NTSB narrative
THE PILOT ATTEMPTED A TAKEOFF TO THE WEST WITH 900 FEET OF USABLE RUNWAY, WITH WINDS REPORTED AT 270 AT 15 KNOTS GUSTS TO 25 KNOTS. THE AIRPLANE DID NOT LIFT OFF AND IMPACTED A ROW OF 15 FOOT TALL SPRUCE TREES AT THE END OF THE TURF RUNWAY. A WEATHER REPORTING STATION, OLATHE, JOHNSON COUNTY AIRPORT, STATED WINDS OF 15 KNOTS, WITH GUSTS TO 25 KNOTS OUT OF THE WEST, 30 MINUTES AFTER THE ACCIDENT. AN FAA INSPECTOR REPORTED STRONG, GUSTY, SHIFTING WINDS THROUGHOUT THE AREA ON THE DAY OF THE ACCIDENT. THE PILOT SAID HE 'SUSPECTED WINDSHEAR.'
Probable cause
The pilot's improper weather evaluation. A factor was the pilot's inadequate compensation for the wind conditions.

- 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.
