The Bae 146 answer
For some years I flew the Bae 146 (Jumbolino) A strange little beast- a single engine failure didn't even require a different checklist! AND the range suddenly increased significantly. A double engine failure was a more serious situation and did happen on a few occasions, although not to me fortunately. The biggest problem with the little ALF502 engines was that they failed rather more frequently than the industry norms of the time. (Give me a B737 NG any day even if it only has two engines- but then the CFM56 is about the most reliable engine ever built!)
