What happened
The incident occurred while the seaplane was executing an approach to land on the Hoogly River in Calcutta. The flight was conducted under conditions of strong winds. Upon making contact with the water surface during the landing phase, the aircraft immediately went out of control. This loss of stability resulted in the seaplane sinking into the river.
Despite the total loss of the airframe, all eight individuals on board were successfully rescued from the water. No fatalities or injuries were reported among the occupants.
Findings
The official investigation attributed the accident to a loss of control upon landing. The primary contributing factor identified was the presence of strong winds during the critical phase of the approach and touchdown.
