Probable cause

The loss of brake control due to the fracture of the front brake pawl engagement spring, which resulted in a runway overrun.

NTSB narrative

The pilot reported that, following a normal landing, he applied the brakes and that he then released the brakes as the airplane decelerated to allow for brake cooling. As the airplane passed the 4,000-foot-remaining sign, the pilot reapplied the brakes but noted no braking action. The airplane subsequently overran the departure end of the runway. Postaccident examination of the airplane revealed that the spring that allows the front brakes to engage a brake pawl was fractured, which resulted in the deactivation of the front brake pedals and the subsequent runway overrun.

Analysis
