Over thirty five years of flying single and twins I only had one engine failure in a single and none in a twin
I lost three engines in my 30 years of flying twins. None flying singles
Funny the diverse range of experiences. Personally never had a failure in a single, for which I'm thankful having spent many an hour over water with a single T-53 in all sorts of weather, including IMC at 500', at times looking down through the chin bubble at the wind driven spume and praying to Mr. Lycoming, because failure on his part would have meant death on our part. Twin? Two blow em up failures, same aircraft, first #2, then #1 a couple of years later. Hate Turbomeca as a result. Early Allison days provided a lot of opportunity to practise single engine due chip lights.
