Good overall condition.  The front binder cover has a split on the hinge as you can see.  Pages intact and complete.  The first few pages loose but just need those little hole punch reinforcement stickers to secure to the binder again.  A few pages have highlights and markings here and there.   Pages are mostly clean & bright.  Last page of book has an envelope with a complete electrical wiring schematic diagrams for the aircraft that unfolds.
