NTSB narrative
BOTH PILOTS REPORTED THAT THEY ENCOUNTERED A DOWNDRAFT DURING THE FINAL APPROACH WHICH CAUSED THE AIRPLANE TO DEVELOP A HIGHER THAN DESIRED SINK RATE. THE APPLICATION OF POWER FAILED TO ARREST THE SINK RATE BEFORE THE AIRPLANE TOUCHED DOWN APPROXIMATELY ONE FOOT SHORT OF THE RUNWAY. THE AIRPLANE CAME TO A STOP ABOUT 1,000 FEET DOWN THE RUNWAY, WITH ALL THREE LANDING GEAR COLLAPSED. THE PILOT SAID THAT HE HAD ENCOUNTERED LIGHT TO MODERATE TURBULENCE DURING THE APPROACH, AND HE WAS 'SHOOTING FOR THE END OF THE RUNWAY'.
Probable cause
THE PILOT'S IMPROPER INFLIGHT PLANNING/PREPARATION, AND HIS FAILURE TO ATTAIN THE PROPER TOUCHDOWN POINT. CONTRIBUTING TO THE ACCIDENT WAS THE DOWNDRAFT.

- 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 1992-08-09.
