Accident Overview
During the initial takeoff roll, after the aircraft had traveled between 100 and 150 feet, the right-side brake seized. This caused the aircraft to veer sharply to the right. The aircraft departed the runway and entered a muddy area beside the runway. As a result of the muddy terrain, the nose gear collapsed and the aircraft nosed down.
Pilot Observations
The pilot reported that skid marks from the right tire were visible on the runway surface, measuring approximately 200 feet in length. Additionally, the pilot noted that the pins securing the brake pad were loose. This looseness allowed the brake pad to move from its intended position, leading to the seizure of the brake.
Contributing Mechanical Condition
According to the pilot's report, the loose condition of the brake pad pins permitted movement of the pad, which in turn caused the brake to seize. No other factors were identified in the report.
