We also offer Borescope Inspections for both Honeywell TPE331 and Pratt & Whitney PT6 Engines. This will show you the condition of your engine and can be performed either at your facility or ours.

Fuel Nozzle Program
Fuel Nozzle Maintenance and Overhaul is the major factor affecting the life and performance of turbine engine hot sections. Honeywell recommends replacement every 400 hours for simplex nozzles and 350 for duplex nozzles. Prat and Whitney recommends replacement at 400 hours for simplex and duplex nozzels. We recommend replacement every 300 hours for both types of nozzles for both types of engines. This will help extend the life of your hot section and keep it from looking like the hot section pictured. Being diligent about this critical maintenance procedure will save the operator money over the life of the hot section. Borescoping at nozzle changes can help monitor hot section wear and help catch damage before it becomes a costly repair.
Our Fuel Nozzle Overhaul and Exchange Program for both Pratt and Whitney PT6 and Honeywell TPE331, that will help get you back up and running faster with a quicker turn around time if time is a factor for you. Contact us today for your next PT6 or TPE331 fuel nozzle overhaul.
