## Discrepancy

RIB IS BROKEN. THE LEAD TIP WEIGHT THAT IS BOLTED TO THE OUTBOARD RIB (APPROXIMATELY 4 POUNDS), WAS FOUND RATTLING AROUND IN THE LEFT HORIZONTAL STABILIZER TIP CAP.  FURTHER INVESTIGATION REVEALED THE TIP WEIGHT, WHICH IS SECURED TO THE OUTBOARD RIB WITH BOLTS AND ALUMINUM RIVNUTS, PULLED THE RIVNUTS OUT OF THE RIB.
