NTSB narrative
AFTER THE STUDENT PILOT DRAINED A SMALL AMOUNT OF FUEL FROM THE AIRCRAFT'S FUEL SUMP HE AND HIS TWO PASSENGERS ENPLANED FOR A LOCAL FLIGHT. AFTER THE ENGINE WAS STARTED FOR THE FLIGHT IT STOPPED FOUR TIMES WHILE TAXIING FOR TAKEOFF. A PASSENGER STATED THAT THE STUDENT PILOT USED THE FUEL PRIMER IN AN ATTEMPT TO KEEP THE ENGINE RUNNING. AFTER AN ENGINE RUN-UP THE PILOT TOOKOFF. THE ENGINE BEGAN SPUTTERING JUST AFTER TAKEOFF. THE AIRCRAFT COLLIDED WITH ELECTRICAL TRANSMISSION LINES AND IMPACTED THE GROUND. A POST CRASH FIRE ERUPTED AND DESTROYED THE AIRCRAFT.
Probable cause
STUDENT PILOTS FAILURE TO ADEQUATELY REMOVE MOISTURE FROM THE FUEL SYSTEM DURING HIS PREFLIGHT INSPECTION WHICH LED TO A LOSS OF ENGINE POWER DURING A CRITICAL PHASE OF FLIGHT.

- 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 1988-07-13.
