 j. There was approximately 5,950 feet of useable runway remaining after touchdown.

k. There was standing water on the runway from an extended period of heavy rain.

l. All tires, Including the nose wheels, exhibited definite evidence reverted rubber type hydroplaning,

m. Evidence on the runway indicated hydroplaning existed from the point of touchdown to the end of the runway for the right main gear.

n The coefficient of friction between the tire of the landing gear and the runway surface was less than 0,15 as little or no deceleration forces we felt by the crew or the passengers.

O. At the landing weight and speed of the aircraft at touchdown with the existing runway conditions, more than the remaining useable runway length was necessary to stop the aircraft.

p. The passengers and crew evacuated the aircraft without major difficulty. Probable Cause.

The Board determines that the probable cause of this accident was hydroplaning of the landing gear wheels which precluded braking effectiveness.

The Board's recommendation to the Federal Aviation Agency and the Administrator's reply to that recommendation is appended as Attachment #4.
