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

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

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 pilot and his pilot-rated passenger departed for a night cross-country flight. They were receiving visual flight rules advisories and had been assigned a discrete transponder code. They were climbing to an altitude of 9,500 feet msl, and were at 9,100 feet msl when radio and radar contact were lost. The last recorded radio transmission from the pilot was, 'We're in a flat (blocked out), we're going to lose it dad.' A search was initiated, and the airplane and its occupants were found the next day. The cloud bases in the area were reported by other pilots to be about 7,100 feet msl, with tops about 13,000 feet. The light conditions were reported to be 'dark night' with little surface ambient light in the sparsely populated area. The pilot's logbook was examined, and no indication was found of the pilot having flown during the 90-day period preceding the accident. Neither the pilot nor the pilot-rated passenger had an instrument rating. Postaccident examination of the airplane did not reveal any preexisting deficiencies.

Probable cause

THE PILOT'S FAILURE TO MAINTAIN AIRCRAFT CONTROL. FACTORS IN THIS ACCIDENT WERE: 1) THE DARK NIGHT AND LACK OF AMBIENT LIGHT WHICH RESULTED IN THE PILOT INADVERTENTLY FLYING FROM VISUAL METEOROLOGICAL CONDITIONS INTO INSTRUMENT METEOROLOGICAL CONDITIONS; 2) THE PILOT'S LACK OF INSTRUMENT FLIGHT EXPERIENCE, AND 3) SPATIAL DISORIENTATION.

  • 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 1993-11-22.
