Factual narrative
BEFORE THE FLIGHT THE PILOT OBTAINED A WEATHER BRIEFING AND WAS INFORMED OF AN APPROACHING THUNDERSTORM WHICH WAS 10 MILES NORTHWEST OF THE AIRPORT. THE PILOT STATED THAT AFTER A NORMAL TAKEOFF HE CLIMED TO A ALTITUDE OF ABOUT 250 FT AGL, AT 70 KIAS, WHEN HE EXPERIENCED MODERATE TURBULENCE AND THE CLIMB LEVELED OFF. THE PLT THEN CHECKED THE ALTIMETER AND VERTICAL SPEED INDICATOR WHICH HE SAID INDICATED A DESCENT EVEN THOUGH HIS AIRSPEED AND ATTITUDE INDICATED THE ACFT SHOULD BE CLIMBING. UNABLE TO ARREST THE DESCENT, THE ACFT SETTLED INTO AN OPEN FIELD. THE REPORTED CHEYENNE WINDS AT 1959 MDT WERE FROM 340 DEGREES AT 25 KTS GUSTING TO 38 KTS. AT 2052 MDT THE WINDS WERE REPORTED TO BE FROM 020 DEGREES AT 8 KTS. THE THUNDERSTORM WHICH PASSED OVER CHEYENNE AT 1907 MDT WAS REPORTED TO BE A STORM OF LEVEL 1 INTENSITY. THE ELEVATION OFTHE ARPT WAS 6156 FT. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
