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
Approach · IFR missed approach
Defining eventThe 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
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

The noninstrument-rated private pilot filed an instrument flight plan to an airport that was reporting night instrument meteorological conditions (IMC), which included ¼-mile visibility, fog, sky obscuration, and 100-foot vertical visibility. Radar track data showed that, upon arrival at the airport, the pilot flew the instrument lighting system approach and then attempted to execute a missed approach. During the missed approach, radar contact was lost and the airplane impacted the terrain. The postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.

The pilot's toxicology report indicated that gabapentin and duloxetine were found in the pilot's system, and both are disqualifying drugs for flight. The pilot did not report either of these disqualifying medications on his last medical certification examination. While both medications are sedating, a witness reported that the pilot was alert and energetic before the flight and showed no signs of sedation. Witness reports and findings from the wreckage examination are consistent with a loss of control event, and, based on the degraded visual reference conditions present about the time of the accident, it is likely that the pilot experienced spatial disorientation. Although it could not be determined what effect the use of the medications had on the pilot's performance during the high-workload IMC flight, their use could increase the chance of experiencing and responding inappropriately to spatial disorientation.

Probable cause

The noninstrument-rated pilot’s improper decision to fly a night instrument approach in instrument meteorological conditions, which resulted in the pilot’s spatial disorientation and loss of control of the airplane during an attempted missed approach.

  • 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, coordinates. 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.
