Who is authorized to extend the ten-year reduction gear inspection?

The authorization to extend the ten-year reduction gear inspection lies with the Type Commander (TYCOM) under certain specific conditions. This is based on naval regulations that allow for flexibility in inspection schedules contingent on the operational status and maintenance history of the vessel. The TYCOM has the broader overview of the fleet and can allow extensions based on criteria such as the gear's condition, maintenance performed, and the ship's operational requirements.

This authority helps ensure that extensions are granted judiciously and are backed by proper assessments rather than solely depending on one individual or department's discretion. The ability to make adjustments to inspection schedules can optimize operational readiness while maintaining safety and reliability in critical systems like reduction gears.

In contrast, the Commanding Officer, Chief Engineer, or Naval Shipyard may not have the authority or the systemic oversight to make such a decision regarding inspection extensions, which is specifically designed for TYCOM’s operational management role.
