Pre-Flight Tip
Just because you fly club aircraft that get a daily inspection by Superman Flying Instructors (sometimes including ex-forces Deities) and then pre-flighted 6 times a day . . . don't imagine they're free of mundane defects.
viz. On pre-flighting my favourite PA28 which I hadn't flown since its re-spray, imagine my surprise on finding both fuel vents blocked by paint. Just waiting for the seals on the filler caps to be renewed at the next annual. (The re-spray was nine months old.)
Also, don't assume that the defect you've just spotted has been seen, logged and accepted as OK to fly. Get someone with real experience to come and look at it. Because EITHER you will save yourself from an unsafe aeroplane OR you will learn a little bit more about that fine line between normal and abnormal.
