The W.10 plane named "City of Ottawa" crash-landed into the sea of the English Channel following loss of engine power.
Investigators found the No. 4 connecting rod assembly of the starboard engine completely broken as a result of a fracture of the big-end bearing studs. It appeared that the bearing studs on the port side of the bearing fractured in fatigue.
The airplane operated on a flight from London-Croydon to Zürich, Switzerland, via Paris, France and Basel, Switzerland.
The primary cause of the accident was the fracture under fatigue of studs in the front or No. 4 big end bearing of the starboard engine.
