What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot was on an IFR flight plan from little rock, ar (hot) to Point Lookout, MO (plk). Pilot requested and was given a GPS approach to runway 29 by sgf ATC. There were thunderstorms in the area and it had been raining just prior to landing at plk. During landing, the wings changed to a tail wind. The pilot reported the aircraft hydroplaned and he was unable to stop. The pilot stated the aircraft was just about stopped when it went off the end. Post accident investigation revealed no skid marks on runway, which would indicate hydroplaning. There were marks in the gravel after the aircraft left the hard surface. The rain made it difficult to determine if the tires were skidding or rolling at that Point. There is approximately 12 feet of gravel from the end of the hard surface to the edge of a 45 degree decline, which drops approximately 75 feet and is covered with rocks ranging in size from one to two feet in diameter. After the aircraft left the gravel, the decline was too steep to stop the aircraft.
As the FAA filed it
(-23) PILOT WAS ON AN IFR FLIGHT PLAN FROM LITTLE ROCK, AR (HOT) TO POINT LOOKOUT, MO (PLK). PILOT REQUESTED AND WAS GIVEN A GPS APPROACH TO RUNWAY 29 BY SGF ATC. THERE WERE THUNDERSTORMS IN THE AREA AND IT HAD BEEN RAINING JUST PRIOR TO LANDING AT PLK. DURING LANDING, THE WINGS CHANGED TO A TAIL WIND. THE PILOT REPORTED THE AIRCRAFT HYDROPLANED AND HE WAS UNABLE TO STOP. THE PILOT STATED THE AIRCRAFT WAS JUST ABOUT STOPPED WHEN IT WENT OFF THE END. POST ACCIDENT INVESTIGATION REVEALED NO SKID MARKS ON RUNWAY, WHICH WOULD INDICATE HYDROPLANING. THERE WERE MARKS IN THE GRAVEL AFTER THE AIRCRAFT LEFT THE HARD SURFACE. THE RAIN MADE IT DIFFICULT TO DETERMINE IF THE TIRES WERE SKIDDING OR ROLLING AT THAT POINT. THERE IS APPROXIMATELY 12 FEET OF GRAVEL FROM THE END OF THE HARD SURFACE TO THE EDGE OF A 45 DEGREE DECLINE, WHICH DROPS APPROXIMATELY 75 FEET AND IS COVERED WITH ROCKS RANGING IN SIZE FROM ONE TO TWO FEET IN DIAMETER. AFTER THE AIRCRAFT LEFT THE GRAVEL, THE DECLINE WAS TOO STEEP TO STOP THE AIRCRAFT.
