Failure of the brake system O-rings on the left landing gear trunnion, which allowed the hydraulic fluid to drain from the left brake system, resulting in a runway excursion and impact with a fence.

Read the full NTSB narrative

The pilot reported a failure of the left brake during the landing roll. The airplane departed the runway surface and impacted a fence, which cause substantial damage to the empennage, right elevator, and horizontal stabilizers. Postaccident examination of the brake system revealed that the left brake master cylinder reservoir was completely empty. It was serviced and tested with no failure or leaks identified. Further examination of the brake system included the removal of the main landing gear pivot trunnion. It revealed that the O-rings, while not visibly damaged, were flat and stiff, which likely allowed the brake fluid to leak out from the main landing gear trunnion to the actuator interface joint when the landing gear was retracted.
