CTMA Project #: 110458
Problem: Achieving acceptable pressurization levels on aging airframes is an increasing challenge, requiring more manhours and increased fuel costs. The traditional methods of feeling for leaks are no longer adequate. These methods are time consuming, cannot be used in confined areas, and are overall less than effective. Relying on these inefficient methods increases maintenance downtime, reduces aircraft availability, increases manhours, and significantly increases fuel costs.
Solution/Approach: The purpose of this project is to test acoustic imaging cameras to see if implementation of the technology increases aircraft availability by identifying pressurization leaks more quickly and accurately than traditional methods. In addition, the project will seek to quantify the elimination of rework, reduction in man-hours and fuel costs produced as by-products using the cameras. The acoustic camera’s ability to identify pressure leaks in other aircraft/equipment/facility systems will also be tested (i.e. fire suppression systems (FSS), nitrogen inerting systems, oxygen systems, bleed air, hangar FSS, industrial shop air).
Benefit: Use of this technology will increase overall aircraft availability by reducing maintenance downtime. The ability to identify pressurization leaks quickly and more accurately will eliminate rework, reducing both manhours and fuel costs.
