Accident Sequence
On June 7, 2025, at approximately 1252 Pacific daylight time, a Yakovlev YAK-50, registration N150YK, was substantially damaged during a forced landing near Hayward, California. The pilot reported minor injuries. The flight was conducted as a Title 14 Code of Federal Regulations Part 91 personal flight.
The pilot stated that this was the first flight after the aircraft completed an annual inspection. He topped off the fuel tank with about 41 gallons of fuel and reported that all preflight and engine runup checks were within operating range. After receiving takeoff clearance, the pilot increased engine power and observed normal instrument indications. As the airplane ascended, he raised the landing gear and noted the propeller indicating 100% power. The airplane accelerated normally for about 5 to 6 seconds. At approximately 100 feet above ground level and 100 knots airspeed, the engine began to run rough. The pilot declared an emergency, and the tower controller cleared him to land on any runway. Despite no changes to throttle or propeller settings, engine power degraded to about 80%. The pilot elected to make a 180-degree turn to land on the opposite runway direction. While about 90 degrees through the turn, at roughly 30 feet above ground, he lowered the landing gear. At that moment, the engine lost all power. Unable to maintain altitude, the pilot leveled the wings and performed a forced landing on a grass field.
Damage Details
During the landing roll, one of the main landing gear separated, and the airplane struck terrain, resulting in substantial damage to both wings.
