CBS Heliport

The closure was most likely for administrative or economic reasons. Private rooftop heliports like this one require continuous and costly certification from Brazil's National Civil Aviation Agency (ANAC). The closure likely occurred because the primary corporate tenant who used and maintained the heliport either ceased operations, moved from the building, or no longer found it economically viable to maintain the ANAC certification. There is no evidence of closure due to an accident, military conversion, or environmental issues.

The site is the rooftop of the active commercial office building, Edifício Berrini 500, located at Av. Eng. Luís Carlos Berrini, 500. Satellite imagery shows that the helipad markings (a circle with an 'H') are still visible on the roof. However, the heliport is officially decommissioned and is not legally permitted to handle air traffic. The rooftop is simply part of the building's structure and is not in use for aviation.

CBS Heliport was a private rooftop heliport located atop the Edifício Berrini 500, a major commercial building in São Paulo's business district. Its significance lies in being representative of the city's massive corporate helicopter infrastructure, which is one of the largest in the world. The heliport's sole purpose was to serve the executives and clients of the companies within the building, allowing them to bypass São Paulo's severe road traffic. Operations consisted of private, on-demand VFR (Visual Flight Rules) flights by light helicopters, connecting the office to other heliports, airports, and destinations in the metropolitan area. The 'CBS' in the name likely refers to the original company that registered or was the primary user of the facility. The identifier 'BR-1991' is a non-official code used by third-party aviation databases to track the location, as it did not have a public IATA code and its official ANAC designation is no longer active.

There are no known public plans or prospects for reopening the heliport. For it to become operational again, a tenant or the building's administration would need to apply for a new certification with ANAC, demonstrating that the facility meets all current safety, operational, and regulatory standards. This is a significant undertaking, and its likelihood depends entirely on a future tenant having a specific business need for a private heliport at this exact location. As of now, it is considered permanently closed.
