Incident Overview
According to the pilot, the airplane touched down approximately 1,000 feet down the 2,400-foot-long runway. The aircraft was unable to stop within the remaining distance, rolled off the end of the runway into the grass, and came to rest in the water. No further details about the aircraft type, registration, or occupants were provided.
Runway and Tire Examination
Following the incident, an examination of the runway revealed a 472-foot black skid mark leading to the left main landing gear. No skid mark was observed leading to the right main landing gear. Inspection of the tires showed that the left main tire was flat and had a hole, indicating wear from braking. The right tire was fully inflated and showed no signs of excessive wear.
Hydraulic Fluid Leak
Investigators found indications of hydraulic fluid leakage on the right main gear leg at the pivot joint. This joint allows movement of the gear leg during retraction.
Pilot Report
The pilot reported that recent brake maintenance had been performed on the airplane. No other information regarding the nature or extent of the maintenance was disclosed.
Conclusion
The source does not state a probable cause for the incident. The investigation documented the late touchdown, the asymmetric braking evidence, and the hydraulic fluid leak, but no causal analysis was provided.
