I'm presuming that the ship has a well-equipped TL15 engineering
section, and can make most of the replacement parts as required --
given enough time and engineering expertise.  At the very least, being
able to fashion some version that performs an equivalent function
adequately.

At least in some rules sets, that capability is available at TL13-14,
and should be fairly mature by TL15.
