NTSB narrative
The pilot said that he noted 10 gallons on 'each side' prior to initiating an approach. He said that about five minutes later the left engine lost power and about three minutes after that the right engine also sustained a loss of power. The damage to the airplane occurred during an undershoot to the intended runway. Emergency response individuals found no usable fuel in the airplane's fuel tanks. The pilot said that the accident might have been prevented by, 'Visual inspection of all fuel tank with calibrated device.'
Probable cause
Inadequate preflight planning/preparation, which resulted in fuel exhaustion.

- 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 1997-12-09.
