What happened
The pilot was operating a Cessna 340A when he attempted to land on Runway 19. The weather conditions at the time included moderate rain, resulting in a wet runway surface. The specific runway had dimensions of 4,650 feet in length and 75 feet in width.
According to the pilot's statement, the aircraft touched down approximately 25% into the runway, leaving roughly 3,480 feet of remaining distance. Despite this ample space, the pilot reported being unable to achieve effective braking prior to the aircraft running off the end of the paved surface. Examination of the tire damage and the condition of the runway stripes indicated that hydroplaning was a contributing factor in the loss of braking capability.
The investigation
Investigators reviewed the physical evidence left at the scene, specifically focusing on the state of the tires and the markings on the runway. The pattern of wear on the tires combined with the disturbance of the runway stripes provided clear indicators that the wheels had lost traction due to water buildup, confirming hydroplaning as a significant element in the accident sequence.
Findings
The primary finding was the pilot's inability to stop the aircraft within the available runway length. The wet conditions, combined with the specific landing location on the strip, led to a loss of friction between the tires and the runway surface. This resulted in the aircraft continuing its momentum past the end of the runway.
