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 with fuel endurance of 6 hours. The SP was the Pilot Flying (PF) on the left seat and the FI was the Pilot Monitoring (PM) on the right seat.
The ATPL training was initially scheduled to be conducted in Mallam Aminu International Airport Kano with Diamond 42 (5N-CZA and 5N-BZE) due to the availability of Jet A1 fuel. In the course of the training, DA-42 became unserviceable due to the Service Bulletin (SB) with reference number MSB 42-143/1 and MSB 42NG-086/1 requiring inspection of hole position and condition in the rudder steering bracket. NCAT decided to continue the training in Kaduna International Airport with Beech Baron 58 that uses AVGAS which is readily available in Kaduna.
