NTSB narrative
THE ACFT LOST ENGINE POWER ABOUT 400 FT AGL DURING INITIAL CLIMB AFTER TAKEOFF AND THE PILOT INITIATED AN EMERGENCY FORCED LANDING ON A PUBLIC ROAD. THE ACFT WING IMPACTED THE POST OF A NARROW CATTLE GUARD ACROSS THE ROAD DURING LANDING GROUND ROLL AND THE ACFT SLID OFF THE ROAD. THE ENGINE QUIT AGAIN WHILE IT WAS BEING TESTED AFTER THE ACCIDENT. AN EXAM OF THE ENGINE FUEL SYSTEM REVEALED THE ENGINE FUEL PUMP VAPOR RETURN JET WAS PLUGGED WITH A SMALL PIECE OF BLACK, CRESCENT SHAPED, RUBBER MATERIAL. A NEW FUEL HOSE TO THE ENGINE FUEL PUMP, MADE OF BLACK RUBBER MATERIAL, WAS INSTALLED AT THE LAST ANNUAL INSPECTION.
Probable cause
THE IMPROPER MAINTENANCE/REPLACEMENT OF A FUEL HOSE AND THE BLOCKED FUEL VAPOR RETURN SYSTEM. A FACTOR RELATING TO THE ACCIDENT WAS THE CATTLE GUARD FENCE POSTS BESIDE THE ROAD.

- 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.
