The fuse must be in a holder permanently attached to the equipment. **Who it affects:** Aircraft owners, operators, and maintenance providers responsible for these specific radio models. **Why it matters:** The fuse acts as a circuit breaker to prevent electrical fires or equipment damage if the radio shorts or draws too much current. An engineering order from Rex Aviation (EO No. 191) provides the approved method for making this change."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rad-9-amdt-1-rexair-amspeaker-fuse-installation","history":"/api/acts/ad-rad-9-amdt-1-rexair-amspeaker-fuse-installation/history","analysis":"/api/acts/ad-rad-9-amdt-1-rexair-amspeaker-fuse-installation/analysis","conflicts":"/api/acts/ad-rad-9-amdt-1-rexair-amspeaker-fuse-installation/conflicts","importantCases":"/api/acts/ad-rad-9-amdt-1-rexair-amspeaker-fuse-installation/important-cases","documents":"/api/acts/ad-rad-9-amdt-1-rexair-amspeaker-fuse-installation/documents"}}
