Investigator assessment
Analysis narrative
The pilot of the personal flight reported that he was enroute to his destination airport when he began a 500 fpm rate descent to 3,000 ft msl. While descending through 4,100 ft msl, a bald eagle, that was above the airplane’s flight path descended at about a 40o angle and struck the airplane’s left wing. The airplane continued to without any appreciable change to its performance and the pilot continued to the destination airport. For the approach, the pilot extended the landing gear, extended the wing flaps to 10o, and slowed the airplane to 105-110 kts for level flight at 3,000 ft msl. On final approach, the pilot flew the airplane at 85-90 kts and landed uneventfully with 30o of wing flaps. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
