RAF Spitfire Pilot's Death Likely Caused by Decades-Old Engine Debris, Report Finds
A report into the crash that killed Squadron Leader Mark Long suggests a blockage in the carburetor reduced engine power.
The death of an RAF Spitfire pilot during a Battle of Britain Memorial Flight was "very likely" caused by a "decades-old piece of debris" in the aircraft's engine, a report has concluded. Squadron leader Mark Long, 43, died on May 25, 2024, when his plane crashed shortly after taking off near RAF Coningsby in Lincolnshire.
The Defence Safety Authority's report stated that engine performance data and witness statements aligned with what would be expected if the aircraft was experiencing fuel starvation. The service inquiry panel concluded that debris within the carburetor "partially blocked the lean metering jet," which reduced fuel flow, decreased engine power, and ultimately prevented the aircraft from maintaining safe flight.
Chemical analysis revealed the debris had been present for decades. The report also identified issues with the pilot's restraint system, noting that this design was "critical in the survivability of the pilot" and was "very likely to have been an aggravating factor in the accident." Modifications to enhance survivability were recommended.
Squadron Leader Long, who was on his fourth season with the Battle of Britain Memorial Flight, was born in Bury St Edmunds and graduated initial officer training in 2003. His career included flying the Tucano, Hawk, and Harrier GR7/9, and he was the last RAF Harrier pilot qualified for operations off an aircraft carrier. He later joined the Typhoon Force at RAF Coningsby in 2012, serving as a Typhoon display pilot and instructor, and also undertaking quick reaction alert duties defending UK sovereign airspace. His family described him as someone who "lived his life with an unwavering passion with laughter, love and dedication to his family."
