What happened
During the climb-out phase, the aircraft encountered a crosswind at an altitude of approximately 30 feet above the runway. The runway is located on a plateau, and a windsock is positioned at the departure end of the runway on a 30-foot steel pole.
Due to these unfavorable wind conditions, the pilot was unable to maintain alignment with the runway, and the aircraft failed to gain altitude. The Certified Flight Instructor (CFI) took control of the yoke in an attempt to maintain both airspeed and altitude while navigating to avoid a nearby vineyard.
The crew noted that there was a lack of suitable terrain or airport environment available for a forced landing, and the aircraft remained unable to climb. In an effort to avoid striking the windsock on the 30-foot pole, the CFI increased the pitch of the aircraft. This maneuver resulted in an aerodynamic stall, causing the aircraft to impact a grassy area located approximately 100 feet from the runway edge and roughly 20 feet below the airport elevation. The occupants were not injured.
