Aircraft involved
Probable cause & findings
A failure of the right brake caliper bolts during landing, which resulted in a runway excursion and subsequent impact with terrain.
Factual narrative
The pilot reported that during the landing roll on a gravel-covered airstrip, the airplane veered left, went through an embankment, and came to rest upright. A postaccident examination of the airplane revealed the right brake caliper bolts failed in overload. The lower bolt was broken in half, the upper bolt was not located, and the brake caliper was located in brush. Given that the airplane is routinely operated from rough, uneven, gravel-covered, off airport sites, it is likely that the brake caliper and bolts sustained impact damage, resulting in the failure of the attachment hardware.
