On February 19, 2026, about 0930 eastern standard time, a Tecnam P2006T, N964GV, was substantially damaged when it was involved in an accident near Miami, Florida. The flight instructor and student pilot were not injured. The flight was conducted under Title 14 Code of Federal Regulations Part 91 as an instructional flight. According to statements from the flight instructor and student pilot, a preflight inspection was completed prior to departure. Engine start, taxi, run-up, and flight control checks were completed with no abnormalities observed. The flight departed Miami Executive Airport (TMB), Miami, Florida and proceeded southwest to conduct multi-engine training maneuvers, including simulated engine failures and a single-engine minimum controllable airspeed demonstration. After completing the maneuvers, the flight was returning to TMB for an instrument approach. While in level flight at 2,000 feet msl and 6 nautical miles southwest of the airport, the student pilot observed a sudden, uncommanded left roll. Corrective inputs were applied, but maintaining control was difficult. The flight instructor assumed control. Lateral control remained restricted, both engines operated normally, and the autopilot was disengaged. The flight instructor then observed a piece of metal hanging from the left wing and suspected damage to the left aileron. An emergency was declared with air traffic control. Directional control was maintained using rudder and differential engine thrust, and the flight returned to TMB. The airplane landed safely without further incident. A post-flight examination confirmed substantial damage to the left wing, including the aileron assembly. The airplane was retained for further examination.
