RAAF Base Amberley has a facility called Engine Test Cell 1 (ETC1) which is used to test aircraft jet engines. ETC1 has an associated Defence Fuel Installation (ETC1-DFI), which supplies fuel for engine testing. The ETC1 upgrade enables the testing of Pratt & Whitney F135 engines for the F-35 and retains the ability to test the General Electric F414 engines for the F/A-18 Super Hornets. Switchboard Innovations were engaged to complete a scope of works around design and documentation, project management and supervision, and supply and delivery of the Main Switch Board (MSB).
