NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

After takeoff, the pilot raised the landing gear and flaps and manually manipulated the turbocharger. As he was adjusting the turbocharger, the engine power reduced to idle, surged to full power, and then reduced back to idle. To avoid obstacles at the end of the runway, the pilot pushed the flight controls forward and landed the airplane on the remaining runway. During the hard landing, the amphibious landing gear collapsed, which resulted in substantial damage to the airplane. A postaccident examination of the engine and related systems revealed no mechanical malfunctions or failures that would have precluded normal operation. Fuel was found on board the airplane, and no evidence of fuel contamination was found. The reason for the partial loss of engine power could not be determined.

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

The partial loss of engine power during takeoff for reasons that could not be determined because postaccident examination revealed no mechanical malfunctions or failures that would have precluded normal operation.
