CAAP 5.23-1 (1) is a great publication. All M/E Instructors should read this thoroughly and then read it twice more. The biggest problem I think is ineperience and complacency. Gee I always demonstrated and observed full feathered landings. Remember you ,the instructor, knows this (the m/e trainer) aircraft like the back of your hand. Yep, sure many times there were "goof" ups but nothing you wern't expecting nor could get out of.
