LAX06LA154

The airliner was struck by a loose string of baggage carts while taxiing for departure. The airplane was traveling down a taxiway toward the active runway, and upon reaching an intersection, the captain noticed a loose string of baggage carts moving rapidly toward the airplane in an angled path from left to right. He swerved the airplane to the right of the centerline in an effort to avoid collision with the baggage carts. The lead rolling baggage cart struck the airplane's left wing, and the airplane traveled about 150 feet further down the taxiway before coming to a complete stop. The lead baggage cart came to rest wedged between the wing and taxiway surface. The airplane sustained substantial damage. The string of carts came from the direction of the concourse D gates 10 through 14. The baggage carts were equipped with a manual towbar actuated front two-wheel brake system. The parking brake is designed to activate by the operator raising the towbar to the vertical position. To release the parking brake, the brake/towbar-latch is pushed down by foot while the top of the tow bar is pushed inward toward the cart until the brake/towbar-latch is unhooked. Northwest Airlines, the owner of runaway carts, issued an employee memorandum after the accident reiterating the importance of ensuring that the braking system is engaged when leaving carts unattended.

On April 30, 2006, at 2301 Pacific daylight time, a Bombardier CL-600-2D24, N909FJ, operated by Mesa Airlines, Inc., as Air Shuttle flight 6903, was stuck by a baggage cart while taxiing for takeoff at Mc Carran International Airport, Las Vegas, Nevada. The airline transport pilot and first officer, 2 flight attendants, and 85 passengers were not injured. The airplane sustained substantial damage. Visual meteorological conditions prevailed for the 14 CFR Part 121 scheduled domestic passenger flight that was operating on an instrument flight rules (IFR) flight plan. The flight was originating from Las Vegas, with a planned destination of Dallas-Fort Worth International Airport, Dallas, Texas.

According to a representative from Mesa Airlines, Inc., the airplane was traveling east down taxiway "C" toward the beginning of runway 25R. Upon reaching intersection C2, the captain noticed a string of baggage carts moving rapidly toward the airplane in an angled path from left to right. He swerved the airplane about 50 feet to the right of the centerline in an effort to circumvent the collision. The lead cart of the rolling baggage cart string struck the airplane's left wing, and the airplane traveled about 150 feet further down the taxiway before coming to a complete stop. The baggage cart came to rest wedged between the wing and taxiway surface. The airplane incurred damage to the left wing, encompassing the following areas: the slat, leading edge, undercarriage below the aft cargo door, and left wing tip edge.

The baggage cart was equipped with a manual towbar actuated front two-wheel brake system. The parking brake is designed to activate by the operator raising the towbar to the vertical position. When the bar is manipulated to this upward position, the brake/towbar-latch is hooked to a separate bar containing the brake tension-adjusting bolt. To release the parking brake, the brake/towbar-latch is designed to be pushed down by foot while the top of the tow bar is pushed inward toward the cart until the brake/towbar-latch is unhooked.

The string of carts came from the direction of the concourse D, gates 10 through 14. Northwest Airlines, the owner of runaway carts, issued an employee memorandum after the accident reiterating the importance of ensuring that the braking system is engaged when leaving carts unattended.
