The flight operated in visual meteorological conditions. According to the pilot's statement, after departing Timmerman he realized that the tachometer for the left propeller was not operating. He found that he was able to keep the left and right propellers in synchronization at either full or cruise power, so he decided to continue the flight.

While on final approach, he became preoccupied with the problem and impacted trees.
