NTSB narrative
THE PILOT OF THE RENTED CESSNA 150 MADE A NUMBER OF PASSES OVER THE ELK HUNTING CAMP IN AN AREA WERE THE DENSITY ALTITUDE WAS OVER 7000 FEET. HE REPORTED THAT, ALTHOUGH THERE WAS VERY LITTLE TURBULENCE IN THE AREA, THE WINDS MUST HAVE BEEN FAIRLY STRONG BECAUSE THE GROUNDSPEED OF THE AIRCRAFT WAS SIGNIFICANTLY DIFFERENT ON EACH PASS, DEPENDING ON THE DIRECTION THE AIRCRAFT WAS HEADING. ON THE LAST PASS, THE PILOT ADDED POWER BUT WAS UNABLE TO OUTCLIMB THE RISING TERRAIN. HE REPORTED THAT THE ENGINE SEEMED TO BE RUNNING FINE, BUT THE AIRCRAFT WAS DESCENDING AT 800 FEET PER MINUTE WHILE AT FULL POWER.
Probable cause
THE PILOT'S POOR INFLIGHT DECISION. FACTORS INCLUDE MOUNTAINOUS/HILLY TERRAIN, TREES, HIGH DENSITY ALTITUDE, AND DOWNDRAFTS.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
