Auxiliar I Heliport

The official reason for closure is not available. The most probable cause is a combination of economic and regulatory factors. The heliport was the 'auxiliary' facility for the Centro Empresarial Nações Unidas (CENU) complex, which also operates a primary heliport (SDAA) on its West Tower. It is highly likely that the complex's management consolidated all helicopter operations to the single, primary heliport to reduce the significant costs associated with maintaining, staffing, and ensuring regulatory compliance for a second, less-utilized facility.

The physical helipad structure, including the 'H' marking, remains on the rooftop of the CENU's East Tower at Av. das Nações Unidas, 12901. However, it is no longer a licensed or operational heliport. The site is simply the roof of a fully functioning and occupied high-rise office building.

Auxiliar I Heliport (BR-1984) was located on the rooftop of the East Tower of the Centro Empresarial Nações Unidas (CENU), a landmark corporate complex in São Paulo. Its primary function was to provide private air transport for the executives and clients of the numerous multinational corporations housed within the complex. Operating in tandem with the main heliport (SDAA), it catered to the high demand for helicopter travel among São Paulo's business elite, allowing them to bypass the city's severe road traffic. The existence of two heliports on a single business complex highlighted the peak of corporate helicopter usage in the city during its years of operation.

There are no known plans or prospects for reopening the Auxiliar I Heliport. The primary heliport for the complex, 'Centro Empresarial Nações Unidas' (ICAO: SDAA), remains fully operational and is sufficient to handle the current air traffic demand for the site. Re-certifying and reopening a secondary heliport would be economically impractical and is considered highly unlikely.
