🔍 Key Concepts

• 46 CFR Subchapter T requirements for small passenger vessels • Inspection and testing rules for reserve (emergency) power batteries • Difference between periodic inspection intervals (e.g., 3, 6, 12 months) and tests conducted only at the time of inspection

💭 Think About

• Look up the specific CFR section that addresses reserve/emergency power batteries for small passenger vessels and note what it says about testing intervals. • Compare whether the regulation ties battery testing directly to the inspection schedule or to a fixed time interval (or both). • Think about what makes sense for ensuring reliability of emergency power: is it something checked only at formal inspections or also on a more frequent cycle?

✅ Before You Answer

• Verify in 46 CFR Subchapter T the exact phrase regarding when reserve power batteries "must be tested". • Check if the regulation mentions "intervals not exceeding" followed by a specific number of months or if it links testing to the inspection itself. • Confirm whether there is any requirement for testing before each voyage, or if that language appears anywhere in the applicable section.
