Aircraft involved
Probable cause & findings
A failure of the pilot to maintain adequate distance/clearance from a cement barricade while taxiing into a parking spot after landing. A factor was the presence of a barricade adjacent to the parking spot.
Factual narrative
On April 19, 2001, about 1600 Alaska daylight time, a wheel/ski equipped deHavilland DHC-2 airplane, N4793C, sustained substantial damage while taxiing from landing at the Lake Hood Strip, Anchorage, Alaska. The airplane was being operated as a visual flight rules (VFR) local area government flight under Title 14, CFR Part 91, when the accident occurred. The airplane was operated by the Civil Air Patrol, Inc., Elmendorf Air Force Base, Anchorage. The commercial certificated pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The flight originated at Merrill Field, Anchorage, about 1530. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on April 20, 2001, the pilot reported he was taxiing to a parking spot at the Civil Air Patrol maintenance hangar. He maneuvered the airplane toward the parking spot that was bordered by cement barriers. During a turning maneuver, he swung the tail of the airplane to the right, and the outboard end of the right elevator struck one of the barriers. At the completion of a local flight, the commercial certificated pilot was taxiing to a parking spot at a maintenance hangar. He maneuvered the airplane toward the parking spot that was bordered by cement barriers. During a turning maneuver, he swung the tail of the airplane to the right, and the outboard end of the right elevator struck one of the barriers.
