Youngstown - Columbia

The pilot had computed landing performance information for a landing on a wet runway with anti-skid; sufficient runway surface was available. Touchdown was normal, however during the braking process, the airplane started to fishtail and the pilot believed that the anti-skid system had failed. Therefore, the pilot turned the antiskid system off and continued the rollout with normal braking. The airplane went off the departure end of runway 05 and sustained substantial damage. Performance data indicated more runway surface was required for a safe landing on a wet runway without anti-skid assistance. The braking sequence of events described by the pilot resembled dynamic hydroplaning where there was a complete loss of braking effectiveness rather than an anti-skid malfunction. An examination of the airplane failed to disclose any mechanical problems.

Narrative Report

On July 2, 1991 at 06:56 PM, Youngstown - Columbia experienced a crash involving Learjet 23, operated by Kalitta Charters - Kalitta Services, with the event recorded near Columbia-Mount Pleasant-Maury County Tennessee.

The flight was categorized as cargo and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) crash site.

2 people were known to be on board, 0 fatalities were recorded, 2 survivors were identified or estimated. This corresponds to an estimated fatality rate of 0.0%.

Crew on board: 2, crew fatalities: 0, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.

The listed crash cause is other causes. The pilot had computed landing performance information for a landing on a wet runway with anti-skid; sufficient runway surface was available. Touchdown was normal, however during the braking process, the airplane started to fishtail and the pilot believed that the anti-skid system had failed. Therefore, the pilot turned the antiskid system off and continued the rollout with normal braking. The airplane went off the departure end of runway 05 and sustained substantial damage. Performance data indicated more runway surface was required for a safe landing on a wet runway without anti-skid assistance. The braking sequence of events described by the pilot resembled dynamic hydroplaning where there was a complete loss of braking effectiveness rather than an anti-skid malfunction.
