The TL-3000 Sirius was on a training flight with an instructor and a student on board. After three touch-and-gos on runway 07 of Hilversum airfield, the aircraft landed, intending to perform another touch-and-go. The aircraft had bounced on landing, after which the instructor took the controls and made a restart. The controls were then handed over to the student once again. At an altitude of approximately 300 feet, when the aircraft was in line with the runway and turned into the crosswind, the engine started to stutter. The instructor took back the controls once again and performed a failure check. He moved the throttle to idle and back to full power several times. The engine continued to stutter and delivered inadequate power to fly a short approach. The altitude was such that no other option remained but to land in the trees on a military terrain bordering the airfield. The aircraft came to a halt in a treetop. The two occupants were rescued from their situation by the fire department. They remained unharmed but the aircraft was heavily damaged.
A limited technical investigation was conducted of the engine, checking for the presence of fuel and oil, the control levers of the engine, the spark plugs, carburettor, cylinders, and valves, among other things. The investigation did not yield a technical explanation for the engine stutter.
