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
Part 91: General Aviation
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
En route · cruise
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
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
Destroyed

NTSB narrative

DURING A VFR CROSS COUNTRY FLIGHT, THE PILOT HAD CONTACTED APPROACH CONTROL AND ADVISED THE CONTROLLER THAT HE WAS UNFAMILIAR WITH THE AREA AND REQUESTED VECTORS. THE CONTROLLER RESPONDED TO THE PILOT BY INFORMING HIM TO REMAIN VFR AND UTILIZE HIS OWN NAVIGATION. RADAR DATA INDICATES THAT THE AIRPLANE WAS HEADING TOWARD MOUNTAINOUS TERRAIN, AT A LEVEL ALTITUDE, AND 153 KNOTS WHEN THE TARGET WAS LOST NEAR THE MOUNTAINS. WRECKAGE DOCUMENTATION INDICATES THAT THE AIRPLANE COLLIDED WITH THE MOUNTAINOUS TERRAIN AT A HIGH SPEED AND ON THE APPROXIMATE HEADING AND ALTITUDE AS THE LAST RADAR TARGET. THE WRECKAGE WAS LOCATED AT THE 3,200-FOOT LEVEL OF A MOUNTAIN. A WITNESS IN THE AREA REPORTED THAT THE MOUNTAINS WERE COMPLETELY OBSCURED WITH CLOUDS AND VISIBILITY WAS LIMITED. NO EVIDENCE WAS FOUND TO INDICATE A MECHANICAL FAILURE OR MALFUNCTION.

Probable cause

THE PILOT'S CONTINUED VFR FLIGHT INTO INSTRUMENT METEOROLOGICAL CONDITIONS, AND HIS FAILURE TO MAINTAIN CLEARANCE FROM THE TERRAIN. FACTORS IN THE ACCIDENT WERE THE MOUNTAINS AND THE CLOUDS.

  • 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 1995-06-21.
  • API snapshot SHA-256: acba00d64ddd66b8760e7faee064db3b4e8c0d8312cd9dcec2708efc02e83457; retrieved 2026-09-20T23:44:05.261Z.
