Without wishing to comment on this specific incident, because who knows what the truth was behind the newspaper reports.....
Most/many rules sets pertinent to commercial Ops state that if an engine is not capable of producing "go-around" power then it should be treated to all intents and purposes as failed. Most of those rule sets also state that for a twin if you have an engine failure then one should land at the nearest suitable airfield, as ironbutts says servicing doesn't enter into it.
Just saying...
