Landing and Runway Excursion
After an uneventful 30-minute instrument flight rules (IFR) flight, the business jet landed in the rain on a 4,311-foot-long runway. According to the pilot and corroborated by runway skid marks, the airplane touched down approximately 1,000 feet from the approach end of the runway. The pilot reported that braking action was initially normal and the anti-skid system cycled twice before it stopped functioning. Unable to slow the airplane using the emergency brakes, the aircraft continued off the departure end of the runway.
Post-accident Evidence
The airplane traveled through wet grass and a fence before coming to rest with the landing gear collapsed. A video of the landing roll showed a significant amount of water on the runway. Postaccident examination of the airplane revealed no mechanical anomalies with the brake or anti-skid systems. Marks on the runway indicated that the anti-skid system had been functional during the landing roll.
Stopping Performance
Stopping performance calculations estimated that the distance required to stop the airplane on the runway was approximately 4,127 feet. Given the touchdown point 1,000 feet from the approach end, the runway length remaining was about 3,311 feet—insufficient to bring the aircraft to a stop under the existing conditions.
Pilot Awareness
The pilot was aware of the runway length and weather conditions prior to departure and reported that he should not have accepted the trip.
