No it would not. Return to base is usually preferable. When could the Engineer get out there?.....'next flight?'. Could be next day. Maybe it needs more than one head, and access to spares. So wait at least 12 hours to get an engineer out there, then he orders spares...er wait a minute- they have to come out on the next next flight. Woops, crew are out of hours in Corfu- have to go to hotel and they need 12 hours! Better to get back to base, crew change, quick repair and go.
