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

Approach · IFR initial approach
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 collision with terrain/water
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Destroyed

NTSB narrative

WHILE EN ROUTE FROM SACRAMENTO TO ARCATA, CA, THE PLT CONTACTED ARTCC & FILED AN IFR FLT PLAN. AS HE WAS APCHG THE DESTN AT 10,000', HE REQUESTED A LOWER ALT. HE WAS CLEARED TO DSCND TO 8000'. HE WAS THEN CLEARED FOR AN ILS RWY 32 APCH TO AN UNCTLD ARPT AT ARCATA WITH A RESTRICTION TO REMAIN AT 8000' UNTIL CROSSING THE YAGER INTXN. THE PLT BGN HIS DSCNT EARLY & CROSSED THE YAGER INTXN AT 6700. THE ACFT DSCNDD BELOW RADAR COVERAGE AT 5300'. RADAR SVC WAS TERMINATED & THE PLT WAS INSTRUCTED TO CONTACT THE ARCATA FSS. HE CONTACTED THE FSS STATION & WAS ADZD THE WX WAS PARTIALLY OBSCD, 400' BKN, 1500' BKN, 2400' OVC, 3 MI VIS. THE PLT ACKNOWLEDGE & SAID HE WAS IN THE CLOUDS AT 3200', THEN THERE WAS NO FURTHER CONTACT WITH THE ACFT. A SEARCH WAS INITIATED & THE ACFT WAS FOUND WHERE IT HAD CRASHED ALONG THE ILS COURSE LINE ABOUT 18 MI SHORT OF THE RWY. IMPACT OCCURRED ON HILLY/MOUNTAINOUS TERRAIN AT AN ELEV OF ABOUT 2750'. THE MIN DSCNT ALT FOR THAT SEGMENT OF THE APCH WAS 5200'.

Probable cause

THE PILOT'S IMPROPER USE OF IFR PROCEDURES BY FAILING TO MAINTAIN THE MINIMUM DESCENT ALTITUDE FOR THE SEGMENT OF THE APPROACH THAT HE WAS FLYING. THE HILLY/MOUNTAINOUS TERRAIN WAS A RELATED FACTOR.

  • 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.
