Rob Wansker, FRCE V-22 Power and Propulsion Auxiliary Power Unit (APU) senior engineer, indicates the location of the clutch servo-valve filter on a V-22 Osprey APU. Wansker’s team developed a process to clean these filters after a supply backlog made the critical filters briefly unavailable to Navy and Marine Corps maintainers.
