What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On July 24, 2026, a Waco Aso, registration privacy data omitted, departed khao (Butler county regional airport) for a local flight with one pilot and three passengers on board. VFR weather conditions prevailed at the time, with winds reported as variable at 3 knots and 10 miles visibility.
At approximately 11:40 eastern time, the aircraft conducted a landing on runway 30 with a pilot-reported touchdown speed of 40 mph. At touchdown, the airplane veered to the right, despite the pilot applying "corrective control inputs." The left lower wing tip struck the runway surface and drug for approximately 30 feet. Post-accident examination revealed abrasion wear to the lower outboard wing consistent with a wing tip strike and aprroximatley 30 feet of rubber transfer marks consistent with side loading of the left main gear tire. Shortly after, the left main wheel completely detached from the airframe. Post accident examination revealed damage to the left lower inboard section of the lower wing, piercing of the fabric and a fracture of at least one structural rib. This was followed shortly after by the complete detachment of the right main wheel. Further post-accident examination revealed tire rubber transfer marks on the right lower inboard wing as well as on the upper portion of the right main landing gear oleo strut.
The aircraft slid on the MLG v-struts and came to a rest on the right edge of runway 30, oriented on a heading of approximately 032 degrees, with the nose of the airplane extending over the runway edge with the MLG v-struts resting in the grass just off the runway edge. Post-accident examination of the propeller revealed one blade exhibited tip curling consistent with soft terrain contact, with grass and soil embedded between the wooden tip and the brass protective sheath. There was no evidence of a post-crash fire.
There were no injuries reported among the four occupants and the aircraft's ELT did not activate during the sequence.
