On October 11, 2021, at 0857 mountain daylight time, a Beech 58TC airplane, N6748V, was destroyed when it was involved in an accident near Mesa, Colorado. The pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

Fixed Base Operator (FBO) employees at Blake Field Airport (AJZ), Delta, Colorado, stated that before departure the pilot fueled the airplane with 100 gallons of aviation gasoline. The airplane taxied away from the fuel pump at 0839 and proceeded to runway 03. The airplane departed about 0843 and proceeded northeast toward its destination, Southwest Wyoming Regional Airport (RKS), Rock Springs, Wyoming. They also stated that this was the airplane’s first flight after an annual inspection had been completed on October 1, 2021.

Automatic Dependent Surveillance-Broadcast (ADS-B) data revealed that about 0846 the airplane departed from runway 03 and proceeded northeast for about 4 nautical miles (nm), then turned left to north-northwest and climbed over Grand Mesa. After crossing over Grand Mesa, the airplane reached about 14,000 ft mean sea level (msl). At 0855:51 the airplane turned right and descended about 1,000 ft, then climbed to 15,000 ft. At 0856:26 the airplane descended rapidly toward terrain.

A summary of air traffic control (ATC) communications revealed that pilot was in contact with ATC and at 0852 he reported climbing through 11,000 ft for 14,000 ft. At 0857:00 the controller asked the pilot, “did you get an updraft, mountain wave out there? I’m showing you 800 ft high.” There were no other communications from the pilot.

A review of the meteorological information revealed the potential for light to moderate turbulence and mountain wave activity near the accident site. National Weather Service had no active AIRMET, SIGMET, Convective SIGMET, or Center Weather Advisory, for the route of flight.

The airplane impacted a rocky mountainside and remained upright on a heading of about 040°. The wreckage debris path was about 30 ft long and mostly consisted of paint chips, shards of windscreen, various small debris and a large outboard section of the right wing that had separated on impact. The empennage was distorted to the left and remained partially attached to the rear fuselage. The bottom of the airplane exhibited impact damage and scoring from the rocky terrain. The left engine was mostly separated from the left wing nacelle, while the right engine remained attached to the right wing nacelle. The six propeller blades were relatively undamaged and did not exhibit leading edge damage or scoring.

The airplane has been retained for further examination.
