The runway's downhill slope, the wet grass, the fence, and the embankment were factors. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - terrain condition - wet (contributing factor) - terrain condition - grass (contributing factor) - unsuitable terrain or takeoff/landing/taxi area - selected, pilot in command (cause) - terrain condition - downhill (contributing factor) - On ground/water collision with object, landing - roll - terrain condition - drop-off/descending embankment (contributing factor) - object - fence (contributing factor) ## Analysis The airplane was damaged when it went off the end of a grass runway during landing. The pilot reported that he touched down about 1/3 of the way down the 2,200 foot-long grass strip, applied the brakes and felt that the airplane was sliding. He attempted to stop by pumping the brakes. When he realized that he would not be able to stop the airplane before the end of the runway, he locked the left brake in an attempt to skid the airplane sideways to a stop. The airplane went off the end of the runway, down an embankment, and struck a fence. He stated that he was aware that the runway was wet prior to the flight and that the runway has a downhill slope in the direction used for the landing attempt. The pilot reported no mechanical problems with the airplane. ## Factual narrative The airplane was damaged when it went off the end of a grass runway during landing.
