Euroworld — Flight N3710G

A Douglas A-26 Invader warbird, nicknamed Double Trouble, crashed during the Battle of Britain airshow at Biggin Hill while performing an aerobatic maneuver. The aircraft was conducting a fast run along the crowd line at 150 feet before attempting a barrel roll or wingover. During the maneuver, the aircraft became inverted, the roll rate increased, and the bomber dived into a valley at the end of the runway. All seven occupants, including six passengers, were killed. At the time, regulations did not strictly prohibit carrying passengers during air displays, a fact that changed as a direct result of this accident.

Report

Investigation Summary

The aircraft involved was a vintage medium bomber, a Douglas A-26C-25-DT Invader built for the USAAF in 1943 with the serial number 43-22612. Later operated as a civilian warbird, it was performing for a large crowd at the Biggin Hill Battle of Britain airshow on the day of the accident. Despite the aircraft's size and the presence of six passengers, the pilot initiated a low-level aerobatic maneuver. Investigators noted that the aircraft likely entered the maneuver at an insufficient speed and altitude for a safe recovery. As the aircraft reached the inverted position, the roll rate increased unexpectedly, and the nose dropped into a steep dive. Recovery was impossible from the initial height of 150 feet. The crash was a watershed moment for UK aviation safety, leading the Civil Aviation Authority (CAA) to implement immediate and strict prohibitions on the carriage of passengers during aerobatic air display maneuvers to prevent unnecessary loss of life in high-risk flight profiles.

Final Conclusions

The accident was caused by the pilot's decision to perform a low-level aerobatic maneuver (a barrel roll or wingover) at an altitude insufficient for recovery, especially while carrying passengers. The loss of control while inverted led to a fatal impact in the valley adjacent to the runway.
