NTSB narrative

THE ACFT LOST POWER DURING A NORMAL CLIMB ON A PERSONAL TRIP. THE PRIVATE PLT NOTICED A DROP IN FUEL FLOW PRESSURE AND SMELLED FUEL. THE PLT THEN SELECTED BOOST PUMP ON BUT THE PRESSURE STAYED LOW. THE PLT ELECTED TO MAKE A FORCED LANDING AND SELECTED A FIELD. THE ACFT OVERFLEW THE FIELD AND IMPACTED IN A TREE FILLED SWAMP. POST ACCIDENT EXAM OF WRECKAGE DID NOT REVEAL ANY EVIDENCE TO EXPLAIN THE LOSS OF POWER OR THE FUEL ODOR.

  • 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.
  • API snapshot SHA-256: f460daaf155e32669a3422d3af70e85b35fbf32186ead3950c99dcf14bb49c6d; retrieved 2026-09-23T13:14:31.294Z.
