Certified fuel nozzle MRO for aero and aeroderivative engines

Fuel injectors are robust components providing many years of reliable service. However, they are subject to a hostile environment including thermal cycling, contamination, erosion, crack defects, wear and handling damage. Our FAA and EASA approved repair stations support the global aviation industry with repair services backed by OEM and regulatory approval.

Our experienced engineers have developed DER repair schemes to improve yield during the repair cycle, helping operators save time and avoid the need to purchase high-cost replacement fuel nozzles.

Our fuel nozzle exchange program minimizes downtime by having sets of overhauled fuel nozzles in inventory and ready to ship at scheduled maintenance intervals. The client then sends their old set from the engine to our facility to overhaul and have ready for the next maintenance event.

Comprehensive fuel nozzle MRO services for aviation, aerospace engines, and aeroderivative gas turbines

Aero engine fuel nozzles play a vital role in the safe and reliable operation of modern aero engines. Air blast, pressure atomizing and direct injection technologies ensure turbine engine performance is optimized to improve efficiency and reduce emissions. To maintain this level of performance, operators require support from service provider specialists with the capability to clean, test, overhaul and calibrate these complex components. 

Over time, fuel nozzle performance deteriorates, requiring intervention and remedial action, either on wing or during routine engine maintenance intervals.

Our expertise and experience in repair development and service innovation enables us to deliver high yield fuel nozzle repairs across a wide range of aircraft engine models and aeroderivative gas turbines.
