On January 17, 2005, about 1240 eastern standard time, a Boeing 737-247, N373DL, was substantially damaged when it was struck by a catering truck, while parked at the Cincinnati-Northern Kentucky International Airport (CVG), Covington, Kentucky. The 2 airline transport certificated flight crewmembers, 2 flight attendants, and 10 passengers were not injured. Visual meteorological conditions prevailed and an instrument flight rules flight plan was filed for the scheduled flight operated by Delta Airlines, as fight 583. The flight was conducted under 14 CFR Part 121. According to a representative from Delta Airlines, the airplane was parked at gate B18, and was in the process of boarding passengers, when it was struck on it's right side by a catering truck. Damage to the fuselage included a 6-inch, by 14-inch puncture, and several small dents. In addition, two formers and one stringer were damaged.
