Aircraft involved
Probable cause & findings
The failure of the pilot to maintain airspeed during the initial climb after takeoff, which resulted in an aerodynamic stall.
Factual narrative
The pilot/part owner of the airplane decided to go fly with a pilot friend The preflight inspection and preflight ground run up check went unremarkable. The pilot elected to let the friend fly the airplane. The pilot flying stated that they departed with a short field technique climbing up to 150 feet above ground level (agl). He pushed forward on the flight control stick to lower the nose to a straight and level flight attitude. The airplane began to sink upon completion of the pushover maneuver. He pushed the control stick forward to gain airspeed; throttle at full engine power. The left wing dipped followed by the ring wing, which dropped off sharply. He applied full left rudder and full left aileron, the right wing started to recover; however, there was insufficient altitude and the airplane impacted the ground. Ground witnesses stated that they observe the airplane takeoff and climb in about a 45 degrees nose high attitude. As it gained altitude it struggled to gain airspeed. At its highest point of the climb, about 100 feet agl, the wings dipped to the right and then left; wobbling. The airplane began to nose down toward the right in a steep angle. The wings wobbled again. The nose of the airplane started to rise just before the right wing tip contacted the ground. The airplane then spun 180 degrees coming to a full stop on its right side. After an unremarkable preflight inspection and preflight engine run-up, the pilot, who was a friend of the pilot/part owner in the passenger seat, departed with a short-field technique and entered a steep climb. He then pushed forward on the flight control stick to lower the nose to a straight and level flight attitude; the airplane then began to sink. The pilot pushed the control stick forward to gain airspeed and ensured that the engine was at full power. The left wing dipped, followed by the right wing, which dropped sharply. The pilot applied full left rudder and full left aileron, and the right wing started to recover; however, there was insufficient altitude and the airplane impacted the ground. Witnesses stated that they observed the airplane take off and climb in about a 45-degree nose-high attitude. They further stated that, as the airplane gained altitude, it struggled to gain airspeed as it climbed to about 100 feet above ground level. The wings dipped and wobbled before the airplane struck the ground. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
