Confidence Rating: Accident investigation report completed and information captured
The Flight Instructor (CFI) piloting the airplane reported he was not performing aerobatic maneuvers; however, a review of the onboard airplane video by the Federal Aviation Administration (FAA) Air Safety Inspector revealed that the pilot had been performing aerobatic maneuvers in an airplane not certified for aerobatic flight.

During the flight, the airplane entered a spin, descended uncontrolled, and impacted a creek bank. The airplane sustained substantial damage to the engine compartment, wings, fuselage, and tail section. The pilot stated there were no mechanical malfunctions or failures prior to flight, which would have prevented normal airplane operations.

According to Aero Sp. Z.O.O AT-4 LSA Pilot Operating Handbook, aerobatics and intentional spins are prohibited.
Probable Cause: The pilot's decision to perform aerobatic maneuvers in an airplane not certified for aerobatic flight, which resulted in a loss of control and collision with terrain.
