Jabba, believe me, some operators (possibly most) have their maintenance facility at home base and once a twin has been put down on a strip remote from the home base, for engine problems, it is usually a very expensive excersize to get it back. I had been "advised' on many occasions to "bring it home".
Once again it is up to the PIC to make that decision, irrespective of commercial pressures.
To tell tales out of school, I (CFI) was ostracised once by a senior FOI for advising a pilot to put an aircraft down in a good padock should he have continuing engine troubles (single, extreme rough running, surging, loss of altitude). This guy said to me "Can you imagine the costs involved and the logistics to retrieve that aircraft from there!!!! Tell him to nurse it home". I advised the pilot that there were many considerations HE must consider and that he must use his own judgement in making HIS own decision. Commercial pressures......you better believe it mate.
