On November 20, 2014, at 1252 central standard time, a Beech 58P, N3689L, landed long and went off the end of the runway at Stinson Municipal Airport (SSF), San Antonio, Texas. The pilot, the sole occupant on board, sustained minor injuries. The airplane was substantially damaged. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Instrument meteorological conditions prevailed at the time of the accident, and an instrument flight rules flight plan had been filed. The flight originated from Wiley Post Airport (PWA), Oklahoma City, Oklahoma, at 1059, and was en route to SSF.At 1247, the pilot advised local control that he was 4 miles south of the airport and inbound on approach for landing. The controller instructed the pilot to circle and land on runway 14. He was given the wind conditions and told that there was "rain on the airport." A witness observed the airplane halfway down the runway and still airborne. The airplane touched down, ran off the end of the runway, and went through a barrier fence before coming to a stop on a service road. The left wing leading edge was crushed when it struck a fence post. The nose landing gear had collapsed.

The pilot told a Federal Aviation Administration inspector that his brakes had failed. The brakes were later tested and found to operate normally. Examination of the runway revealed evidence of hydroplaning.
