Aircraft manufacturer structural repair manuals (SRMs), FAA Advisory Circulars, and process specifications such as Boeing BAC 5763, Airbus APS 2500, and the AMS 2430\/2431\/2432 series define acceptable media, process parameters, and quality verification methods with zero tolerance for deviation. The consequences of non-compliant blasting \u2014 substrate dimensional change, media embedding, fibre exposure in composites, metallurgical alteration from excessive peening \u2014 range from costly component rejection to airworthiness certification withdrawal.<\/p>\n<p>Abrasive media for aerospace blasting must be certified to the applicable specification, lot-traceable, and accompanied by certificate of conformance documentation. Using non-certified media in an MRO blasting operation is both a quality system violation and a potential airworthiness concern.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-media\">\n<h2 class=\"hlh-cl-h2\" id=\"hlh-cl-media\">Media Selection by Aerospace Component<\/h2>\n<div class=\"hlh-cl-table-wrap\"><table class=\"hlh-cl-table\">\n<thead><tr><th>\u6210\u5206<\/th><th>Substrate<\/th><th>Recommended Media<\/th><th>Specification<\/th><\/tr><\/thead>\n<tbody>\n<tr><td>Aluminium fuselage skin<\/td><td>2024-T3, 7075-T6 Al<\/td><td>Plastic media Type I or II<\/td><td>MIL-P-85891A<\/td><\/tr>\n<tr><td>Composite fairings \/ radomes<\/td><td>CFRP, fibreglass<\/td><td>Plastic media Type III or walnut shell<\/td><td>MIL-P-85891A<\/td><\/tr>\n<tr><td>Titanium structural parts<\/td><td>Ti-6Al-4V<\/td><td>Glass beads (peening)<\/td><td>AMS 2431\/6<\/td><\/tr>\n<tr><td>Steel landing gear<\/td><td>300M, 4340 steel<\/td><td>Steel shot (peening)<\/td><td>AMS 2430<\/td><\/tr>\n<tr><td>Turbine blade (Ni superalloy)<\/td><td>IN718, Waspaloy<\/td><td>Aluminum oxide or glass beads<\/td><td>Engine OEM spec<\/td><\/tr>\n<tr><td>Magnesium castings<\/td><td>Mg alloy<\/td><td>Plastic media Type III<\/td><td>MIL-P-85891A<\/td><\/tr>\n<tr><td>Engine nacelle (Al)<\/td><td>Aluminium sheet<\/td><td>Plastic media Type I<\/td><td>MIL-P-85891A<\/td><\/tr>\n<\/tbody>\n<\/table><\/div>\n<\/section>\n\n<section id=\"hlh-cl-skin\">\n<h2 class=\"hlh-cl-h2\">Aircraft Skin Paint Stripping<\/h2>\n<p>Commercial aircraft require complete paint removal at scheduled heavy maintenance intervals (typically C-check and D-check) to inspect the underlying structure for corrosion, fatigue cracks, and repair quality. Plastic blast media (Type I: urea, Type II: melamine) is the aerospace-standard method for stripping polyurethane topcoat and epoxy primer from aluminium skin without dimensional change to the substrate.<\/p>\n<p>The critical process control requirements are: blast pressure limited to the SRM maximum (typically 40\u201360 psi); verified zero metal removal using eddy-current thickness gauge before and after blasting; media lot certification to MIL-P-85891A; and spent media testing if the stripped coating system contains lead or chromate. For the full plastic media technical guide, see <a href=\"https:\/\/hlh-js.com\/resource\/blog\/plastic-blast-media-for-sandblasting\/\" target=\"_blank\" rel=\"noopener\">Plastic Blast Media guide<\/a>.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-turbine\">\n<h2 class=\"hlh-cl-h2\">Turbine &amp; Engine Component Blasting<\/h2>\n<p>Gas turbine hot section components \u2014 compressor blades, turbine blades, and vanes \u2014 require careful blasting for coating removal, bond coat preparation before thermal spray, and carbon\/oxidation cleaning during overhaul. White aluminum oxide (WFA) is commonly used for thermal barrier coating bond coat preparation on nickel superalloy substrates, producing the angular 2.0\u20133.5 mil profile required for HVOF or plasma spray adhesion without introducing iron contamination from BFA or metallic media.<\/p>\n<p>Carbon deposits on turbine blades (from hot section operation) are removed with fine walnut shell or fine glass beads \u2014 gentle enough to clean without altering the blade&#8217;s precision aerodynamic profile. Any dimensional change to a turbine blade from abrasive impact is grounds for rejection: blade tip clearance tolerances are typically \u00b10.1 mm, and any reduction in blade thickness changes the structural integrity calculation.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-peening\">\n<h2 class=\"hlh-cl-h2\">Shot Peening in Aerospace<\/h2>\n<p>Shot peening is a compressive stress-inducing surface treatment used to extend fatigue life of aircraft structural components: springs, landing gear, wing spars, and turbine components. The process uses certified shot media (steel shot, glass beads, or ceramic beads depending on substrate) propelled at controlled velocity to produce a specific Almen intensity, measured in thousandths-of-an-inch arc height on standardised Almen strips.<\/p>\n<p>Glass beads (AMS 2431\/6) are specified for peening aluminium and titanium components where steel contamination must be avoided. Steel shot (AMS 2430) is used for steel landing gear, springs, and high-strength steel components where maximum peening intensity is required. All aerospace peening operations must be performed to written process specifications with documented intensity, coverage, and media certification verification. For full glass bead peening guidance, see the <a href=\"https:\/\/hlh-js.com\/resource\/blog\/glass-bead-sandblasting-abrasive\/\" target=\"_blank\" rel=\"noopener\">Glass Bead guide<\/a>.<\/p>\n<\/section>\n\n<section id=\"hlh-cl-compliance\">\n<h2 class=\"hlh-cl-h2\">Regulatory Compliance for Aerospace Blasting<\/h2>\n<p>All blasting media used in aerospace MRO must meet the following minimum documentation requirements: Certificate of Conformance to the applicable AMS or MIL specification; current Safety Data Sheet (SDS\/MSDS); lot traceability documentation; and, for peening shot, Almen strip test results from the production lot. Media that cannot be traced to a certified production lot must not be used in certified aerospace blasting operations regardless of apparent visual quality.<\/p>\n<p>OSHA 29 CFR 1910.1053 respiratory silica requirements apply to aerospace blasting operations; however, most aerospace-approved media (plastic, glass beads, aluminium oxide) are silica-free, simplifying compliance.
