Why do No Fault Found conditions persist? When is a NFF condition the actual source of the problem or a symptom reflecting an unidentified problem somewhere else? Why does a failure mode repeat and does it exist in my fleet alone? Do persistent NFF conditions and repeating failures cause components to be declared obsolete prematurely? How much leakage is spilling out of operating budgets and how many unnecessary personnel and asset risks exist because of these problems? Am I alone or can anyone help?

Since 1995, ULTRAX Aerospace, Inc. has used empirically driven scientific methods in our Investigative Laboratory to analyze the problem domains causing NFF, recurring failures and obsolescence. Our Investigative Laboratory exists to determine the root cause of these problems and identify the best ways to prevent them. By converting the facts and occurrences of a problem domain into useful knowledge, our Investigative Laboratory helps us develop the diagnostics and business intelligence tools that are used to:

  • Strategically and systemically manage fleet lifecycles
  • Quickly and accurately solve unscheduled problems on either the flight line or the bench
  • Isolate changes and differences in aircraft electrical configurations
  • Perform proactive maintenance
  • Prevent false pulls (NFF)
  • Eliminate recurring failures
  • Prevent AOG
  • Plan and manage obsolescence
  • Avoid spares pool supply chain imbalances and shortages
  • Prevent AOG
  • Maximize return on assets
  • Maximize mission-readiness
  • Reduce personnel and asset risks
  • Improve operating budgets

Whether the development of a flight line or bench level diagnostics tool, a simple behavior change or a revision to a manual, we engineer outcomes that come together, enabling the maintainer/technician to more efficiently and effectively manage their moment of need on the ground. Systemic efficiencies and risk reductions are created that possibly saves billions for aerospace and industrial organizations.

Demystifying complex aircraft systems to limit NFF

No Fault Found is expensive, wasteful and avoidable. Patterns in electrical systems are a natural byproduct of the diagnostic testing that reveals what is out of spec and what is a fault. Our Investigative Laboratory uses empirically driven scientific methods to analyze the problem domain patterns causing NFF, recurring failures and obsolescence of complete and complex systems. The knowledge and power to challenge the status quo across design, manufacturing and maintenance to limit the impact of NFF comes with identifying recurring patterns.

Turning diagnostic data from bench and on-aircraft diagnostic scans into actionable knowledge

Our Lab is unique in that it integrates on-aircraft diagnostic modes with bench diagnostic modes to expand the breadth and depth of relevant data points from which actionable knowledge is derived. Both diagnostic modes benefit from the results of applied scans taken all over the world by the others. Those experiences on the bench and on aircraft are analyzed and converted into actionable knowledge.

Applying groundbreaking knowledge in real time

ULTRAX continually adapts its application software framework (AF) on the bench and on the flight line to integrate our most up-to-date knowledge of problem domains. This knowledge continuously improves the quality of the applied test whether on the bench or the flight line. Also, the application framework is adaptive to work with and enable an installed base of non-ULTRAX test sets, resulting in multiple data streams being evaluated by our Investigative Laboratory.
