An enquiry into the crash was hastily set up. The commission's report concluded that the crash was caused by damage to the differential gear, which caused an oil leak. Then a number of teeth broke off the spur wheel and ignited the oil. Sabotage or human error was ruled out. The aircraft, W. Nr. 14256, was ferried to the unit via Bari, Italy. The mission that ended in its destruction was its first mission. Schland and Pöttgen's statements led Neuman concluded there was no fire and a glycol leak was responsible for the engine failure. He ruled out the existence of a fire, for he did not believe Marseille could have spoken for nine minutes without fatigue in smoke caused by a fire.
