May 25/13-The Win Win Aviation Beechcraft B90 aircraft (N32BA) was operating under a Canadian Foreign Air Operator Certificate (Foreign Trade Agreement) for Skydive Gananoque. The sole occupant, a Canadian commercially licensed pilot, was performing circuits to become more familiar with the aircraft. As the aircraft was touching down on runway 36, the landing gear had not been extended. The aircraft contacted the runway with the underside of its fuselage and slid off the paved runway and on to the grass infield where it came to stop. The pilot was not injured but the aircraft was substantially damaged.
