An aircraft on an IFR flight at 7,000 ft reported a spin before crashing into wooded terrain near a mountain ridge. The horizontal stabilizers separated in flight due to overload.

Incident Overview and Witness Account An aircraft was operating under instrument flight rules (IFR) at an altitude of 7,000 feet when the pilot reported, “SIX TWO ZERO SIX PAPA SPINNING” at 1158:29. The aircraft subsequently crashed into wooded terrain near the top of a mountain ridge. A witness who observed the aircraft before the crash described unusual cloud formations and strong, gusty winds in the area. The witness stated that the aircraft disappeared behind a wall of clouds and reappeared, entering a spin before climbing back up almost as quickly as it had descended, prior to the crash. ## Wreckage Examination and Weather Data An examination of the wreckage revealed evidence that the horizontal stabilizers separated in flight. The stabilizers were found away from the main wreckage and had failed in a downward direction from overload. No other preimpact part failure was evident. Weather radar data indicated that the aircraft had crashed in the area of a level 2 echo.
