While not holding out much hope for change, I must admit to being disappointed that an aircraft like the Stinson 108, renowned for its stability, light control forces, and ease of use on instruments, is restricted to day VFR ops. That is just one example, but there are many types previously certified, but no longer directly supported my their manufacturers, which are now operating on permits. While I can maybe see merit in the argument that non-certified types MAY constitute risk, I do not see how 'orphaned' previously certified typed do, assuming of course that this is the case, what with me being in Australia and a bit 'out of the loop'.
