Landing and Initial Deceleration
Upon completing a cross-country flight, the captain of a turbojet aircraft initiated landing. During the rollout, the captain used aerodynamic braking and thrust reverse to decelerate the airplane to approximately 60 knots. The captain then allowed the airplane to continue rolling toward the end of the runway, near the location of the owner/co-pilot's hangar.
Loss of Braking
With about 4,000 feet of runway remaining, the captain applied the brakes. No braking action was noted. The airplane continued off the end of the runway, through a fence and a block wall, and into a parking lot. During the excursion, the left wing was severed.
Post-Crash Fire
A post-crash fire ignited, consuming approximately half of the airplane. Emergency braking procedures were not employed. The crew reported that they were unable to shut down the engines.
Crew Coordination and Experience
The co-pilot lacked experience in the aircraft. Crew coordination during the approach, landing, and subsequent emergency was ineffective.
Investigation Findings
Examination of the braking and hydraulic systems failed to pinpoint a malfunction. The airplane traveled approximately 11,000 feet from the point of touchdown to its final resting position.
