Twice Proves it
Not forgetting that BA thumbed its nose at FAA concerns by doing a 3eng long-haul with pax from Singapore to Heathrow the following week in the same airframe after the replacement engine also failed.
Not long after that we had all the revelations from the UKCAA about BA's maintenance shortcomings (and with plenty of evidence to back those assertions up).
Even without the EU directives on passenger compensation coloring the background, you have to wonder what they were trying to do? Alienate their customers and dispose of what reputation that BA had left for attention to flight safety.
The FAA action was well warranted and the fine was a distinct undershoot.
