Beschrijving:
Flight 940 took off from Mexico City (MEX) at 08:40 for a flight to Puerto Vallarta (PVR), Mazatlán (MZT) and Los Angeles (LAX). The left main gear brake was overheated during the takeoff run. When the aircraft had reached FL310 the heat caused a tyre on the left hand main gear to explode. Fuel and hydraulic lines were ruptured and electrical cables severed resulting in a cabin decompression. An emergency was declared, but spilt fuel ignited and caused a massive fire on board. Control was lost and the aircraft crashed into a mountain in the Sierra Madre, at an elevation of 9000 feet. It was found that the tire had been serviced with air rather than nitrogen. The air, under high temperature and pressure, resulted in a chemical reaction with the tire itself. This led to a chemical explosion of the tire.
