Probable cause

The disconnection of baggage carts that subsequently collided with the parked airplane following the tug driving over a dip in the roadway.

NTSB narrative

The commercial air carrier airplane was parked at the boarding gate with the crew onboard. A tug driver from another airline was pulling four baggage carts in the non-movement area adjacent to the boarding gates. A security video showed that the second cart hit a drain cover and detached from the preceding cart. The loose baggage carts then rolled across the ramp and into the side of the airplane, resulting in substantial damage. There were no injuries.
