NTSB narrative
The private pilot receiving instruction initiated the takeoff on runway 22. At approximately 40 mph, she raised the tail off the ground in preparation for liftoff. The airplane veered to the left, and the flight instructor took control and aborted the takeoff. The airplane struck a runway light before coming to a stop on the left side of the runway. The flight instructor said that as power was increased for takeoff, the right throttle was advanced slightly ahead of the left throttle, and this, in combination with the gusty crosswind, caused the airplane to veer left off the runway. The wind was from 180 degrees at 17 knots (19 mph), with gusts to 24 knots (28 mph). This would present a 40 degree left quartering headwind. The airplane was not equipped with Geisse safety gear. According to the Crosswind Component Chart contained in the Beech G18S 'Flight Handbook,' the maximum safe crosswind component was not exceeded.
Probable cause
Failure of the pilot receiving instruction to maintain directional control. Factors were a gusty crosswind, inadequate supervision by the flight instructor, and the runway light.

- 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.
