On May 25, 1995, about 1415 eastern daylight time, a Cessna A150L, N6188F, registered to a private individual, veered left and separated the right main landing gear during landing at Kendall-Tamiami Executive Airport, Miami, Florida, while on a 14 CFR Part 91 instructional flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the commercial-rated pilot/flight instructor and dual student were not injured. The flight originated from Miami, Florida, on May 25, 1995, about 1330. The flight instructor stated the aircraft had been modified to remove the nose landing gear and install a tail landing gear. The student performed a normal landing and they were rolling down the runway with the tailwheel on the runway, when the aircraft began to veer to the left. He took control of the aircraft and attempted to correct the left veer. The student appeared to have become confused and applied full left rudder and his corrections to the right were unsuccessful. As the aircraft turned further left the right main landing gear separated at the attach point due to the excessive loading. The right wing contacted the runway and the aircraft came to rest. Postaccident examination of the aircraft by FAA inspectors showed no evidence of precrash failure or malfunction of the tailwheel steering system or right main landing gear.
