Product Code:SAE AIR4416
Title:Helicopter Turbine Engine Wash
Issuing Committee:S-12 Helicopter Powerplant Committee
Scope: Engines subject to dust, industrial pollution, saltwater contamination or other chemically laden atmosphere (including pesticies and herbicides) lose performance due to deposits of contaminants on surfaces in the air/gas flow path. Engine wash and engine rinse procedures are utilized to restore turbine engine performance. These procedures are generated by the engine manufacturer and are included in the Engine Maintenance/Service Manuals. For most turbine engines these procedures are similar in concept and practice; however, application details choice of solvents and many other service features can vary from engine manufacturer to engine manufacturer and may even vary within the range of engine models produced by any manufacturer. The intent of this SAE Aerospace Information Report (AIR) is to outline the general nature, considerations, and background of engine wash and engine rinse and is directed towards the needs of the entry level engineer, service engineer, and those involved in the general maintenance of installed turbine engines.MIL-I-46058C, MILITARY SPECIFICATION: INSULATING COMPOUND, ELECTRICAL (FOR COATING PRINTED CIRCUIT ASSEMBLIES) (07 JUL 1972) [NO S/S DOCUMENT]., This specification covers conformal coatings which are suitable for application to printed circuit assemblies by dipping, brushing, spraying, or vacuum deposition.
