Effectiveness of the Air Force's Neutron Radiography Inspection Systems

摘要

The Air Force maintains facilities at the Sacramento Air Logistics Center containing a Maneuverable Neutron Radiography Inspection System, procured to detect hidden corrosion without disassembly of aircraft, and a Stationary Neutron Radiography Inspection System, procured to detect hidden corrosion in components removed from aircraft. The Maneuverable system became operational in December 1989. The Stationary system became operational in April 1991. The cost to develop and construct the systems was $23.8 million. Our objective was to evaluate the effectiveness of the neutron radiography inspection systems' ability to reduce maintenance costs. Specifically, we determined if joint use by all Military Departments would reduce DoD's weapon system maintenance costs. We also evaluated compliance with laws and regulations and the effectiveness of applicable internal controls.
