On October 29, 2002, about 1600 Alaska standard time, a wheel-equipped Cessna 180 airplane, N5355D, sustained substantial damage when it struck trees while landing at a remote off airport site, located about 5 miles southeast of Larson Bay, Alaska. The airplane was being operated as a visual flight rules (VFR) personal flight under Title 14, CFR Part 91, when the accident occurred. The commercial pilot, and the one passenger, were not injured. Visual meteorological conditions prevailed, and a VFR flight plan was filed. The flight originated about 1450, from the Homer Airport, Homer, Alaska. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge on November 7, the pilot reported that the off airport site he was landing at required an approach over a stand of trees near the beginning of the site. He said that during the final approach phase of the landing, the left wing struck a previously unnoticed tree branch, and the airplane veered to the left of the intended touchdown point. He said that he attempted to correct to the right, but the airplane touched down to the left of the landing site and collided with trees. The airplane sustained substantial damage to both wings, fuselage, and empennage. The pilot reported that there were no preaccident mechanical anomalies with the airplane. The pilot did not submit an NTSB Pilot/Operator Aircraft Accident Report (NTSB Form 6120. 1).
