CiES Incorporated Receives ANAC Approval for Installations in Brazil

CiES Incorporated announces that it has received approval from Brazil’s National Civil Aviation Agency (ANAC) for the installation of CiES fuel quantity systems on eligible aircraft registered in Brazil.

The approval authorizes installation under ANAC Supplemental Type Certificate No. 2023S09-08 and its associated approved model list, enabling CiES magneto-resistive fuel senders to be installed in accordance with approved data on covered aircraft models.

This ANAC approval expands access in Brazil to CiES’ unmatched fuel quantity technology, which eliminates mechanical wear components and provides stable, repeatable measurement performance when compared with traditional resistive float-based and legacy capacitance systems.

CiES Incorporated will continue to support Brazilian operators, maintenance organizations, and installation facilities with approved documentation, installation guidance, and ongoing technical support.

For information regarding aircraft eligibility or installation requirements, please contact CiES Incorporated or an authorized installation provider.
