Someone loaned me a Rolls once to pick up a date. The exhaust system fell off on the way to the restaurant, clanging and banging on the street as we pulled up to the door. We were the laughing stock of the staff and onlookers - and a volunteer fixed the fallen muffler with a coat hanger. So much for nominal quality. I'd have been happier in a Chevy.
I may not be a massive fan of RR. However, imho, your viewpoint is too narrow.
I have absolutely no doubt that the problem you experienced was, inept maintenance; or possibly accident damage, not
any design or material fault of the original unit/s.
Not tottaly relative... but, I don't know how many Chev engines are in aircraft, but RR have
been supplying aircraft power plants for more than a hundred years. Even QANTAS
use RR engines.
Sympatico to your post, a QANTAS A380 had a catastrophic engine failure in flight. The power plant
was a Rolls Royce Trent engine. The turbine became unfastened to its shaft. As it freewheeled and no longer powered
the compressor stages, it over revved nine point nineskavitch, and centrifuged itself into titanium shrapnel.
The pieces of shrapnel took out part of the wing, the fuel system and a fuel tank fire started. Other shrapnel disabled one hydraulic system and the brakes. The control system for the undamaged #1 engine was also taken out as well as making the landing flaps inoperative... BAD ROLLS ROYCE!
The precipitous cause was a very small piece of pipe that carries oil to the shaft bearing adjacent to the turbine that failed.
The pipe appears to me to have been cocked at an angle to the fitting it "telescopes" onto when its fastening collar was tightened
causing it to crack and brake... Just my humble opinion.
