What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
This flight was the first flight for this aircraft. Pilotprivacy data omitted attemped departure twice before actual takeoff. In each of the prior attempts, the rotor would not pre-rotate. This problem was fixed by ajusting a micro-switch in aft seat. Aircraft departed runway 27 for a left traffic pattern. Upon takeoff pilot noted "tight control feel." As the aircraft climbed the pilot needed full left stick to maintain level flight. He executed left turns with rudder. Upon landing, the aircraft landed with only right main wheel on runway. The pilot was unable to lower left side and the aircraft rolled to the right off the runway and sustained substantial damage. Investigation continues. The control mixing unit under pilot seat will be inspected.
