On January 11, 2004, about 1000 Pacific standard time, a Cessna 152, N67844, collided with a fuel truck while taxing to parking at Montgomery Field (MYF), San Diego, California. The airplane, registered to and owned by a private individual, was being operated under the provisions of 14 CFR Part 91. The private pilot, the sole occupant, was not injured; the airplane sustained substantial damage. The personal local flight departed MYF about 0915. Day visual meteorological conditions prevailed, and a flight plan had not been filed. In a written statement, the pilot reported that she had completed several touch-and-go practice takeoff and landings and was taxiing back to the tie down area. While taxiing on the ramp area, between rows of parked airplanes, she noticed a parked fuel truck ahead of her on the left side. After deciding she had adequate clearance between the airplane and the fuel truck, she continued taxiing and momentarily glanced down at the airplane's checklist. She stated that she "incorrectly judged" the distance between the airplane and fuel truck, and the airplane struck the fuel truck with the outboard section of the left wing. The airplane incurred substantial damage to the left wing. The pilot reported no preimpact mechanical malfunctions or failures with the airplane.
