NTSB narrative
THE PILOT HAD MADE THREE PREVIOUS APPROACHES AND LANDINGS ON THE SAME RUNWAY ASSOCIATED WITH THE ACCIDENT DURING THE MORNING. SHORTLY AFTER THE FOURTH APPROACH WAS EXECUTED THE PILOT STATED THE AIRPLANE ENCOUNTERED A STRONG DOWN DRAFT. WHILE IN THE DOWN DRAFT THE AIRPLANE STRUCK 60 FOOT HIGH POWERLINES WHICH WERE APPROXIMATELY 1,200 FEET FROM THE THRESHOLD OF THE LANDING RUNWAY. THE AIRPLANE COLLIDED WITH THE AIRPORT PARKING RAMP AND SLID ONTO THE GRASSY CLEARWAY ADJACENT TO THE RAMP.
Probable cause
THE PILOT NOT MAINTAINING A PROPER GLIDEPATH TO THE LANDING RUNWAY.

- 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.
