On September 17, 2021, about 0800 central daylight time (CDT), a Boeing A75 airplane, N19BB, was destroyed when it was involved in an accident near Delta, Colorado. The commercial pilot sustained fatal injuries. The personal local flight was conducted under the provisions of Title 14 Federal Code of Regulations Part 91.
The airplane took off from runway 3 at Blake Field Airport (AJZ), Delta, Colorado. Two witnesses observed the airplane climb out and begin aerobatic maneuvers about 5 miles to the northeast of AJZ. Both witnesses stated that the airplane began a loop maneuver, and at the top of the loop while inverted, the airplane entered a flat spin. They observed the airplane recover from that spin. The airplane then gained altitude and they observed the airplane begin another loop maneuver. At the top of the loop, while inverted, the airplane entered another flat spin and did not recover. The airplane impacted rugged sloped terrain about 5 miles to the northeast of AJZ. First responders located the airplane wreckage and notified authorities. There were no radio or distress calls heard from the pilot.
The wreckage was found resting inverted on a 45-degree slope. The fuselage was oriented downslope and crushed from impact forces. The engine was partially separated from its fuselage mounts. The empennage section was bent rearward, the upper wings were bent upward, and lower wings were separated from their respective mounting braces, consistent with a flat impact. Flight control continuity was confirmed from the cockpit to all flight control surfaces. The engine throttle control was found in the idle position. Engine rotation continuity (compression resistance) was confirmed. The smell of fuel was present. The airplane was not equipped with inverted fuel or oil supply systems.
According to an acquaintance of the pilot, he and the pilot flew the airplane to AJZ a few days prior to the accident flight. The acquaintance stated that the airplane operated normally.
