## Probable cause

The pilot’s failure to maintain directional control of the airplane during takeoff.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Takeoff: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Diamond Aircraft Ind DA 40, 12 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=2990002), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md)

## Analysis

The pilot reported that, during the takeoff roll, the airplane drifted left, and he applied rudder input to correct. The pilot subsequently reduced power to abort the takeoff, and the airplane departed the runway surface, into the gravel. The airplane collided with a runway sign, resulting in substantial damage to the left wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
