 Inquiry.

The inquest resumed on 13 August and heard more reports from witnesses and technical evidence from the investigation. The head of the Air Ministry investigation said the removal of parts of the wreckage for souvenirs had not helped his work. The investigation had shown no evidence of faulty material or bad workmanship but it was clear that the port wing had folded or collapsed upwards where it joined the fuselage. The engine and tail plane had broken away and the passengers were thrown out of the aircraft. The coroner directed that as a government inquiry would be held then some of the technical details of the accident need not be heard. The coroner could see no reason to further delay the verdict until after the inquiry by the Aeronautical Research Committee

. The jury returned a verdict "that the victims met their death falling from an aeroplane, the cause of the accident being unknown".

Investigation

The Junkers was an all-metal aircraft and had only flown about 100 hours since new and the flight was the third that day, Henderson had earlier flown his wife from Le Touquet to Croydon and had returned for four more passengers before going back again for the remaining four. Early indication showed that the port wing had become detached from the fuselage. The wreckage was removed to Croydon for investigation and four representatives from Junkers

Following the initial accident investigation an inquiry by the Accidents Investigation sub-committee of the Aeronautical Research Committee was opened on 3 September 1930. The inquiry was held at Croydon Airport in private and the members inspected the wreckage. The periodical Flight, in its issue dated 5 September 1930 called for the results of the investigation to be made public. It further called for all investigations into aircraft accidents to be made public. It also reported that representatives of some of the victims desired to ask questions at the enquiry. This was refused by Major Cooper, the Air Ministry

inspector in charge of the investigation. Major Cooper stated that solicitors for the victims would each receive a copy of the report when it was published.

The final report was issued in January 1931 and the committee concluded the cause to be the "failure of the tailplane under severe buffeting from air eddies produced by the centre section of certain low-wing monoplanes when the aircraft approaches the stalling attitude".

They reported that the aircraft flying in cloud may have been thrown into an unusual attitude which resulted in buffeting of the tailplane causing the port tailplane to fail and the aircraft entered a dive. The flutter effect on the starboard tailplane caused it to fail next the aircraft moving at high speed and reached a stalling attitude causing the port wing to break away. The rapid angular acceleration caused the engine supports to break and the engine to fall away. Nine other causes were investigated but dismissed by the committee.
