NTSB summary
HISTORY OF FLIGHTOn July 18, 2016, about 1105 mountain daylight time, a Diamond DA40, N419FP, impacted terrain while maneuvering near Logan, Utah. The private pilot was fatally injured, and the airplane was destroyed. The airplane was registered to and operated by Utah State University as a 14 Code of Federal Regulations Part 91 personal flight. Visual meteorological conditions prevailed for the flight, and no flight plan was filed. The local flight originated from Logan-Cache Airport (LGU), Logan, Utah, about 1034. According to the pilot's flight instructor, the purpose of the flight was for the pilot to practice maneuvers required to obtain a commercial pilot certificate. These maneuvers included lazy 8's, 8's on pylon, steep turns, chandelles, steep spirals, and stalls. A witness located about 1/3 mile from the accident site observed the airplane flying in slow counterclockwise circles while descending with the engine power at idle. He assumed the pilot was practicing stalls. He reported "unusual" weather that day; the wind was gusting 30-40 mph; however, in between the gusts, it was "dead calm." As the airplane continued to execute counterclockwise turns, the witness noticed it "rocking quite a bit as it descended through the gusts until it disappeared" from his sight. A review of radar data showed that the airplane departed from runway 35 at LGU, turned south, and proceeded toward the practice area. At 1043:36, the airplane started maneuvering in the practice area at 7,300 ft mean sea level (msl). During the next 5 minutes, the airplane's altitude varied between 7,300
Probable cause
The pilot's exceedance of the airplane's critical angle of attack while maneuvering in turbulence and gusty wind conditions, which resulted in an aerodynamic stall/spin.
