Date & Time: 11/19/2018, 1530 MST

Flight Conducted Under: Part 91: General Aviation - Flight Test 

On November 19, 2018, about 1530 mountain standard time, an experimental amateur built BKF Backcountry Super Cub airplane, N59BK, was substantially damaged during a forced landing shortly after takeoff from Casper/Natrona County International airport, Casper, Wyoming. The commercial pilot and pilot-rated passenger were not injured. The airplane was registered to BKF Aviation Ltd, Boston, Massachusetts, and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a test flight. Visual meteorological conditions prevailed at the airport about the time of the accident and no flight plan was filed. The local flight was originating at the time of the accident.

According to the pilot, he initiated takeoff from runway 21, utilizing full power. After the airplane became airborne, he slightly reduced power. As the airplane ascended above 500 ft above ground level, the pilot increased engine power, which was followed by a total loss of engine power shortly after. The pilot initiated a left descending turn and attempted to return to the runway. During the turn, he realized that he would not be able to complete the turn to completely realign with the runway, and leveled the wings, to land on the runway and roll off the runway edge into the grass. The airplane subsequently landed hard on the right side of runway 21, and the left main landing gear axle separated.

Examination of the airplane by a Federal Aviation Administration inspector revealed that the left-wing strut was structurally damaged. The airplane was relocated to a secure facility for further examination.
