How to Preflight a Cessna 172

Before you fly you must do the visual inspection required before all flights to ensure that the airplane is safe for flying. There's actually more to it than meets the eye. Some pilots have gotten lazy over the years and either neglect this simple task just to save 10 minutes or have done such a cursory review that it was a waste of effort. Some have lived to tell the tale.
