- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

- 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
- In flight encounter with weather
- 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
- Visual flight rules (VFR) flight into instrument meteorological conditions (IMC)
- 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 CFI RECEIVED A FSS WEATHER BRIEFING FORECASTING SNOW SHOWERS BOTH EN ROUTE AND ON THE RETURN LEG OF THE FLIGHT. WHILE RECEIVING VECTORS DURING THE RETURN LEG, THE FLIGHT ENCOUNTERED HEAVY SNOW SHOWERS. THE DUAL STUDENT FLEW WHILE THE CFI FILED AND OBTAINED IFR CLEARANCE. THE PLANE FLEW FOR 4 MINUTES THROUGH HEAVY SNOW SHOWERS DURING THE CLEARANCE PROCEDURES. BOTH PILOTS SAID THE ENGINE QUIT. THE DUAL STUDENT ENTERED EMERGENCY DESCENT WHILE THE CFI ADDED CARBURETOR HEAT AND ATTEMPTED AN ENGINE RESTART, TO NO AVAIL. WHEN THE STUDENT SAID HE SAW THE TERRAIN, THE CFI TOOK THE FLIGHT CONTROLS AND COMPLETED AN EMERGENCY LANDING. AT TOUCHDOWN, THE NOSE WHEEL COLLAPSED IN THE PLOWED FIELD. THE PLANE SLID TO REST WITH A DAMAGED FUSELAGE AND LEFT WING. A POSTACCIDENT INSPECTION BY AN FAA INSPECTOR REVEALED AN ICE BUILDUP IN THE CARBURETOR AIR INDUCTION SYSTEM.
Probable cause
FAILURE OF THE CFI TO UTILIZE CARBURETOR HEAT PRIOR TO THE INDUCTION ICING AND POWER LOSS. CONTRIBUTING TO THE ACCIDENT WAS THE CFI'S CONTINUED VFR FLIGHT INTO KNOWN AND FORECAST INSTRUMENT METEOROLOGICAL CONDITIONS.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1989-12-02.
