NTSB narrative
THE PILOT OF THE PA-32R-300 ELECTED TO TURN INTO A BOX CANYON DURING HIS EN ROUTE CLIMB TO CRUISE. AT THE TIME HE TURNED INTO THE CANYON, THE PILOT FELT THAT THE RATE OF CLIMB WOULD ASSURE CLEARANCE OF THE RIDGE AT THE END OF THE CANYON. AFTER ENTERING THE CANYON THE AIRCRAFT ENCOUNTERED AN AREA OF DOWNDRAFTS. THE DESCENDING AIR REDUCED THE RATE OF CLIMB TO AN EXTENT THAT WOULD NOT ALLOW THE AIRCRAFT TO OUTCLIMB THE RISING TERRAIN. BY THIS TIME THE PILOT FELT THAT, BECAUSE OF THE NARROWNESS OF THE CANYON, HE COULD NOT SUCCESSFULLY REVERSE COURSE. HE THEREFORE ELECTED TO CONTINUE UP THE CANYON, WHERE HE EVENTUALLY FLEW THE AIRCRAFT THROUGH A CONTROLLED IMPACT WITH THE TERRAIN.
Probable cause
THE PILOT'S POOR INFLIGHT DECISION. FACTORS INCLUDE DOWNDRAFTS AND A BOX CANYON.

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.
