Yes you are correct....CFIT is the main culprit.......then collisions and then component failures [From memory I think thats about correct.......], and a bunch full of engines would'nt help you there......
But Hey........I have had two engine failures....one in a PT6 as a result of Turbine Rub and the other in a 1S1 with a bearing failure........and guess what, the second engine was real handy.
The laws of average were against me I guess.........singles are something I reflect back on.........shows I am getting Old!!
