Narrative:The pilot reported that, during the descent for an instrument approach in instrument meteorological conditions, he saw an area of patchy fog over the approach end of the runway and leveled off to avoid the fog. He landed the airplane with about 3,000 ft of the nearly 6,000-ft-long runway remaining and felt the airplane hydroplaning while using a combination of wheel braking and the beta range of the propellers. The airplane subsequently overran the end of the runway onto grass and mud, which resulted in the nose landing gear collapsing. The airplane sustained substantial damage to the forward fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable Cause:
Probable Cause: The airplane hydroplaning while landing on a wet runway, which degraded its braking capability and resulted in a runway overrun onto grass and mud and the nose landing gear collapsing. Contributing to the accident was the pilot's improper decision to land the airplane until it was near the runway midpoint due to fog over the approach end of the runway.
