What happened
On 28 October 2025, at approximately 19:34 local time, a loss of separation occurred at Las Palmas de Gran Canaria Airport (GCLP) in Spain. An Airbus A3DO-251N, registered as HB-AYE and operated by EasyJet Switzerland SA, was on its final approach to runway 03L. Simultaneously, a formation of four military F-16 aircraft, designated as PROTE75, was authorized to depart from the parallel runway, 03R. While the commercial airliner was already established on its approach, three of the four military jets successfully departed. However, during the takeoff roll of the fourth F-16, the required separation between the two groups of aircraft was lost.
The investigation
The Swiss Transportation Safety Investigation Board (STSB) notified the occurrence of this serious airprox incident. The investigation into the circumstances surrounding the loss of separation involves the Spanish aviation accident investigation commission, CIAIAC. The inquiry focuses on the coordination between the arrival of the Airbus A320-251N and the departure of the military formation during the simultaneous use of parallel runways.
