Under 14 CFR §91.207 (for US operators), ELTs must be inspected within 12 months of the last inspection for battery life, corrosion, and proper mounting. But the regulation points directly to manufacturer instructions. That is where the Air Precision ELT 96 Maintenance Manual becomes a legal document.
Every 48 months from date of manufacture OR 1 hour of cumulative transmit time. Connect a wattmeter and dummy load
The manual states that Voltage Standing Wave Ratio (VSWR) must be less than 2:1 at 406 MHz. Without a proper antenna analyzer, you won’t know that a cracked antenna base or water ingress has destroyed performance. The manual’s troubleshooting flowchart points directly to this as a leading cause of failed satellite detection.
Over the past decade, the FAA has issued dozens of violations related to ELT maintenance. Here are real-world examples where the Air Precision ELT 96 Maintenance Manual would have prevented the issue: Under 14 CFR §91
