NTSB narrative

The pilot of the tailwheel-equipped airplane reported that, during a touch-and-go landing on a turf airstrip, he applied power for takeoff, the airplane drifted left, and he applied right aileron and left rudder. As the airplane accelerated, it began drifting farther left until it departed the runway onto the grass. The pilot reported that the airspeed was about 60 mph and that he felt he could fly out of the situation. However, he realized the airplane was approaching a hill with trees and a house too quickly and would not clear the trees. He then applied right rudder and the airplane turned 90° toward the runway and began to skid. The airplane skidded across the runway and hit a ditch. The left landing gear collapsed followed by the right, and the airplane skidded to a stop.

The airplane sustained substantial damage to the left wing and fuselage.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

A review of recorded data from the automated weather observation station located about 14 miles southwest of the accident site revealed that, at 1255, the wind was from 190° at 13 knots, gusting to 21 knots. The airplane landed on runway 17.

Probable cause

The pilot’s failure to maintain directional control during takeoff, which resulted in a runway excursion.

  • 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, coordinates. 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.
