Specifically, models ASB-60 and ASB-125 that contain power amplifier part number PA-1010B with serial numbers 8366 or below (for 28-volt systems) or 5383 or below (for 14-volt systems).\n\n**What must be done:**\n1. **Modify the equipment** following the manufacturer's instructions in Sunair Service Bulletin No. 60/125-001 (dated April 1974).\n2. **Permanently mark the equipment** by adding \"-001\" next to the PA-1010B connector so future inspectors can see the modification has been completed.\n\n**Deadline:** The work had to be completed before 31 March 1977.\n\n**Why it matters:** This prevents potential failures in critical aircraft communication systems. HF radios are essential for long-distance communication, especially over oceans or remote areas where other signals don't reach."}},"importantCases":[],"_links":{"self":"/api/acts/ad-rad-30-sunair-hf-transceiver-modification","history":"/api/acts/ad-rad-30-sunair-hf-transceiver-modification/history","analysis":"/api/acts/ad-rad-30-sunair-hf-transceiver-modification/analysis","conflicts":"/api/acts/ad-rad-30-sunair-hf-transceiver-modification/conflicts","importantCases":"/api/acts/ad-rad-30-sunair-hf-transceiver-modification/important-cases","documents":"/api/acts/ad-rad-30-sunair-hf-transceiver-modification/documents"}}
