Prefix symbols are defined as follows: AMS − AmericanMaterial Standard; MS − Military Standard; MIL − Military Specification; Single, double or triple alpha prefixof same letter − Federal Specification; AN − Air Force−Navy Aeronautical Standard; NAS − NationalAerospace Standard.(2) Primary selection. Any equivalent material may be used as an alternate selection.(3) Use best comparable grade material when conformity of available materials of same type with listedSpecification No. cannot be determined.(4) Several types of original protective treatment are used on magnesium alloy parts. With paint removed,treatment process should be identifiable from coating appearance as outlined in following table. Partsshould not be reprocessed either completely or partially without first contacting MDHI Customer ServiceDepartment. However, regardless of original process used, chromic acid brush−on treatment (Dow #19, orequivalent) is acceptable for touchup of coatings removed by abrasion, scratches or rework.(5) When ordering paint from Advance Coating and Chemicals, specify each paint by type (i.e., acrylic, epoxy,polyurethane), by color, and by AC part number. Also include compatible HS or Fed. Std. No. to ensure thatcorrect type and color paint is provided. The color code numbers for finish paints used on new Model 369helicopters are now being entered in helicopter log books prior to delivery of aircraft. Owners/operators ofearlier models should check sales order for paint numbers listed and enter them in some log books, orsales orders. If so, ensure when ordering Advance Coating paints that AC No. and SA No. are compatible.(6) Do not use over 50 psig air pressure for abrasive cleaning method. Mask or shield threaded areas orcritical surfaces where damage may result from abrasive blasting.Page 2−31TR09−001
