N319UA

According to the pilot, the purpose of the flight was to practice takeoff and landing at night, and due to the obstructions below, the pilot flew the approaches at a “steep” angle. He had successfully completed about nine uneventful approaches and landings before the accident approach. During the accident approach the pilot noted some light turbulence and the airplane began to descend below the “normal” glide path. He added power and arrested the descent, but the airplane struck some trees. He noted that the airspeed or the pitch of the airplane did not change when the airplane struck trees. He made an uneventful landing, but during the post-flight inspection noticed substantial damage to the leading edges of the wings and horizontal stabilizer. The pilot did not report any mechanical anomalies with the airplane. The winds reported at the airport about the time of the accident were calm.
