What happened
The incident occurred while the aircraft was conducting a training flight in the vicinity of Poole. During the approach for landing within the Poole harbor, the seaplane lost control. The loss of control led to a crash into the water, after which the airframe was destroyed by fire and subsequently sank.
The accident resulted in significant casualties among the personnel on board. Three crew members were killed in the event, while three others sustained injuries. The individuals who perished included two radio operators and one flight engineer. The specific names of the deceased are recorded in historical archives associated with the location, but this account refers to them by their roles to maintain neutrality.
Findings
The source material indicates that the primary sequence of events involved a loss of control during the landing phase. No further technical investigation details or contributing mechanical factors are provided in the available record beyond the immediate loss of control and the subsequent fire.
