GS Engineering was tasked to reverse engineer a critical aircraft braking system component to allow procurement of replacement parts. The effort entailed 3D scanning, probing of sample components, optical electron spectroscopy, mechanical material testing for alloy and temper identification, an investigation into relevant standards and testing, and an investigation of interfacing components to determine tolerance class for component features. These efforts resulted in the design, analysis, technical data package production, and prototype production of the replacement component. The prototype components were fit tested to ensure proper form and fit and then tested according to the previously identified standards to ensure proper function. These activities will support a production run of parts to supply the components necessary to keep the fleet of CAL FIRE aircraft operational.
