The NTSB's narrative final · quoted from the NTSB record

The certified flight instructor (CFI) and a student pilot were performing touch-and-go and full stop landings. The CFI reported that during the final landing roll at 30 miles per hour, the wing rolled severely to the left, and struck the ground. The wing crumpled, and dug into the surface rolling the airplane onto its left side. Postaccident examination revealed that the right rear mast support cable fractured about 3 inches above its lower attachment point where the cable enters a swedge. A Federal Aviation Administration inspector examined the wreckage and confirmed the break to the cable and also noted that there appeared to be some bluish green corrosion on the copper compression swedge.
