On December 21, 2020, at 1525 Pacific standard time, a Navion A, N4106K, was substantially damaged when it was involved in an accident near Livermore Municipal Airport (LVK), Livermore, California. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight. The pilot was conducting a test flight and reported the runup was normal and the engine developed full power during takeoff. However, shortly after takeoff, as he turned crosswind and throttled back, the engine started to miss, and the airplane wouldn’t climb. The pilot returned to runway 25L for landing.
