Normally, if you want to produce spare parts or modifications for certified aircraft, you need a specific production approval (called a \"production certificate\" under regulation 21.303). This instrument lets certain manufacturers skip that requirement.\n\n**Who it affects:** Companies that manufacture replacement parts or modifications for type certificated aircraft, engines, or propellers — specifically those who don't already hold the usual production approval.\n\n**The catch (conditions):** While manufacturers don't need the production certificate itself, they must use manufacturing processes that CASA has already approved under regulations 21.305 or 21.305A. This ensures safety standards are maintained even without the full certification paperwork.\n\n**Key limitation:** This was a time-limited exemption only, effective from registration until the end of October 2010."}},"importantCases":[],"_links":{"self":"/api/acts/casa-ex97-09-exemption-to-produce-a-modification-or-replacement-part","history":"/api/acts/casa-ex97-09-exemption-to-produce-a-modification-or-replacement-part/history","analysis":"/api/acts/casa-ex97-09-exemption-to-produce-a-modification-or-replacement-part/analysis","conflicts":"/api/acts/casa-ex97-09-exemption-to-produce-a-modification-or-replacement-part/conflicts","importantCases":"/api/acts/casa-ex97-09-exemption-to-produce-a-modification-or-replacement-part/important-cases","documents":"/api/acts/casa-ex97-09-exemption-to-produce-a-modification-or-replacement-part/documents"}}
