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
Maneuvering
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
Airframe, component or system failure
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

Cause areas

  • Pilot in command › Aircraft control, not maintained
  • Pilot in command › Spatial disorientation
  • Pilot in command › VFR flight into imc, attempted

NTSB narrative

A witness heard an aircraft fly overhead but was unable to see it due to low clouds and misting precipitation. Another witness saw the airplane break out of the bottom of the overcast, accompanied by increased engine sounds and falling parts, which had separated from the aircraft. He estimated the ceiling to be about 400 feet above ground level. The aircraft was not equipped for IFR flight and the pilot did not possess an instrument rating. The right wing separated from the aircraft and was located approximately 100 feet from the main wreckage. The empennage section also separated from the fuselage, and, the horizontal and vertical stabilizers had separated from the empennage. Examination of the wreckage disclosed that the fracture surfaces exhibited overload characteristics, and no preimpact malfunctions or failures were found with the control system. The pilot's toxicological results were positive for quinine. The side effects of quinine can include disturbances of vision, hearing, and balance. Disturbances of balance have been noted even at low doses, and the use of quinine by pilots is usually contraindicated, as it may contribute to spatial disorientation under some conditions.

Probable cause

The pilot's attempt to continue VFR flight in instrument conditions, which led to his spatial disorientation and in-flight loss of aircraft control, and, resulted in a pilot-induced overload failure of the airframe. The pilot's use of quinine may have been a factor in this accident.

  • 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.
