NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The airline transport certificated pilot was departing eastbound, and up-river in a float-equipped airplane. He said the airplane was on-step, and he attempted to lift one float out of the water during the takeoff run, but was unsuccessful. He then decided to abort the takeoff by closing the engine throttle, and the airplane collided with the river bank. The left float assembly was torn off the fuselage, and the airplane received structural damage to the fuselage.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's delay in aborting the takeoff run when he was unable to lift one float off the water, which resulted in a subsequent collision with terrain. A factor contributing to the accident was a river bank.
