Air Union — Flight F-AEBY

An Air Union Farman F.60 Goliath suffered a catastrophic structural failure while en route from Paris to London, resulting in the deaths of all six people on board. While cruising at approximately 3,000 feet, the aircraft's wing detached in mid-air, causing the airframe to plummet into a field near Monsures. A witness on the ground reported hearing an explosion before the aircraft fell. The wreckage was consumed by a post-crash fire, and investigators later located the detached wing and a pair of wheels several hundred yards away from the main impact site.

Report

Investigation Summary

The flight departed Le Bourget at 12:35 local time, carrying two crew members and four passengers, including Émile Pierrot, the Technical Director of Air Union. Approximately one hour into the flight, while flying over the Somme region, the aircraft experienced a sudden structural breakup. A local garde champêtre (rural guard) witnessed the event, describing an aerial explosion followed by the aircraft's descent. The investigation confirmed that the breakup was not an engine explosion but a structural failure of the wing. The separation of the wing and parts of the undercarriage in flight rendered the aircraft completely uncontrollable. The Farman Goliath was a prominent early airliner, but this accident highlighted the vulnerabilities of early wooden and fabric wing structures under the stresses of scheduled commercial service.

Final Conclusions

The accident was caused by the structural failure of a wing during flight. Evidence for this was conclusive, as one of the wings was discovered 200 yards (180m) from the main wreckage, and a pair of undercarriage wheels was found near the Amiens to Beauvais railway line, also several hundred yards from the crash site.
