What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft was back taxiing on runway 20 for take-off. At approximately 2074 feet prior to reaching the threshold of runway 20, the aircraft veered to the right and exited the runway. The right main landing gear was first to contact the grass followed by the nose landing gear. Ground conditions were wet and muddy. The right main landing gear sunk in the mud. The nose gear sunk and collapsed in the mud. The left main landing gear remained on the runway. Due to the angle of the aircraft (caused by nose gear collapse and sinking in mud) both props struck the ground and sustained severe damage. Prior to FAA arrival, the aircraft was removed by the airport manager and placed in a t-hangar. There were no injuries reported.
