On 11 October around 14:10 (UTC +2), a Belgian Air Force F16 caught fire during maintenance works at Florennes Air Base. The fire completely destroyed that aircraft. The Belgian Air Force said a second F-16 received collateral damage.

On 12 October, Aviation24.be received more information on the incident: a technician was working on an F-16 when he accidentally activated the six-barrels 20mm Vulcan M61A-1 cannon of that F-16. The cannon was loaded and some bullets hit another F-16AM (FA-128). That aircraft had just been refuelled and was – together with another F-16 – being prepared for a (training) mission. Due to the bullets, the F-16AM exploded and damaged the other F-16.

Two technicians were injured after the blast, the Belgian Aviation Safety Directorate opened an investigation into the accident. The Belgian Air Force had 60 active F-16 aircraft remaining, including 48 on duty for NATO.
