Beech 33 accident near Granbury, Texas, February 8, 2020

On February 8, 2020 at about 7:17 pm local time, a 1979 Beech 33, registered N6665U, was substantially damaged in an accident during approach (VFR pattern base) near Granbury, Texas (Granbury Rgnl airport). It was a personal flight under general aviation rules (Part 91). 1 person was killed. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The pilot's exceedance of the airplane's critical angle of attack while maneuvering in the airport traffic pattern, which resulted in an aerodynamic stall and loss of control.

The NTSB's narrative final · quoted from the NTSB record

The pilot was conducting a personal flight to a nearby airport. Flight tracking information and a statement from another pilot indicated that the pilot overflew the runway, entered the airport traffic pattern, landed, and taxied the airplane off the runway. About 7 minutes later, the airplane was captured on radar as it flew downwind in the traffic pattern and proceeded north. About 2 minutes later, the radar data ended; the accident site was located 0.39 nautical mile north-northeast of the final radar return. The airplane impacted trees and terrain in a nose-low attitude with minimal forward momentum and a slightly twisted empennage, consistent with an aerodynamic stall/spin. Examination of the airplane did not reveal any mechanical malfunctions or anomalies that would have precluded normal operation. It is likely that the pilot was flying an extended pattern and turning from the base to final legs of the pattern when he exceeded the airplane's critical angle of attack, which resulted in an aerodynamic stall, loss of control, and impact with terrain.
