What happened
The incident occurred during a flight from Hendon to Hanworth. While cruising at an altitude of 1,500 feet, the aircraft experienced a structural failure involving the wing. This mechanical failure caused the airplane to enter an uncontrolled descent. The craft ultimately crashed into a field located in Waltham. Both individuals on board were killed in the event.
Findings
The primary factor leading to the accident was the sudden loss of structural integrity in the aircraft's wing assembly during level flight. This failure rendered the airplane uncontrollable, leading directly to the fatal impact with the ground.
