A Tristar back in the eigthies lost all three engines, two were lost, the last (number 2) only made it (to landing, and then failed) because it had been shut down during flight. Cause: During overnight maintinance a mixup had occured and the rubber O-rings on the chip-detectors was missing. During flight the oil leaked from all engines. The number 2 came on first with low oil qty warning, and was shut down. Crew decided to return to Miami, and on return the other two low oil qty came on. Crew belived it was a false indication (what are the ods of all three engines missing oil...???) So shortly after the number 1 and 3 engine failed. Over a period of time the L1011 was a big glider. The crew started the number 2 engine, and flew on that single engine into Miami and made a safe landing. After landing as the aircraft was to leave the rwy, the number 2 engine allso failed.
