On June 19, 2002, about 1635 eastern daylight time, a Cessna 152, N95035, was substantially damaged while taxing at the Allegheny County Airport (AGC), Pittsburgh, Pennsylvania. The certificated student pilot was not injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the local solo instructional flight conducted under 14 CFR Part 91. According to a written statement from the student pilot, the airplane had just landed, and he was taxing to the parking area. The student pilot stated that while approaching the parking area on the taxiway, he saw a person walking, and veered to the left of the yellow taxi line. The student pilot thought he had adequate clearance between the airplane's left wing and a parked fuel truck; however, the left wing struck the fuel truck and sustained damage. An examination of the airplane by a Federal Aviation Administration (FAA) inspector, revealed damage to the leading edge of the left wing. Upon further examination of the wing, damage to the rear wing spar was observed. The student pilot did not report any mechanical problems with the airplane.
