BRM Costruções Aeronáuticas

BRM Costruções Aeronáuticas (BRM Aircraft Manufacturing) is a Portuguese aircraft manufacturer based in Pêro Pinheiro, Sintra. The company specializes in the design and manufacture of ultralight aircraft in the form kits for amateur construction and ready-to-fly aircraft for the European Fédération Aéronautique Internationale microlight category.

The company is noted as one of very few light aircraft manufacturers located in Portugal, a country not known for aircraft production.

BRM's aircraft are built with aluminium sheet "all-metal" construction. The company's first light two-seat STOL design was the BRM Okavango, which was superseded by the BRM Land Africa. The BRM Citius is an improved model, with a higher cruise speed. The company also produces a low-wing design, the two-seat BRM Argos.

Chris Heintz, the designer of the Zenith STOL CH 701 considers the Land Africa an unauthorized copy of the CH 701.
