Liebherr enhances aircraft maintenance with bleed air leak detection

Aerospace maintenance, aircraft systems monitoring, and airline operations require efficient fault detection to minimize downtime and maintain performance. In this context, Liebherr-Aerospace has signed a service agreement with GoJet Airlines to deploy its bleed air leak finder solution across the airline’s fleet of more than 50 Mitsubishi CRJ aircraft.

The agreement focuses on improving the detection and localization of leaks within aircraft bleed air systems, which are critical for functions such as cabin pressurization and environmental control. Inefficient leak detection can lead to extended maintenance times and reduced system performance.

Integration with onboard leak detection systems
The solution complements the aircraft’s embedded Bleed Air Leak Detection System (BLDS), which uses a network of sensors positioned along the bleed air system to detect leaks and transmit data to a monitoring controller. While BLDS identifies the presence of a leak, Liebherr’s tool enhances the troubleshooting process by enabling faster localization.

3D visualization for faster fault identification
The leak finder introduces a 3D visualization interface that guides maintenance personnel through a two-step process to pinpoint the exact location of a leak. This reduces reliance on manual inspection and accelerates diagnostic procedures, particularly in complex aircraft systems where accessibility may be limited.

By improving visibility into system behavior, the tool supports more systematic analysis of faults and reduces uncertainty during maintenance operations.

Reduced maintenance time and improved planning
The implementation of the leak finder is expected to reduce the average duration of maintenance activities related to bleed air leaks by approximately 33%. Shorter troubleshooting cycles allow for more precise maintenance scheduling and improved aircraft availability.

This contributes to lower operational costs and reduced downtime, which are critical factors for regional airlines operating high-frequency flight schedules.

The agreement represents an expansion of Liebherr’s health management solutions, which are designed to support predictive maintenance and optimized repair processes. By combining onboard detection systems with advanced visualization tools, the company aims to improve efficiency in aircraft maintenance workflows.
