Incident Overview
An instrument flight rules (IFR) flight neared its conclusion when the pilot of a multi-engine airplane was given radar vectors for an instrument approach in instrument meteorological conditions (IMC). During the descent, the pilot observed an area of patchy fog over the approach end of the runway and leveled off to avoid it.
Landing and Runway Overrun
The pilot landed the airplane with approximately 3,000 feet of the nearly 6,000-foot-long runway remaining. During the landing roll, the pilot used a combination of wheel braking and the beta range of the propellers. The pilot reported feeling the airplane hydroplaning. The airplane subsequently overran the end of the runway, onto the adjacent grass and mud, collapsing the nose landing gear and impacting terrain.
Aircraft Damage
The airplane sustained substantial damage to the forward fuselage.
Pilot Statement
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Weather Conditions
The airport's automated weather observation station reported that about the time of the accident, the wind was from 270° at 3 knots, visibility was ½ statute mile with fog, and an overcast ceiling at 300 feet. The pilot was landing on runway 23.
