Analysis

The private pilot stated that, during the initial climb after takeoff, he checked the airspeed and lowered the airplane's nose. He reported that the airplane rolled to the right, which he corrected, then the airplane "abruptly" rolled to the left. He was unable to correct the roll, and the airplane descended and impacted terrain. The pilot reported that there were no mechanical failures or malfunctions of the airplane. A witness reported that the airplane was airborne in a wings level, "very high" nose-up attitude when he first saw it. He stated that, after a few seconds, the left wing and the nose dropped. Shortly after that, the right wing dropped, the nose-down attitude increased, and the airplane impacted terrain. A video of the accident corroborated the witness account. The witness's recollection of the accident, along with the video of the accident airplane just before the accident, suggest that the pilot exceeded the airplane's critical angle of attack during the initial climb, which resulted in an aerodynamic stall. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain adequate airspeed during takeoff, which resulted in an exceedance of the airplane's critical angle of attack and subsequent aerodynamic stall.

Findings

Personnel issues
Aircraft control - Pilot (Cause)




NTSB Identification: CEN17LA001
14 CFR Part 91: General Aviation
Accident occurred Saturday, October 01, 2016 in Jennings, LA
Aircraft: DRAKE KITFOX SPEEDSTER, registration: N157D
Injuries: 1 Serious.

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On October 1, 2016, at 1300 central daylight time, an experimental light sport, amateur-built Drake Kitfox Speedster, N157D, collided with the terrain following a loss of control after takeoff from the Jennings Airport (3R7), Jennings, Louisiana. The pilot received serious injuries. The airplane was substantially damaged. The airplane was registered to and operated by the private pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which was not operated on a flight plan. The intended destination was Slaughter Airpark (SL77), Slaughter, Louisiana.

The pilot reported that he was the last airplane in a flight of four to takeoff. He stated he verified his altitude and airspeed, and retracted the flaps during the takeoff. He stated he checked the airspeed, lowered the nose of the airplane, and resumed the climb. The pilot reported the airplane rolled to the right, which he corrected, then the airplane "abruptly" rolled to the left. He was unable to correct the roll and the airplane descended to impact with the terrain. The pilot reported that there were no mechanical failures/malfunctions of the airplane.

A witness reported the airplane was airborne in a wings level, "very high" nose up attitude when he first saw it. He stated that after a few seconds the left wing dropped and the nose lowered. Shortly after that, the right wing dropped and the airplane nosed down even more until it impacted the terrain.

A video posted on YouTube by furley85 showed the airplane climbing out in a steep, nose-high attitude after takeoff. The airplane was a couple hundred feet above the grass airstrip when the left wing dropped and the nose lowered. The airplane rolled back through wings level then the right wing dropped and the airplane impacted the terrain. The airplane received substantial damage to the wings and fuselage.
