A fifteenth victim of the Lear jet crash in Mexico has died. The 44-year-old woman died Tuesday; she had been hospitalized since the crash on November 4th.
The NTSB has concluded that wake turbulence was the problem that downed the jet. Air traffic controllers told the Learjet pilots to slow down significantly so as to not gain ground on the 767, but they flew into wake 4 miles behind the jet. This action has been interpreted as pilot error. Additionally, the contract pilots may not have been qualified on the jet as deficiencies in their certifications were uncovered.
The Learjet departed San Luis Potosà (SLP) at 18:04 on a flight to Mexico City (MEX). On board were a.o. Mexican Interior Minister Juan Camilo Mourino, Deputy Attorney General Josi Luis Santiago Vasconcelos and Miguel Monterubio Cubas, the director of social communication.
The flight was uneventful and the Learjet passed LUCIA VOR at 18:40 and ATIZAPAN VOR at 18:42. It passed SAN MATEO VOR at 18:44, at an altitude of 11000 feet and an airspeed of 262 kts. It was trailing a Boeing 767-300 (Mexicana Flight 1692 from Buenos Aires). At 18:45 hours the aircraft was instructed to switch to the Tower frequency which the pilot acknowledged but never contacter Mexico Tower. At 18:46 the flight was observed approaching runway 05L. The last radar position of the aircraft was 7.5 miles from the Mexico VOR on the 256 radial, at an altitude of 9700 feet at 185 kts airspeed.
The airplane crashed on the Avenida Reforma and caught fire. Several cars were destroyed and at least five people on the ground were killed.
