After that trip they decided to continue towards Mexico City making a stop in Havana, however the plane disappeared near Villahermosa, Tabasco and after numerous searches among which the Mexican pilot Francisco Sarabia Tinoco participated with his airline "Transportes Aéreos de Chiapas", however the remains were not found.

[1] Francisco Sarabia wanted to return the gesture to the Spanish pilots making a nonstop flight between Mexico and Spain in a nationally manufactured aircraft, for which he had the support of the Mexican government and TNCA.

[5] The aircraft began to be built in October 1933 at the Talleres Nacionales de Construcciones Aeronáuticas (TNCA, National Aeronautical Construction Workshops) in Mexico City and it was completed in June 1934 with the registration XA-EXS, beginning on that month the tests on land where the landing gear was damaged.

[6][7] The plans for the Mexico-Spain flight were delayed because Francisco Sarabia claimed that he plane tended to get stuck, leaned heavily to the left and it was difficult to keep it stable, while the Russian engineer complained about the lack of experience and expertise of the Mexican pilot.

The airplane was kept secret for a long time, until it was dismantled in the TNCAs and its engine was used to be the powerplant of a Corsario Azcárate.
