The pilot of a small plane that crashed in Southern California last month had difficulty starting one engine before takeoff, a preliminary report by investigators says.
Three people were killed initially in the Feb. 27 crash in Riverside, and one of two survivors died Tuesday.
The report Wednesday by National Transportation Safety Board investigators says the pilot started the right engine of the Cessna T310Q and made several unsuccessful attempts to start the left engine before it began running.
The plane departed for San Jose and began a left turn as it entered clouds. Video then showed the plane descending in a slight left-wing-low attitude about a mile from the airport.
The preliminary report cites a number of other facts about the flight but draws no conclusions about what caused the crash.
