The Boeing 767, carrying 9 crew members and 226 passengers, was on its way to Atlanta. Pilots had to turn around due to a problem with the left engine.
the responsibility for maintenance of the engines falls on the airline. occasionally you do get defective parts which are on the manufacturer, such as the Rolls Royce Trent 1000s which had issues with the intermediate pressure (IP) turbine blades being more susceptible to fatigue cracking related to corrosion. that was on Rolls Royce
And then there’s all the airlines getting their spares at the flea market (sometimes unwillingly) so there’s always the possibility of a surprise that way as well.
