LengyelSubject: Space Shuttle Program/Logistics/Cannibalization Rates, Spares, and Repair Turnaround Times Description of Driving Event: NASA Budget Situ

2、ation Impacts on Shuttle Logistics CapabilitiesLesson(s) Learned: Long-term projections suggest increasing cannibalization rates, component repair turnaround times, and loss of repair capability for the Space Shuttle logistics and support programs.Recommendation(s): Take early remedial action to con

3、trol this potential situation, such as maintaining sufficient spares and extending repair and overhaul capability.Evidence of Recurrence Control Effectiveness: NASA is closely monitoring logistics trends. The areas of emphasis stress long-term logistics support indicators, specifically backlog and r

4、epair turnaround. While an increase in repair turnaround time has been noted, vehicle support remains at the same high level. Budget reductions in past years have meant that fewer spares have been produced and less repairs were performed, but NASA and the contractor will continue to manage the proce

Presently, logistics performance measurement data do not indicate any adverse trends in cannibalization rates.NASA has directed SFOC management to maintain an emphasis on logistics supportability during the transition of all contract responsibilities.

The SFOC has the a

The NASA Shuttle Logistics Depot (NSLD) has been certified to make some repairs where there has been a loss of critical supplier capability. The SFOC is also considering consolidating similar work at one v
