NTSB narrative
AFTER THE AIRPLANE TOOK OFF, FUEL WAS FOUND TO BE LEAKING FROM THE AIRCRAFT. THE CFI CONTINUED TO OVERFLY ONE AIRPORT AND ATTEMPTED TO LAND AT THE DESTINATION AIRPORT. THE FUEL SUPPLY WAS BECOMING EXHAUSTED AND THE ENGINE RAN INTERMITTENTLY. THE AIRPLANE LANDED SHORT OF THE RUNWAY IN 20-KNOT WINDS. THE PILOT-IN-COMMAND REPORTED THAT POST-ACCIDENT INSPECTION REVEALED THAT THE RIGHT FUEL TANK CAP WAS 'CROSS-THREADED AND THERE EXISTED A ONE-HALF INCH GAP BETWEEN THE CAP AND THE WING.'
Probable cause
THE FAILURE OF THE PILOT-IN-COMMAND (CFI) TO PERFORM AN ADEQUATE PREFLIGHT INSPECTION OF THE AIRPLANE, INCLUDING THE PROPER SECURING OF THE FUEL CAP. THE PILOT'S FAILURE TO DIVERT TO THE NEAREST AIRPORT AFTER RECOGNIZING EXCESSIVE FUEL CONSUMPTION WAS A FACTOR IN THE ACCIDENT.

- 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.
