Report Date Feb. 8, 1995
Report No. AIMD-95-27
Subject
Summary:

Overall, the Federal Aviation Administration (FAA) has done a credible job analyzing and defining the requirements of the Safety Performance Analysis System, an automated decision support system that FAA is acquiring to help it target its limited inspection and certification resources. However, FAA's current estimates for system software are subjective, not supported by verifiable analysis, and therefore may be unreliable. To identify aviation safety risk precursors, the system depends on information from many databases, including those compromising FAA's Aviation Safety Analysis System. As previously reported by GAO, FAA, and others, these Aviation Safety Analysis System databases contain incomplete, inconsistent, and inaccurate data. If the data quality is poor, the system's input into safety decisions will not be reliable and will not effectively support FAA's inspection and certification system.
