NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

WHILE INITIATING A CROSS COUNTRY FLIGHT, THE EIGHT PLACE AIRCRAFT WITH NINE PERSONS ABOARD, IMPACTED TERRAIN SHORTLY AFTER TAKEOFF. ICE HAD BEEN SEEN ON THE WINGS AND HORIZONTAL STABILIZER, AND ICING CONDITIONS WERE PRESENT. THE AIRCRAFT WAS OVER MAXIMUM GROSS WEIGHT BY A MINIMUM OF 258 POUNDS, AND THE PILOT HELD AN EXPIRED STUDENT PILOT CERTIFICATE DATED AUGUST 17, 1984. A COPY OF A PRIVATE PILOT CERTIFICATE DESIGNATING MULTIENGINE LAND AND INSTRUMENT WAS FOUND IN THE PILOT'S PERSONAL BELONGINGS. FAA OFFICIALS CONCLUDED THAT IT WAS NOT A VALID CERTIFICATE. AN APPLICATION FOR A MEDICAL CERTIFICATE DATED MAY 30, 1991, INDICATED THE PILOT HAD 4,000 HOURS OF FLIGHT TIME. THIS FIGURE COULD NOT BE VERIFIED. JUST PRIOR TO TAKEOFF THE PILOT WAS OBSERVED BRUSHING SNOW OFF THE WINGS. FOLLOWING THE ACCIDENT GRANULAR ICE WAS FOUND ON THE AERODYNAMIC SURFACES.

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

AIRFRAME ICE AND THE PILOT'S FAILURE TO REMOVE IT. FACTORS WERE: AIRCRAFT WEIGHT EXCEEDED AND LACK OF PILOT CERTIFICATION.
