The Turkish (THY) DC-10 in Paris was not so lucky, as the issue led to a catastrophic structural failure, inflight loss of control and death of 300+ pax and crew. At the time the worst air disaster ever.
Another DC-10 design flaw was the positioning of all three hydraulic lines side-by-side-by-side in the empennage, which led to a total loss of control in UA232 following an uncontained turbine disk failure in the #2 (tail) engine.
No events where DC-10 engines simply “fell off”, to my knowledge, aside from AA191, which was indeed a result of a sloppy engine change practice using a forklift.
It's been interesting seeing the discussion of AA191 -- but not for the fact that an AA agent moved them up to the next earlier flight after they showed up at ORD a little early that day, my (at that time 3-yr old) wife and her family would have been onboard that day. Scary to think about what could have been, but very reassuring to know that the lessons learned from these events have led to the excellent safety record of modern-day U.S. aircraft.
