## Probable cause

The improper maintenance of the left engine by company maintenance personnel (failure to flush metal from the oil system and failure to properly preserve the engine for storage) resulting in a total failure of the master rod bearing and contamination of the engine oil system with metal, which prevented the left propeller from feathering. This resulted in the airplane being unable to  maintain altitude following loss of engine power and subsequent ditching in a lake. A factor in this accident is the aircraft operator and flight crew exceeding the maximum allowable takeoff weight for the airplane.
