The TNCA B Series was a single-engine reconnaissance biplane built in Mexico by Talleres Nacionales de Construcciones Aeronáuticas (National Aircraft Construction Workshops).

Under his direction, an airplane was built based on the structure of the TNCA Serie A, to which major modifications were made, such as larger dimensions and the adaptation of a Salmson 9-cylinder radial engine, the prototype received the registration 1-B-72.

[1] After successful demonstrations of this aircraft, the government authorized the construction of five more examples, which were affectionately dubbed "puros" (cigars), due to their wide tubular fuselages, which was the main difference compared to the TNCA Serie A.

The six aircraft were operated by the Mexican Air Force from their base at Mexicali, in anti-smuggling flights.
