C172 starting a new log book for that reason is fine but just like the other reply said, keep all of them and keep them in good condition. i had to start a new logbook after only 30 hours since the binder gave out and was falling apart. if your just starting out try and keep your logbook very very very neat and error free. one way to impress someone in an interview is to have a nice, clean, neatly written kept up log book without errors. i had old instructors make alot of errors like putting flight time in the sim column, single time under multi-engine, etc.. i would make sure every entry is neat, legal and correct. i had to start watching my instructors when they put in the time to make sure it was correct..and use a black pen always, no pencil, markers or blue pen..do that and keep it the same through out and you will have a very presentable logbook an interviewer will be thankful to see!!!!!
