Fatal accident rate single engined aeroplanes: 0.31 per 100,000 hours.
Fatal accident rate multi-engined aeroplanes: 0.98 per 100,000 hours.
(Note that a fatal accident for the purpose of the rate above is an accident in which there was at least one fatality. It does not reflect total people killed)
Total accident rates were similar at 9.54 per 100,000 hours for singles and 8.39 per 100,000 hours for multis. The difference is that accidents in multi-engined aeroplanes were around 3 times more likely to result in a fatality.
Total reported hours flown were 1,299,900 for singles, and 2,647,300 for multis.
historically in engine failure accidents you were more likely to be killed in a twin engine than single (maybe that has changed)
