## Probable cause

The pilot’s exceedance of the airplane's critical angle of attack during an improper go-around procedure which resulted in an aerodynamic stall.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Analysis

During landing, the airplane bounced, and the pilot applied power to go around. The pilot reported that the engine did not produce full power and the airplane began to slow down. Onboard data indicated that the pilot accelerated the airplane to a maximum speed of 70 kts before he retracted the flaps; the airplane rolled right and impacted the runway, resulting in substantial damage. Examination of the airplane revealed no evidence of mechanical malfunctions or failures that would preclude normal operation. The airplane's published stall speed in the landing configuration was 60 knots; and 69 kts with landing gear and flaps retracted. The procedure for a go-around included retracting the wing flaps incrementally after attaining an airspeed of 80 kts. The circumstances of the accident are consistent with the pilot's failure to attain the proper airspeed during the go-around, and his improper decision to fully retract the wing flaps before attaining adequate airspeed, which resulted in an exceedance of the airplane's critical angle of attack, an aerodynamic stall, and impact with the runway.

## Factual narrative

On July 3, 2018, about 1257 central daylight time, a Piper PA-46-350P airplane, N689KC, was substantially damaged when it was involved in an accident near Springhill, Louisiana. The pilot and passengers were not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that, during landing, the airplane bounced on the runway, and he applied engine power to go around; however, the engine would not produce full power and the airplane began to slow down. The pilot retracted the landing gear and flaps, and the airplane subsequently impacted the runway. A witness to the accident observed the airplane as it conducted a landing to the Springhill Airport. The witness estimated that the airplane touched down about 1/3 of the way down the 4,202-ft-long runway. When the airplane touched down, it bounced, then bounced a second time in a nose-high attitude. The right wing dropped, and the airplane impacted terrain. The responding Federal Aviation Administration (FAA) inspector reported the fuselage was substantially damaged during the accident. He also reported that a visual examination of the airplane did not detect any preimpact anomalies with the airplane. Data retrieved from the airplane’s G1000 system captured the accident flight. The airplane descended at 12:39. As it descended below 1,000 ft, the engine rpm was 2,400 rpm. At 12:56:40, the engine speed decreased, and reached 1,225 rpm at 12:56:57. While the engine speed decreased, the airplane pitched up. The airplane crossed the runway threshold at 12:56:47 with the airspeed about 80 knots (kts). At 12:56:57, the engine speed increased to over 2,400 rpm in two seconds and remained there throughout the accident sequence. At this point, pitch had increased to 11° nose up and the airspeed was 59 kts. Airspeed increased about 3 seconds after the engine was increased. At 12:57:13, the pitch was 17° nose up and the airspeed was 70 kts. The data also indicated that the airplane was about 220 ft in altitude before it started a roll to the right. The data indicated that the airplane collided with the ground at 12:57:19. According to the airplane's Pilot Operating Handbook, the airplane's minimum landing approach and go-around speed was 80 kts. The published stall speed in the landing configuration was 60 kts; with landing gear and flaps retracted, the stall speed was 69 kts. The go-around procedure stated that after applying full rich mixture, propeller rpm, and throttle and attaining 80 kts, the landing gear should be retracted, and the flaps retracted incrementally. Of note, this accident was initially reported as N479CD due to the registration markings on the airplane, during the investigation it was discovered that the registration was changed to N689KC about a year prior to the accident.
