What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Aircraft attempted to land on runway 35R at cos. Pilot explained that after crossing threshold on speed and on centerline, aircraft began a flare; all appeared normal. The aircraft then was forced to the left edge of the runway as the right wing raised up, according to the pilot. Pilot said that something unknown then "clipped" the aircraft causing it to be pointed to the northwest. Pilot speculated that the "clip" was the impact of the left main gear off the edge of the runway, but the exact cause remains undetermined. He said he attempted a go-around but noticed a possible "delay" in engine response. The aircraft did not go around, and hit a stop sign on a service road running between runway 35R and taxiway echo. The pilot shut down the engine as the aircraft continued diagonally across taxiway echo and then across the unimproved airport property for approximately .34 miles. The aircraft then hit a chain-link fence, proceeded through it, and came to rest approximately 100 feet beyond the fence. Wind was reported by the air traffic controller as 100 degrees at 15 when the aircraft was cleared to land, according to personnel at the cos ATCT.

THE PILOT SHUT DOWN THE ENGINE AS THE AIRCRAFT CONTINUED DIAGONALLY ACROSS TAXIWAY ECHO AND THEN ACROSS THE UNIMPROVED AIRPORT PROPERTY FOR APPROXIMATELY .34 MILES. THE AIRCRAFT THEN HIT A CHAIN-LINK FENCE, PROCEEDED THROUGH IT, AND CAME TO REST APPROXIMATELY 100 FEET BEYOND THE FENCE.
