX - Destination: BKD, Breckenridge, TX - Flight plan: IFR - Airport: BKD, Stephens County, runway 17, 4,997 × 100 ft, asphalt - Equipment: Electronic multifunction display, Electronic flight bag or handheld device, Electronic primary flight display, Onboard weather, Stall warning system, ADS-B, Auto-pilot ## Flight crew As NTSB recorded them.
