The aircraft was proceeding onto Stand 409 at London Heathrow Airport with the Aircraft Parking Information System (APIS) providing correct lateral guidance. The distance indication to the

stopping point did not function and the aircraft passed 11 metres beyond its correct stopping point. A baggage container was incorrectly parked and was protruding into the stand area. The

outboard cowling of the left outer engine contacted the container which caused superficial damage. The APIS had not been activated but due to a wiring defect, the lateral guidance was

illuminated which it should not have been.
