Boeing 737-8200 MAX Fuel Leak, London Stansted, 24 April 2025

The AAIB published an investigation bulletin documenting a fuel leak on a Boeing 737-8200 MAX aircraft on 24 April 2025. The investigation found that pilots did not fully action the non-normal checklist and elected not to shut down the affected engine before diverting to London Stansted Airport. The AAIB highlighted that using thrust reverse on landing with an active fuel leak increased the risk of fire.

Airlines operating Boeing 737 MAX aircraft should review this bulletin and consider whether crew training on fuel leak procedures and non-normal checklist compliance warrants reinforcement. Aircraft manufacturers may also consider reviewing design or procedural guidance related to fuel system anomaly management during landing.
