In December 2017, an Air Canada passenger experienced a terrifying moment when a screw from the plane's propeller came loose mid-flight and smashed into the window by his seat. The passenger shared images on Reddit of the alarming incident, which occurred on a flight to Vancouver.
He described hearing a loud "pop" and then noticing that a screw had embedded itself in the outer pane of the window. The noise caused concern among passengers, and the flight attendant promptly notified the pilot. The pilot, who had over 25 years of flying experience, stated that he had never encountered such an incident before.
Upon landing, the pilot spoke with the “lucky” passenger at length, revealing that even the aircraft manufacturer, Bombardier, had never seen a case of a screw coming loose and embedding itself in a window.
An Air Canada spokesperson confirmed the incident, stating that one of the twelve one-inch bolts on the "prop spinner" had come loose during the descent into Vancouver. The bolt struck the exterior pane of the two acrylic window panes, resulting in a small hole. Fortunately, the interior pane was not impacted, and the aircraft landed safely without further incident.
Events like these highlight the critical importance of proper maintenance and the use of high-quality fasteners in the aviation industry.
