History
The plane, nicknamed "Veracruz", was piloted by Captain Carlos Guadarrama Sixto, an experienced Mexicana captain with 15,000 hours of flying experience. The crew of seven included five flight attendants, one of whom was the wife of the captain. 159 passengers were on board. At 8:50 in the morning, the plane took off from Benito Juárez International Airport en route to Los Angeles International Airport with stopovers in Puerto Vallarta and Mazatlán.
Crash
At 9:05 in the morning, an explosion shattered the fuselage. Captain Guadarrama and the crew in the cockpit, realizing that the plane was shaking too much, declared an emergency to the air traffic controller and asked to return to Benito Juárez International Airport for an emergency landing. The airport was prepared for the landing, but before reaching its destination the plane broke in two, burst into flames and crashed on El Carbón mountain near the town of Maravatío, Michoacán. Eyewitnesses reported details of the crash to authorities. All 167 passengers and crew were killed instantly. After the crash, some townspeople stole items that belonged to the victims. The local police and the Mexican army were called and the crash site was closed to unauthorized people so that investigations could begin.
Investigation and aftermath
The crash occurred in the Sierra Madre Oriental mountain range
Initially, two Middle Eastern terrorist groups claimed responsibility for the crash. An anonymous letter signed by those groups claimed that a suicide mission had sabotaged the plane in retaliation against the United States.[3][4]. However, sabotage was later dismissed as a cause of the crash. The investigations were carried out by the NTSB and Mexican aeronautical authorities, who found that the cause of the accident was due to the center landing gear tire being filled with compressed air, instead of nitrogen. In addition, the tire had some marks of overheating. The investigators later found that the overheating was caused by a malfunctioning brake on the landing gear. [5]
Mexicana maintenance personnel were blamed for negligence in maintaining the 727 and for filling the tire with regular compressed air, instead of nitrogen. The crash remains the deadliest airline disaster in Mexican history[6] and is the world's worst air disaster involving the Boeing 727. The cause of the in-flight fire remains unknown.
