## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AIRCRAFT WAS ENROUTE FROM BOULDER CITY MUNICIPAL AIRPORT, NV (BVU) TO AN ORIGINAL DESTINATION OF ONTARIO, OR (ONO). NO FLIGHT PLAN WAS FILED, BUT THE PILOT WAS IN CONTACT WITH ATC AND WAS RECEIVING BASIC RADAR TRAFFIC INFORMATION SERVICES WHILE ENROUTE, WITH THE AIRCRAFT?S ALTITUDE VARYING BETWEEN 11,000? AND 13,000? MSL.  PILOT RECEIVED SEVERAL REPORTS FROM ATC ABOUT TURBULENCE, ICING AND MODERATE TO HEAVY PRECIPITATION DIRECTLY AHEAD OF THE AIRCRAFT ON ITS PRESENT COURSE, TO WHICH THE PILOT REPLIED ?THANK YOU?. UPON ATC INQUIRY ABOUT HIS FLIGHT CONDITIONS HE REPORTED ?A LITTLE BIT OF PRECIPITATION AND LIGHT CHOP OR TURBULENCE?. SHORTLY THEREAFTER THE PILOT ADVISED WITHOUT GIVING REASON THAT HE WAS CHANGING HIS DESTINATION TO BOISE, ID (BOI). CONTROLLER ACKNOWLEDGED THE CHANGE AND ADVISED THE PILOT OF SCATTERED AREAS OF MODERATE PRECIPITATION ON HIS COURSE TO BOI.   PILOT THEN ADVISED ATC HE WAS ?MIN FUEL? AND THEN ?CRITICAL FUEL? STATING THAT HE MIGHT HAVE DEVELOPED A FUEL LEAK AND WAS TRYING TO FIND A SAFE PLACE TO PUT THE AIRCRAFT DOWN.  THE CONTROLLER OFFERED SEVERAL OPTIONS BOTH BEHIND AND AHEAD OF THE AIRCRAFT. THE LAST RECORDED CALL FROM THE AIRCRAFT WAS THE PILOT REPORTING ?ENGINE OUT?.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: The pilot’s failure to maintain proper airspeed and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall.
