Landing and Braking Incident
After touchdown during a full-stop landing, the student pilot was instructed to apply the brakes. When the student failed to respond, the certified flight instructor (CFI) applied the brakes. As the brakes were engaged, the aircraft veered to the left.
Corrective Actions
The CFI corrected the veer by applying full right rudder and brake. Simultaneously, the CFI instructed the student to release the controls. Despite these efforts, the aircraft departed the left side of the runway and came to rest in a drainage ditch.
Post-Incident Findings
An inspection of the brakes revealed no mechanical problems. The CFI noted that this aircraft had different braking characteristics than older model Cessnas.
