Flight and Landing Information
The pilot initiated the flight with the flaps inoperative and stowed in the up position. The landing was attempted on runway 34, which was wet at the time, with precipitation present in the area. The pilot later acknowledged that she did not calculate the required landing roll distance for the wet runway conditions.
Accident Sequence
Upon touchdown, the aircraft hydroplaned along the runway surface, losing directional control. It continued beyond the departure end of the runway and entered a muddy area. The aircraft then pitched forward onto its nose, causing the nose gear to collapse.
Post-Accident Findings
Post-accident examination revealed damage to the propeller assemblies and both engines. The aircraft's Pilot Operating Handbook includes a cautionary note in its Safety Information Section regarding landings on runways covered by water.
