Analysis
Before flt the pilot had stated that his uncertified and unregisterd gyroplane had a 'lot of bugs to work out'. After t.o. and five min of airwork the acft entered a steep 90 degree banked turn and then began to tumble. Shortly after the main rotor separated. No record could be found of training in this type aircraft.
