## Preliminary report

On November 10, 2025, about 1815 mountain standard time, a Piper PA-28-235 airplane, N9143W, was substantially damaged when it was involved in an accident near Castle Rock, Colorado. The pilot and one passenger reported no injuries. A second passenger reported minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot reported that, while in cruise flight, he observed a slight decrease in engine speed. He immediately applied carburetor heat. However, about two minutes later, the engine lost all power.

No one in the car was injured. An engine examination is planned following recovery of the airplane.
