On 23 September 2017, a large wing-to-body fairing panel confirmed to have dropped from a Boeing 777-200 passing over the centre of Osaka after takeoff off from Kansai hit and significantly damaged a moving vehicle. The Investigation found that the panel involved had a sufficient history of attachment bracket failures for Boeing to have developed an improved thicker bracket for new-build aircraft which had then been advised as available as a replacement for in-service 777-200 aircraft in a Service Letter which KLM had decided not to follow. Although some incorrect bracket attachment bolts were found, this was not considered contributory.
