Air Technology Engines received FAA Approval to repair the T53 Combustion Liner. This improves airflow to the gas producer blades and nozzles. The repair improves fuel efficiency and reduces damage caused by unburned fuel particles(carbon ball blasting) eroding the blade tips. Extensive testing established measurable improvements to combustion efficiency compared to the current combustion liner configuration. Operators may receive the repaired liner during mid life inspection or overhaul.
