On May 20, 2005, about 1640 Pacific daylight time, a Piper PA-28-181, N8460N, taxied into a building following an uneventful landing at the Oxnard Airport, Oxnard, California. Air Desert Pacific Corporation, La Verne, California, operated the airplane under the provisions of 14 CFR Part 91. The airplane was substantially damaged. The private pilot, the sole occupant, was not injured during the personal flight. Visual meteorological conditions prevailed and no flight plan had been filed. The flight originated from La Verne about 1530. The pilot indicated to the National Transportation Safety Board investigator that after landing he requested and received an air traffic control clearance to taxi to the transient parking area. The pilot reported that while taxiing he commenced a right turn and attempted to proceed between parked airplanes and a building. While looking to the right at a nearby parked airplane, his airplane's left wing impacted the building. The pilot was certificated as a private pilot on May 3, 2005.
