CTRL UL101 Aviation Troubleshooter
Acoustic Ultrasound Detection System for Precision Aviation Maintenance
The CTRL UL101 Aviation Troubleshooter is an industrial-grade ultrasonic detection system that assists technicians in rapidly pinpointing pneumatic, hydraulic, electrical, and mechanical faults in aircraft maintenance. Operating at 40 kHz, the UL101 demodulates ultrasonic frequencies into the audible range, providing an intuitive and non-destructive method for identifying issues that traditional methods often miss. With a proven 100% ROI within the first use, this tool transforms time-consuming troubleshooting into precise, data-driven diagnostics.
Boeing 737 MAX — CFM LEAP 1-B Fuel Nozzle Inspection
Case Study 1 of 4
1The Problem
A Boeing 737 MAX CFM LEAP 1-B engine developed a recurring fuel nozzle anomaly. Traditional troubleshooting required borescope inspection and often led to blanket replacement of all 18 fuel nozzles — consuming hours of engine downtime and introducing contamination risk each time the combustor was opened.
2The Solution
Technicians deployed the UL101 Aviation Troubleshooter (B00033) to listen for the ultrasonic signature of internal leakage at each nozzle. Within minutes the single defective nozzle was isolated acoustically — without any borescope or intrusive disassembly.
3The Results
- Reduced diagnostic time to under 60 minutes
- Eliminated borescope contamination risk
- Identified the single failing nozzle vs. replacing all 18
- No special certification required for technicians
- Returned the engine to service the same shift
