Incident Overview
During arrival, winds were reported from 350 to 360 degrees at 20 knots gusting to 25 knots. While landing, the wind was from 360 degrees at 21 knots. The aircraft's maximum demonstrated crosswind capability was 22 knots.
Sequence of Events
The pilot reported that during the landing, the power levers were retarded to idle, then to reverse. While entering reverse, the aircraft swerved to the left, away from the crosswind. The pilot then advanced the throttles out of reverse to less than flight idle. At that time, the aircraft swerved to the right. The power levers were again reversed and brakes were applied. However, the aircraft veered off the right side of the runway.
Aftermath
The aircraft continued into mud, the nose gear collapsed, and both propellers were damaged. The pilot did not feather the engines until after both propellers had stopped turning. The right propeller was found in the full feathered position; the left propeller had not feathered.
Propeller Examination
Removal of the right propeller dome revealed no apparent abnormalities or internal damage. There was evidence that the left propeller had gone beyond full reverse on impact. No preimpact failure was found.
