What happened
On July 31, 2024, at approximately 0720 central daylight time, a Piper PA-28-180, registration N903US, was destroyed following an accident near Irene, South Dakota. The flight was being operated under 14 CFR Part 91 for personal use. The pilot was flying from Joe Foss Field Airport (FSD) in Sioux Falls to Chan Gurney Municipal Airport (YKN) in Yankton for maintenance purposes. No flight plan had been filed, and the pilot was not in communication with air traffic control.
At the time of the accident, weather conditions at the destination airport consisted of fog with a visibility of 1/4 statute mile and ceilings of 200 feet broken and 1,900 feet overcast. ADS-B data indicates the aircraft departed Sioux Falls at 0701, maintaining a mean altitude of 3,700 feet MSL on a southwest heading. At 0718, the aircraft began a descent. The final recorded data at 0720:52 showed the aircraft performing a descending left turn to the south, followed by a descending right turn.
The aircraft came to rest in an agricultural field facing south. A post-impact fire occurred, consuming the cockpit and much of the forward fuselage. The wreckage was located approximately 100 feet west of a gravel road. The right wing had separated from the fuselage, and a portion of the outboard right wing showed damage consistent with a tree strike.
The investigation
Examination of the engine revealed no anomalies that would have prevented normal operation. The propeller showed damage, including chordwise scaring and S-shape bending, which is consistent with the engine producing power at the time of impact.
Investigators established flight control continuity, noting that all cables remained attached to their respective surfaces, with the exception of a single break in the aileron drive control cable. This break, located approximately 3 inches from its attachment near the control column, was consistent with overload damage.
