Incident Overview
During the landing rollout, the pilot observed an aircraft parked on the right side of the runway near the departure end. Concerned that the aircraft was not decelerating as quickly as desired and that there would be insufficient room to pass, the pilot pulled the parking brake handle. The aircraft then began to pull to the left.
Sequence of Events
The aircraft departed the shoulder of the narrow runway and proceeded down a grade of 4 to 5 feet. The left wing subsequently contacted the ground, causing the aircraft to enter a sideways slide.
Examination
A post-incident examination revealed no anomalies with the brake system. A mechanic stated that if the parking brake is used while the aircraft is in motion, one brake will almost certainly lock up before the other.
