Lessons Learned – Criticality of Hardware Refurbishment Process
Year: 1999
Abstract: Description of Driving Event:
Shortly after launch of STS-90, some of the motors/air-pumps associated with the aquatic habitats exhibited an increased power draw indicating either motor or pump failure. To successfully complete the mission, an in-flight procedure was utilized to cross-link each habitat to an operational air pump. Upon landing and recovery, an investigation was conducted of the failed motor/air-pump assemblies to determine why some units failed while others performed normally. The investigation determined that all of the units that operated properly were original equipment manufacture units, and the units that failed had all been refurbished.
