- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Maneuvering · turn to reverse direction
- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Loss of control in flight
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Stall
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The two pilots we en route home after a trip to the west coast. Two witnesses, hiking near the Continental Divide, heard an airplane approaching. They saw the airplane coming towards them "at eye level." It seemed to be stationary, then it banked hard to the right and went straight down. The accident took place at an elevation of 11,418 feet msl. The elevation of that portion of the Continental Divide is 11,530 feet msl. Later engine disassembly and examination disclosed no anomalies. Weather observed at a remote AWOS facility, located approximately 1 mile east of the accident site, was used to compute an estimated density altitude of 14,300 feet msl. According to the 1984 Cessna 172P Skyhawk "Information Manual," the airplane's service ceiling is 13,000 feet.
Probable cause
the pilot's failure to maintain airspeed which resulted in a stall, and his decision to conduct flight beyond the performance capability of the aircraft. A contributing factor was the high density altitude, and an inadvertent stall.

- 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, coordinates. 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.
