🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) shore-based maintenance and inspections requirements in 47 CFR Part 80 and 46 CFR where applicable • Who is authorized to perform a GMDSS ship radio station inspection (FCC, Coast Guard, or specific license holder) • Required time interval for GMDSS radio station inspections to keep the Safety Radio Certificate valid

💭 Think About

• Ask yourself: Which option matches the standard GMDSS radio safety certificate validity and renewal/inspection cycle used internationally under SOLAS? • Consider whether routine preventive maintenance by crew or maintainers can legally replace a formal regulatory inspection and certificate issuance. • Think about which U.S. authority is normally responsible for certifying GMDSS radio installations on SOLAS‑class vessels trading internationally.

✅ Before You Answer

• Verify the required maximum interval (in months or years) for formal GMDSS ship radio station inspections in current FCC/USCG guidance. • Check which person or authority is explicitly allowed to carry out a GMDSS ship radio station inspection (e.g., FCC inspector vs. individual with a specific GMDSS license). • Confirm whether on‑board preventive maintenance alone is ever stated as sufficient to meet the formal inspection and certification requirement.
