As you know, certain areas of the country and across the globe offer harsher operating environments than others.
These areas are identified in FAA AC 43-4A references “Corrosion Control for Aircraft.” If you operate your aircraft in these areas or other salt laden, corrosive or other polluted environments, consider compressor and turbine washes to extend the useful life of gas path components.
PWC Service Information
Letter (SIL) PT6A-206 references “Compressor and Turbine washes” as an effective means of preventative maintenance.
Your maintenance manual (MM) also provides a table matching the environment with a suggested wash and frequency. Reference the applicable PWC MM 71-00-00, Cleaning, for your requirements, recommended frequency, and procedures. You may also contact DAI for guidance. Find your Regional Engine Manager here
