Sorry FlightDetent - I was simply referring to the hull loss and fatal hull loss accident rates. Nothing to do with engines specifically. Granted, a very simplistic argument - but if more engines made the aircraft safer, then one would expect that quads and tri's would have better accident rates than twins - and that's simply not the case.

Although shutdown and loss of control rates are tracked by operational hours and cycles, the fact remains that most engine failures occur early in the flight - takeoff and initial climb. Failures at cruise are but a small subset of the total numbers.
The loss of 50% thrust on a quad - particularly early in the flight - can be catastrophic - quads are not designed for that. In fact the most recent accident I can recall which was the result of multiple independent engine failures was a 747F. Specifically - roughly ten years ago - a Kalitta 747F suffered a major engine failure during takeoff (turbine failure) - the pilot apparently advanced the remaining engine throttles, which prompted a second engine to fail. They didn't make it.
