Probable cause

The pilot’s improper landing flare during the aborted takeoff, which resulted in a hard landing and a nose-over.

Findings · 3

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during takeoff, he applied right rudder to counteract the left turning tendencies of the airplane, but the airplane continued left of the runway centerline. He was unable to correct back to the runway centerline when the airplane was about 5 to 10 ft above the ground, so he decided to abort the takeoff and land on the grass left of the runway. During the landing, the airplane landed hard, the nose landing gear "dug" into the grass, and the airplane nosed over. The airplane sustained substantial damage to the wings and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

He was unable to correct back to runway centerline, about 5 to 10 ft above the ground, so he decided to abort the takeoff and land on the grass to the left of the runway. During the landing, the airplane landed hard and the nose landing gear "dug in" to the grass and the airplane nosed over. The airplane sustained substantial damage to the wings and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
