Alternate cleaning product for aircraft oxygen systems
Aircraft owners, operators, maintenance organisations and maintenance personnel.
To provide information to the Australian Aviation Industry on a product that may be suitable for a wide range of maintenance tasks including cleaning Aircraft Oxygen Systems.
CASA has been contacted by industry looking for suitable products for cleaning Oxygen Systems, such as 3M Novec HFE.
Oxygen system and component cleanliness is of the utmost importance. Cleaning materials should leave the product oil or grease free and have no residual effect that may provide any contamination of the inhaled oxygen, hence there are limited products that may be suitable for use in maintaining and servicing these systems.
This non-flammable, and described as an essentially non-toxic, fluid offers zero ozone depletion potential for varied cleaning and drying needs and may be used as alternatives to CFCs' HFCs, HCFCs and other similar or flammable solvents. Applications include particulate and fluorinated oil or grease removal, as a carrier solvent and for heat transfer. The product also has potential for application in other areas of aircraft or aircraft component maintenance.
Properties of this product may make it suitable as a moisture displacing fluid for cleaning aircraft electrical connectors.
Approval for use
The product has been listed as suitable for cleaning oxygen systems by both Boeing and the US Military and has been qualified against a number of military and civil standards
Caution: CASA reminds aircraft owners, operators, maintenance organisations and maintenance personnel that unless a product has been approved by the aircraft or aircraft component manufacturer as appropriate for a particular maintenance task then a proper assessment and subsequent approval under CAR36A to authorise the use of the product is required.
The product is a "Hydrofluoroether" and is marketed by 3M. The trademark registered by 3M corporation is Novec HFE.
