I bought Jenna a better ship (a Minotaur frigate?), which has been damaged in battle (armor down to 92%). Unfortunately, she does not repair it on Commonwealth stations any more.

Wingmen only repair if armor is below 90%.

Thanks for the info - trying to confirm by leading Jenna into another battle

Can confirm: armor must be at least 90% damaged.
