NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE PILOT STATED THAT HE STARTED THE TRIP, FROM NEW MEXICO TO NORTH DAKOTA, THE EVENING PRIOR TO THE ACCIDENT. BECAUSE OF POOR WEATHER, THE PILOT RE-ROUTED THE FLIGHT THROUGH SEVERAL ALTERNATE FUEL AND OIL STOPS. THE FLIGHT WAS EN ROUTE TO A PLANNED FUEL STOP WHEN THE ENGINE LOST OIL PRESSURE. THE AIRCRAFT WAS TOO FAR FROM A SUITABLE AIRPORT AND THE PILOT WAS FORCED TO LAND ON A HIGHWAY. THE PILOT SECURED A RIDE TO THE NEAREST TOWN AND PURCHASED OIL. AFTER ADDING OIL TO THE AIRCRAFT'S ENGINE HE ATTEMPTED A TAKEOFF FROM THE HIGHWAY--AFTER GOING WITHOUT SLEEP FOR ALMOST 30 HOURS. DURING THE TAKEOFF ROLL, THE AIRPLANE STRUCK A SPEED LIMIT SIGN ON THE EDGE OF THE HIGHWAY WITH ITS RIGHT WING. THE PILOT THEN LOST DIRECTIONAL CONTROL AND THE AIRCRAFT SWERVED INTO A DITCH.
