It was a conventional, low-wing monoplane with wide-track fixed tailwheel undercarriage. In service, the aircraft demonstrated a number of serious and fundamental design flaws that led to a series of accidents and pilots joking that Tu-Sa stood for Todo Un Sarcófago Aéreo ("Altogether an aerial coffin"). When it became apparent that the defects could not be corrected without a complete redesign of the aircraft, they were withdrawn from use.{{Citation needed|date=May 2020}}
