CEN20TA088

The pilot reported that with about 500 ft of the 2,200-ft runway remaining, the airplane was traveling about 60 mph; the liftoff speed is 60 to 65 mph. He considered aborting the takeoff but determined that it was not safe due to the road that ran perpendicular to the end of the runway. As the pilot rotated the airplane, it abruptly pitched up, began sinking, and did not accelerate, so he elected to land straight ahead in an open field. After touchdown, the right landing gear broke and the spring leg dug into the ground. The airplane subsequently rotated about the leg, and the fuselage sustained substantial damage. The pilot had conducted a preflight inspection of the airplane and determined the weight and balance of the airplane was within the manufacturer's limits. He estimated that the takeoff ground run distance was about 1,400 ft, which was about 70% more than the owner's manual recommended. Thus, it is likely that, although sufficient runway was available for takeoff, the airplane did not accelerate sufficiently to sustain flight. Further, the pilot failed to recognize that the airplane wasn’t accelerating and did not abort the takeoff when the airplane passed the point where he had anticipated the liftoff would occur.

On February 16, 2020, about 1502 central standard time, a Cessna 170 airplane, N170RH, impacted terrain during takeoff from runway 17 at the High Point Airport (3KS5), near Valley Center, Kansas. The airline transport pilot sustained minor injuries and the three passengers were uninjured. The fuselage was substantially damaged during the impact. The airplane was registered to and operated by a private individual as a Title 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed in the area about the time of the accident, and the flight was not operated on a flight plan. The local flight was originating from 3KS5 at the time of the accident. The pilot reported that he was taking off when the accident occurred. He conducted a preflight inspection of the airplane, and also determined the weight and balance of the airplane was within the airframe manufacturer's limits. He estimated that the takeoff ground run distance was about 1,400 ft, which was about 70% more than the owner's manual performance value for a normal takeoff with no wind using a level, paved runway. He walked some of the takeoff area and determined the grass runway was "wet, but a solid surface." The windsock indicated about 8 knots at 160°. With over 2,200 ft of runway available and a slight downhill gradient, he deemed the available runway length to be adequate. He held the brakes letting the airplane reach maximum power before he released the brakes. The pilot reported that the aircraft was indicating 60+ mph with about 500 feet of runway left when he considered aborting the takeoff, but determined that was not safe due to the road that ran perpendicular to the end of the runway. He continued to accelerate and rotated at the end of the runway. The aircraft abruptly pitched up and the pilot lowered the nose. The aircraft began sinking and was not accelerating. the pilot determined the best course of action would be to land straight ahead in an open field. After touchdown the aircraft's right side spring landing gear broke and the spring leg dug into the ground. The airplane subsequently rotated, and the fuselage sustained substantial damage. The pilot indicated that there were no mechanical malfunctions with the airplane during the takeoff, and that the airplane had accelerated normally.
