On 31st December, 2022 at about 10:16 h, a Beech Baron 58 aircraft with nationality and registration marks 5N-CAG, operated by Nigerian College of Aviation Technology (NCAT), Zaria was schedule for Airline Transport Pilot Licence (ATPL) training on instrument approach procedures in Kaduna International airport. There were four persons onboard including the Flight Instructor (FI), the Student Pilot (SP) and two additional student pilots seated at the rear. The aircraft had six hours of fuel endurance. The SP was the Pilot Flying (PF) on the left seat and the FI was the Pilot Monitoring (PM) on the right seat. At 10:15 h, 5N-CAG requested for take-off which was granted. The flight crew further stated that after line-up for take-off the throttle was advanced, confirmed centre line and then full power, wind was 23 kt. Immediately after lift-off, the cockpit door on the right side opened. The SP continued with the take-off while the FI attempted to close the door. As the FI tried to close the door, the SP reduced the throttle lever to 300 RPM. With the door still open, the crew decided to land the aircraft straight ahead on the remaining runway. The FI took over control of the aircraft, closed the throttle levers and confirmed from the SP if the landing gears were down. The SP replied landing gear down with three greens.
