WEST LIBERTY, IA, USA

Aircraft #1

N8221W

PIPER PA-28-180C

Analysis

The pilot reported the airplane made a normal touchdown on the grass airstrip. When he applied the brakes to stop, the airplane skid as if it was on ice. To avoid impacting a parked airplane and a fence located at the end of the runway, the pilot applied full power and full right rudder to turn the airplane. The airplane went into a bean field, and its left wing impacted a fence post. The pilot stated that the airstrip looked dry, but it was wet and muddy because the snow had recently melted leaving the ground very soft.
