Cirrus Design Corp SR22 N462CP accident near Lakeview, Arkansas

Probable cause

The pilot’s loss of control during the takeoff roll for reasons that could not be determined because postaccident examination of the airplane did not reveal any anomalies that would have precluded normal operation.

NTSB analysis

During the takeoff roll on a grass runway, the airplane veered right and impacted trees and a fence. A check of the runway surface did not reveal any obstacles or reasons for the right turn. Examination of the airplane did not reveal any preimpact malfunctions with the airplane’s controls. The airplane was equipped with a Recoverable Data Module (RDM,) which records various aircraft parameters, including brake temperatures. The right brake temperature started at about 105 degrees Fahrenheit (F) and rose to a high of about 120 degrees F. The left brake temperature was not captured by the RDM, suggesting that the temperature sensor was not working at the time of the accident. Without the left brake sensor reading, a comparison of the left and right brake temperatures cannot be made; therefore, it cannot be determined if the pilot inadvertently applied the right brake during the takeoff roll.
