## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

AIRCRAFT N930WN WAS PARKED AT GATE B22 AT MIDWAY (MDW) AIRPORT AND ACTIVELY LOADING PASSENGERS WHEN IT WAS STRUCK BY A BAGGAGE CART TUG. THE AREA ON THE AIRCRAFT THAT WAS STRUCK WAS ON THE LEFT SIDE OF THE FUSELAGE, FORWARD OF THE #1 ENGINE. THE AIRCRAFT SUSTAINED SUBSTANTIAL DAMAGE TO THE LEFT SIDE AND THE UNDERBELLY. THE BAGGAGE CART TUG DRIVER STATED THAT THE TUG WENT TO FULL RPM AND HE WAS UNABLE TO STOP THE TUG. THE TUG DRIVER USED THE TUG BRAKES AND THE EMERGENCY BRAKES. HE ALSO DROVE INTO EMPTY BAGGAGE CARTS TRYING TO USE THEM TO STOP THE TUG.  WHEN THIS DID NOT WORK HE JUMPED OFF THE TUG AND THE TUG VEERED TOWARDS AND STRUCK THE AIRCRAFT.

AFTER THE ACCIDENT, THE AIRCRAFT WAS TOWED TO A SOUTHWEST HANGAR AT MDW. A BOEING TEAM ARRIVED TO ASSESS THE DAMAGE AND CREATE A COST ESTIMATE FOR REPAIR. THE BOEING ENGINEERS STATED THAT THE DAMAGE WAS CONSIDERED SUBSTANTIAL.  THE DAMAGE WAS AT SECTION 43, FROM B STA 360 TO 540, STRINGER 13L TO STRINGER 26R. SKIN PANELS, STRINGERS, AND FRAMES WERE REPLACED IN THIS AREA. SOUTHWEST PROCEEDED WITH THE REPAIR AND IT WAS COMPLETED ON 11/08/2017.
