Embraer Defense & Security has selected AMETEK Sensors & Fluid Management Systems (SFMS) as a supplier for the US Air Force's (USAF) recently awarded light air support (LAS) contract.

Secured by the team of Embraer and Sierra Nevada Corporation (SNC) in February, the $427.5m contract covers delivery of a total of 20 A-29 Super Tucano aircraft to help the Afghanistan Air Force (AAF) address its security requirements.

Under the contract, the company will supply its advanced triaxial accelerometers and AMPHION solid-state relays (SSR) for installation onboard the A-29 Super Tucano aircraft.

Commenting on the contract, AMETEK SFMS vice president and business unit manager Andy Brandenburg said the company is looking to support Embraer in developing the aircraft for the USAF's critical mission.

Fully designed to 573 and 717 ARINC specifications, AMETEK triaxial accelerometers enable simultaneous measurement of acceleration along vertical, longitudinal and lateral axis.

Already tested to TSO C51a and the Radio Technical Commission for Aeronautics (RTCA) DO-160 standards, the accelerometers also address mandatory requirements of the US Federal Aviation Administration (FAA), and other worldwide regulatory agencies.

Leveraging AMETEK's patented fail-open technology for reliable electrical power control, the AMPHION SSR can perform switch power, current / voltage monitoring and arc fault detection.

The system combines the functions of a power contactor and an arc fault circuit breaker in one small and efficient module that can fit into a standard M12883/48-02 sockets and switch up to 25A at 28VDC.

Covering delivery of associated maintenance and training support to the AAF, the LAS contract forms part of US support to the country following strategic withdrawal at the end of next year.

The aircraft, which is expected to be delivered in the summer of 2014, will be used for conducting advanced flight training, surveillance, close air support or ground troops and air interdiction missions.
