NTSB narrative
The instructor stated that during the landing rollout the student applied violent pressure to the right brake, which moved the nose about 70 degrees to the right, and the aircraft entered a skid toward the right side of the runway. The instructor said that he then immediately took control of the airplane, but the student maintained his feet on the brakes, and the airplane collided with a runway sign, incurring substantial damage. The student stated that it is possible that he could have been just using the right brake to stop the aircraft, and that upon application of the brakes the aircraft started skidding. The student said he then transferred controls to the instructor, but the aircraft was traveling too fast, and exited into the grass where one wing hit a sign. Postaccident examinations of aircraft's steering and brake systems did not reveal any abnormalities to the aircraft, or its systems prior to the accident.
Probable cause
the dual student's improper use of the brakes and the flight instructor's inadequate supervision which resulted in a loss of directional control and a subsequent ground swerve during which the aircraft exited the runway and collided with a runway sign.

- 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. 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.
