NTSB narrative

During cruise flight the pilot experienced an increase in engine noise before the engine suddenly lost power. While the fuel status and tank indications were normal, he attempted to restart the engine three separate times without success. The pilot reported to air traffic control that the engine had failed and that he would be conducting an emergency landing into the Gulf of Mexico. The pilot and passengers were able to egress the airplane and held onto a crab pot buoy. The occupants of the airplane were rescued by the United States Coast Guard the next morning. After impact, the airplane sank and was not located.

Probable cause

A total loss of engine power for undetermined reasons.

  • 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 2009-10-10.
  • API snapshot SHA-256: 44de9e25398bb37c7b333df324b24bae6a0114d3a34d616da4820c371abb3828; retrieved 2026-09-15T13:23:55.386Z.
