Colorado Aviation Accidents & Incidents

HISTORY OF FLIGHTOn May 3, 2020, at 1110 mountain daylight time, a Rans S-12 airplane, N427LB, was destroyed when it was involved in an accident near Delta, Colorado. The pilot sustained fatal injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 test flight.

A witness stated that he talked to the pilot about the airplane’s stability issues, and the pilot told him that he performed some high-speed taxi tests and was trying to adjust to correct the issues. The witness did not think the pilot was going to fly [on the day of the accident] and was only going to perform another set of high-speed taxi tests. The witness believed the pilot was caught off guard and the airplane became airborne.

A witness at Blake Field Airport (AJZ), Delta, Colorado, stated that he saw the airplane takeoff from runway 14, and it appeared to be under control.

The airplane flew along the left downwind leg for runway 21 about 300-400 ft above ground level, in straight, level, and stable flight. After the airplane passed the approach end of runway 32, it pitched down, banked sharply right, and the engine throttled back. The witness said it was hard to tell if the engine was throttled back before the sudden change in pitch or in its response to the change in pitch; a loss of control/stall occurred.

Another witness at AJZ stated that he heard an engine repetitively going from full engine power, then back off, and then return to full engine power. He said that when he saw the airplane, he thought the wings were rocking. The airplane banked to the right, was very low, and pitched "a lot." About 3–4 seconds later, the airplane impacted the ground.
