British Airways flight BA519 from Lisbon to London Heathrow declared an emergency on July 5, 2025, while entering British airspace due to a technical issue with the aircraft’s nose gear steering system. The Airbus A319 (registration G-EUPG) departed Lisbon Airport at 18:33 WEST, nearly two hours behind its scheduled departure time, and was originally expected to land at Heathrow at 19:10 BST.
As the flight began its approach to London Heathrow, pilots activated the emergency squawk code 7700, signaling the need for a priority landing because the nose gear servo was malfunctioning, preventing the aircraft from steering on the ground. This technical issue raised concerns about safe taxiing after touchdown, prompting emergency protocols at the airport.
Air traffic control initially switched landings from runway 27L to 27R at 20:50 BST to manage traffic and emergency response. However, BA519 returned to final approach on runway 27L by 20:58 BST. The aircraft safely landed on runway 27L at 21:05 BST, where it was immediately met by emergency vehicles including fire trucks. The plane vacated the runway by 21:07 BST and was inspected on the taxiway, escorted by fire services.
By 21:24 BST, the aircraft had been guided to stand A14 at Terminal 5 for further inspection and passenger disembarkation. Normal landing operations resumed on runway 27L shortly before this. There have been no reports of injuries or further complications, and the incident was managed efficiently with coordinated emergency response.
The delay in departure from Lisbon and the subsequent emergency landing caused a ripple effect on airport operations, temporarily halting runway 27L landings and drawing attention on social media and flight tracking platforms. The incident underscores the importance of rigorous aircraft maintenance and emergency preparedness, as well as the professionalism of flight crews and ground teams in handling in-flight technical difficulties safely.
British Airways and Heathrow Airport have not released detailed statements yet but confirmed the safe landing and ongoing investigation into the nose gear servo malfunction. Passengers on board were reported safe, and the aircraft is undergoing technical assessment to determine the cause and necessary repairs. This event adds to a series of operational challenges faced by the airline in recent months, highlighting the critical role of safety protocols in commercial aviation.
