Federal investigators say a plane was in the air for just 19 seconds before crashing and killing the pilot.
The National Transportation Safety Board issued its initial report on the crash.
49-year-old Martin Grab died November 20th after his plane went down after take-off from the Greater Binghamton Airport.
Investigators say because of the weather, Grab planned to fly primarily by using instruments and gauges in the cockpit.
He took off around dusk in fog, when visibility was about a quarter of a mile.
Investigators say the wreckage showed no signs of malfunctions, fire or failures before the plane went down.
Grab's plane first impacted a tree off Knapp Road in the Town of Maine.
Results of the NTSB's full investigation may not be released for one year.
