Well I really have myself in a situation. I am still a low time pilot (450TT) and I got hired on by a small company that has a flight school and small 135 operation. Where I have screwed up is that in my origianal logbook I have incorectly logged some King Air 90 time as PIC. The guy I work for is old and not worried at all about logging time and he lets me fly the plane. The only time he flies is during take off, landing, and taxi whenever there is freight or people on the plane. I was aware of the reg that being the sole manipulator of the contorls you can log pic but didn't realize that it was only for pt 91 nor did I until recently realized that it was illegal for me to handle the controls during 135 flights as I have not taken a 135 checkride. So now I am trying to figure out what I can do to straighten this out in my log book as only about 1/3 of the time I logged I can actually log. As I read in here it is kind of important to have my first log book with all endorsements and signatures but seems it would be really sketchy haveing a whole bunch of flight crossed out. It is about 45hr of logged time that I am dealing with here. Thanks for the help I am really stressed over the situation.
