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
In flight encounter with weather
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

The solo private certificated pilot was en route to a private airport to attend a fly-in for homebuilt aircraft owners/builders. Visual meteorological conditions prevailed at the airplane's point of departure, but instrument meteorological conditions were reported along the pilot's route of flight. A friend said that accident pilot had attempted the same flight earlier in the day, but was unable to reach the airport due to low clouds and fog. Several residents in the vicinity of the accident site reported low clouds, fog, and reduced visibility in the area at the time of the accident. Ear witnesses reported hearing what sounded like a low flying airplane to the east, over a large lake. The witnesses said that as the airplane's engine sound increased, they heard a sudden impact, and the engine noise stopped abruptly. The witnesses consistently reported that they were not able to see the airplane due to very low visibility in mist and fog, and that the accident airplane's engine appeared to be producing full power prior to striking the water. Search and rescue personnel located the submerged airplane wreckage, and discovered the pilot's body inside, still restrained within the pilot's seat.

Probable cause

The pilot's continued VFR flight into instrument meteorological conditions, and his failure to maintain terrain clearance. Factors associated with the accident were fog and low ceilings.

  • 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.
