The student pilot reported that, after maneuvering the experimental amateur-built Rans S-12 airplane in flight for several minutes, he banked the airplane right, applied engine power, and increased the airplane’s pitch attitude but that “something didn’t feel right.” The student pilot responded by applying more power; however, the airplane started to descend. He turned the airplane’s nose into the wind, applied full power to the engine, and continued to increase the pitch attitude, but the airplane still would not climb. The student pilot then reduced the engine power to idle while continuing to bank right, and the airplane subsequently impacted the water. An examination of the airplane revealed no preimpact mechanical malfunctions or anomalies that would have precluded normal operation. According to federal guidance, the Rans S-12 falls under the low-inertia and/or high-drag category, which makes the airplane susceptible to unintentional stalls. When the student pilot banked the airplane right and applied engine power, the airplane likely entered a stall due to the airplane’s low-inertia and/or high-drag tendencies.
Probable Cause: The student pilot’s inadequate control of the airplane, which resulted in an aerodynamic stall and subsequent impact with water.
