Advanced Avionics Maintenance

Chronic Maintenance Deficiencies of ATS/TPS Supported Avionics

• High No Fault Found (NFF)/Can Not Duplicate (CND) rates
• Excessive Maintenance times
• Unmaintainable ATS/TPS
• Insufficient Test Coverage/Excessive Test Voids
• SEI's Approach to Solving the Problem
  • Emphasis on measurable fault detection via computer based tracking of UUT faults vs. test coverage
  • Visual representation of test setups, test flow and signal flow to aid engineers to create accurate test design and fault isolation
  • Use of Sr. Engineers with detailed electronics test experience
  • Development of an interactive on-line maintenance package
