The incident occurred on the taxiway as the aircraft was preparing to take off for Frankfurt, Germany. The flight, identified as 4Y307, was initially scheduled to depart at 16:55 but the security alert caused a significant delay, with the operation finally commencing at 19:30.
The airport protocol, coordinated by Aena and state security forces, mandates the immediate evacuation of passengers and thorough inspection of luggage using scanners and explosive detection dogs in response to such alerts.
Pilots aborted the takeoff maneuver upon receiving instructions from air traffic control and returned to the assigned terminal parking. Passengers disembarked with their hand luggage while security teams conducted the inspection. After confirming it was a false alarm, travelers re-boarded the aircraft.
