GAO reviewed the National Aeronautics and Space Administration's (NASA) planned development of an alternate high pressure fuel turbopump for the Space Shuttle's main engines, focusing on whether NASA has adequately analyzed cost, performance, and expected program benefits in comparison to other alternatives before resuming its development of the alternate pump. GAO found that: (1) the current engine pump is safe and reliable if existing safety controls are effectively implemented; (2) NASA supports continued development of the alternate pump because of safety concerns about some aspects of the current pump's design; (3) NASA has not analyzed the costs and benefits of modifying the existing fuel pump because a major upgrade will require an expensive full certification test; (4) NASA has not determined what contribution the alternative fuel pump will make to the Shuttle's reliability in conjunction with other engine safety improvements; (5) the alternate fuel pump will require extensive testing and possible redesign as problems occur; (6) NASA did not analyze the costs and benefits of modifying the existing fuel pump and other alternatives before resuming development of the alternate pump; and (7) NASA expects that the alternate pump will reduce operating costs by decreasing inspections and maintenance, but it has not estimated the expected savings. | Space Shuttle Main Engine by U U S Government Accountability Office (, Paperback | Indigo Chapters
