SHK concluded that the incident took place because the Gripen pilot inadvertently went below his assigned flight level and ended up on the same flight level at the passenger aircraft. SHK placed the root cause of this with the lack of adequate routines in the Swedish Air Force for receiving and reading back instructions from air traffic control. A contributary cause of the incident was said to be a lack of support systems in the Gripen to help the pilot with the aforementioned task. Such a system is currently being introduced in the Swedish Air Force Gripens. The system will alert the pilot if the flight deviates from the assigned flight level.
