Aircraft Accident/Incident Report

Augusta, Kansas 67010
Saturday, July 21, 2012 11:20 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that the preflight run-up was uneventful and that the brakes worked normally at that time. After takeoff, she remained in the airport traffic pattern and returned for a full stop landing. The approach and landing were normal; however, during the landing roll, the brakes were completely ineffective. Upon reaching the end of the runway, the pilot thought that the airplane was still traveling too fast to safely turn onto the taxiway. She elected to overrun the end of the runway, and the airplane encountered a concrete culvert. A postaccident examination did not reveal any anomalies consistent with a brake system failure. However, the main landing gear tires did not exhibit any flat areas indicative of a skidding tire nor were any skid marks corresponding to the accident airplane observed on the runway pavement.

NTSB Probable Cause Narrative

The loss of brake effectiveness on landing roll for reasons that could not be determined because a postaccident brake system examination did not reveal any anomalies, which resulted in a runway excursion.
