Probable cause

The dual student's inadequate aircraft control resulting in a hard landing. Contributing factors include, the dual student's inadequate airspeed and high flare, the inadequate supervision by the instructor, the in-flight separation of the right main landing gear and the intentional wheels-up landing.

Analysis

According to the instructor, the pilot receiving instruction made a hard landing. The instructor took the controls and initiated a go-around. Suspecting landing gear damage, he kept the landing gear extended and diverted to a nearby airport. On the approach, the right main landing gear fell off the aircraft. Because of the limited emergency equipment at the second airport, he was advised to divert to a third airport. While keeping the landing gear extended, they made a low pass over the runway, and witnesses confirmed the missing right main landing gear. The instructor retracted the landing gear and made an intentional gear-up landing. The airplane sustained extensive damage to the lower fuselage skin and bulkheads and substantial damage to the right main landing gear attachment point.
