🔍 Key Concepts

• 46 CFR requirements for tailshaft inspection and withdrawal • Authority of the Coast Guard Commandant versus classification societies like ABS • Difference between regulatory authority (CFR) and industry/owner personnel

💭 Think About

• Which of these choices actually has legal authority to change or extend an inspection interval that is written into federal regulations? • Are ABS and company engineers regulators, or do they work under/alongside the regulatory framework set by someone else? • When 46 CFR says an interval "may be extended," whose approval is normally required for such a deviation from the standard schedule?

✅ Before You Answer

• Check who is explicitly named in 46 CFR Subchapter I – Inspection and Certification as having authority to grant extensions or exemptions • Verify whether classification societies like ABS are mentioned as regulators or as recognized organizations acting under Coast Guard oversight • Confirm that company technical staff (like port engineers) can propose or request, but do not themselves grant, regulatory extensions
