The National Research Council’s (NRC) Flight Research Laboratory (FRL) operates a Convair 580 aircraft for flight research. As the aircraft is frequently modified and/or operated in a manner different to the original design purpose, engineering support from the holder of the aircraft’s Type design and intellectual property is frequently required. As a result, the FRL requires a contract to provide engineering services and support related to the Convair 580 aircraft. This work will involve engineering studies and/or modifications to the Convair 580 to support external sensors, on-going maintenance/repair and technical support.
