Aircraft Overran Wet Runway at Ardmore Airport (N9719C)

Incident Overview and Conditions An aircraft operating under a special ferry permit with one engine inoperative attempted to land at Ardmore Airport. The accident occurred during darkness, with limited visibility due to fog. Rainfall of 0.61 inches was recorded at the airport between 1855LT and 0040LT, leaving the runway wet at the time of the incident. The aircraft touched down on the wet runway but encountered difficulties stopping within the remaining distance. It subsequently overran the runway and came to rest in a ditch. All three crew members evacuated safely, while the aircraft sustained damage beyond repair. ## Contributing Factors The official investigation identified hydroplaning on the wet runway as the probable cause, which prevented the aircraft from stopping within the available distance. Contributing factors included a poorly planned approach, misuse or failure to use flaps, inability to reverse thrust, a low ceiling, rain, and restricted vision caused by a dirty windshield.
