Actually, Lieutenant Commander Leland T. Lynch™ is a registered trademark in the 24th Century.To nitpick, he wasn't a CHIEF engineer. Just somebody down at the Engineering who felt he needed to identify himself by full name and rank the first time around - thus, probably some underling, or perhaps a visiting specialist.You forgot "Leland T. Lynch!"

Interestingly, Memory Alpha lists him as a Chief Engineer, albeit somewhat controversially:
