Sorry, I read the UK CAA reports & MORs - have I missed a load of failures in the donkey dept of SEHs ?
I see a lot of chip lights, hydraulics and other bits failing in twins - which leads to a forced landing and the inevitable report - but I see far great reliability and less stress in SEH.
Insurance companies would prefer that we all stay on the ground in a cottonball and never go anywhere - hence some of the ridiculous "keyman" requirements which sometimes include mandatory multi-engines for any flying.
As ever, it's a way to ramp the premium by creating a risk far greater than it really is.
