Incident Overview
A pilot, accompanied by one passenger, was conducting practice maneuvers in an airplane. The planned exercises included lazy eights, circles around a point, S-turns, and low flight.
The Maneuver and Loss of Control
While performing slow flight at full power with flaps deployed, the aircraft's right wing dropped. The pilot attempted to correct by lowering the nose and applying aileron and rudder. However, the airplane entered a spin and began to oscillate left to right. The pilot was unable to fully recover control before the aircraft impacted the surface of a lake.
Post-Impact Egress
Following the impact, both the pilot and passenger were able to open the aircraft's door and exit the airplane. No further details about their condition or the extent of damage were provided in the source.
