Summary
On March 10, 2008, a Piper PA-22 (N1424A) was involved in an incident near Nickerson, KS. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's failure to maintain directional control during the landing roll resulting in a departure from the runway environment. Contributing to the accident was the soft runway surface.
According to the accident report form submitted by the pilot, during the landing roll to a private dirt strip, the airplane began to veer off the left side of the runway. The pilot attempted to correct with right rudder; however, the airplane continued to the left. The airplane departed the landing environment and nosed over. The leading edge of both wings was crushed aft, the fabric wrinkled, several ribs were broken, and the firewall was wrinkled. The top portion of the rudder was crushed down. The pilot observed tracks on the ground "where the left tire was dragging like it had locked up." The pilot stated that the airplane does not have differential brakes. In addition, he reported that the master cylinder for the brake system is located a few inches above the exhaust muffler.
This incident is documented in NTSB report DEN08CA063. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N1424A.

Analysis
According to the accident report form submitted by the pilot, during the landing roll to a private dirt strip, the airplane began to veer off the left side of the runway. The pilot attempted to correct with right rudder; however, the airplane continued to the left. The airplane departed the landing environment and nosed over. The leading edge of both wings was crushed aft, the fabric wrinkled, several ribs were broken, and the firewall was wrinkled. The top portion of the rudder was crushed down. The pilot observed tracks on the ground "where the left tire was dragging like it had locked up." The pilot stated that the airplane does not have differential brakes. In addition, he reported that the master cylinder for the brake system is located a few inches above the exhaust muffler. He reported that when the cylinder is hot, it will result in the brakes dragging.
An airworthiness inspector with the Federal Aviation Administration conducted an examination of the airplane systems, to include the flight controls, wheels and brakes. An examination of these systems revealed no anomalies. The inspector reported that the runway surface and shoulder were "very soft." Pictures of the runway environment revealed ruts from previous takeoffs and landings and the accident flight. The inspector reported that the ruts from the accident flight revealed the airplane touched down left of the centerline on the runway.
