What happened
The accident occurred during the landing phase of flight when the airplane left the paved surface and collided with nearby trees. Following the impact, the pilot provided an account of the events leading up to the crash, specifically noting that the right brake failed to function as expected during the rollout.
The investigation
A thorough postaccident examination of the aircraft was conducted to determine the mechanical status of the braking system. Inspectors discovered that the master cylinder associated with the right brake contained no hydraulic fluid whatsoever. Despite this complete depletion, there were no visible signs of a leak within the brake system components.
Findings
The airplane had accumulated approximately 32 hours of flight time since its last annual inspection. The absence of hydraulic fluid in the right brake master cylinder, combined with the lack of evidence for an external leak, suggests a failure within the sealed system or internal leakage that did not manifest externally. This mechanical deficiency directly contributed to the inability to stop the aircraft on the runway.
Safety message
Regular maintenance inspections are critical for identifying potential fluid loss or component failures before they lead to accidents. Pilots should be aware of brake performance during landing rollouts and report any anomalies immediately.
