NTSB narrative
According to the pilot the airplane lost engine power shortly after takeoff. Efforts by the pilot to restart the engine were unsuccessful. During the forced landing, the airplane collided with trees in an orange grove. Examination of the downed airplane revealed that the ribs of the right wing were bent, and the fuselage was buckled. Further examination revealed the lower gasket on the glass gascolator bowl was not aligned. The examination also disclosed that the glass gascolator bowl was dry and cracked. The maintenance performed on the airplane was an annual inspection which was completed 20 hours before the accident flight on October 23, 2003.
Probable cause
The loss of engine power due to fuel starvation resulting from a crack in the gascolator bowl.

- 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.
