Leading Edge Flap Transmission

Using the UL101 receiver with a solid probe, an aircraft technician can quickly listen to the ultrasonic output of each hydraulic component.

Flap Control Valve & Bypass Valve

Before initiating the repair, a member of Southwest’s Maintenance Operations Center decided to investigate the aircraft using the UL101 Aviation Troubleshooter Kit.

CTRL Technology has a Long History of Aircraft Maintenance Innovation.

In early 2019, BCA’s PMET group approached CTRL Systems regarding an innovative ultrasound solution. We were selected, in part, due to our history in the aerospace industry — including prior vetting, selection, and integration for support and readiness on various platforms:

  • NASA’s use on the International Space Station (ISS)
  • All NASA shuttles from 2004 until retired
  • Lockheed Martin F-35 Lightning II Joint Strike Fighter

Boeing Commercial Airplanes (BCA) and CTRL Systems: Partners in Innovation

The Boeing Commercial Airplanes (BCA) Predictive Maintenance and Enhanced Troubleshooting (PMET) team and CTRL Systems have come together to offer an innovative solution for aviation diagnostics and troubleshooting of all Boeing Commercial Jet Aircrafts through acoustic ultrasound technology. The “Charlies Works” Team is a part of BCA’s PMET division. The mission of this highly-skilled team is to rapidly locate and integrate innovative solutions to difficult chronic airplane systems, tailored to the needs of the Aircraft Maintenance Technician (AMT). Once discovered, new solutions are vetted for quick and effective implementation and published in the Aircraft Maintenance Manual (AMM), as “Charlie Works” continues to to collect and share knowledge within the commercial aviation industry.

CTRL Systems is the designer and manufacturer of advanced acoustic ultrasound technologies and turnkey monitoring solutions for industries around the world. From paper mills in the United States to power plants in China, from U.S. Navy vessels around the world and all the way to the International Space Station (ISS), CTRL ultrasound technology helps the world to run efficiently and on on time. In addition to our work delivering cloud-based condition monitoring solutions to industry, we possess a long, successful history of delivering Aircraft on Ground (AOG) diagnostic solutions into both government and commercial aviation markets. For more than 20 years, our technology has been used for fleet readiness, AOG diagnostics, and quality control by the United States Air Force, NASA, the United States Navy, Boeing Engineering, Airbus, United Airlines, Cirrus Aircraft, Northrop Grumman, and many others.
