Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that following a local flight, on final approach to land, about ¼ mile from the runway, he glanced down at the airspeed indicator, and then glanced up and “all of a sudden” a flock of birds flew into the airplane. He stated it was “like a wall” or like a “machine gun” going off in his flight path. He reported that the birds collided with the airplane and after that point he “was a passenger”. He recalled the airplane entered an aerodynamic stall and spin and subsequently descended and impacted trees and terrain. The fuselage and wings sustained substantial damage. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane.
