On March 31, 1986, Flight 940 crashed in Las Mesas; near Maravatio, Michoacan. All 167 people on board the Boeing 727-264 were killed, making it the deadliest plane crash in the country's history and the deadliest ever to have involved this type of aircraft. The left main gear brake was overheated during the take-off run. After reaching an altitude of 31,000 feet, a tire in the left main landing gear burst and crippled the plane's controls, causing an in-flight fire and an explosive decompression in the process. It was found that the tire had been filled with air rather than nitrogen, leading to a chemical explosion within the tire itself.
