Alaskan Airplane Maintenance  "Serving Alaska For Over 30 Years" Corrosion Proofing Frequently Asked Questions Back To Corrosion Q. Is ACF-50 approved by the US Government?       A. Yes ACF-50 is U.S Government performance qualified to Mil-C-81309E, amd.2 Type II and Type III. Q. Does ACF-50 meet any other aerospace industry standards or have any O.E.M. approvals?       A. Yes, ACF-50 meets a number of industry performance requirements  some of which are listed ,as well as having over             fourteen O.E.M. recommendations. Q. What does the FAA think about ACF-50?       A. AC F-50 meets FAA criteria and therefore can be an acceptable general corrosion preventative for use on aircraft. Q. Is ACF-50 Toxic?      A. No. Complete toxicology tests (oral-eye-dermal) have been performed on AC F-50 by world renowned           Hazelton Laboratories. Their testing concluded that ACF-50 is Non-Toxic according to EPA and OCED standards. Q. Does ACF-50 meet US State requirements for Volatile Organic Content (VOC)?       A. Yes ACF-50 is VOC compliant in all fifty states at a meager 16%. This puts us well below even the tough air quality control             regulations in C California. Q. How often does ACF-50 need to be applied to the airframe?      A. We recommend a minimum of once every two years. Shorter or longer intervals will be prescribed depending on           the aircraft's operational environment. Q. What type of equipment is used to apply ACF 50?       A.  Pressurized wands, that creates an atomizing dense wet fog for thoroughly coating the surface being treated. Q. Does ACF-50 loosen rivets?       A. No. AC F-50's Low shear formula will penetrate around a tight rivet removing moisture without causing it to loosen.            Unlike other products ACF-50 does not Contain EP (extreme pressure) additives. The presence of these undesirable           additives could cause rivets  to loosen and fraying surfaces to loose their structural cohesiveness. Q. Will ACF-50 harm aircraft plastics, paint, or wiring?       A. AC F-50 was tested for stress crazing on acrylic plastic and for effect on aircraft grade paints with both tests showing            no deleterious effects. ACF-50 was tested on polyamide insulated wire and found to have no negative effects.
