## Discrepancy

DURING ANNUAL INSPECTION AND GEAR SADDLE INSPECTION PER AD 76-14-7R2, THE OUTBOARD LT TUNNEL ASSEMBLY WAS FOUND CRACKED OUT FROM AN INSPECTION HOLE TO THE OUTER SKIN.  THE CRACK STARTED JUST AFT OF A FACTORY INSTALLED DOUBLER PLATE.  THE GEAR SADDLE ON THIS SIDE WAS ALSO FOUND TO HAVE A CRACK, REPLACEMENT OF BOTH PANEL AND SADDLE WERE ACCOMPLISHED.  SUBMITTER STATED CAREFUL INSPECTION AT ANNUAL OR 100-HOUR INTERVALS WOULD DETECT THIS TYPE CRACK BELIEVED TO BE CAUSED BY A HARD L ANDING.  NO DAMAGE NOTED ON RT SIDE.  EXTENSION OF THE DOUBLER WOULD POSSIBLY ELIMINATE THE STRESS CONCENTRATION IN THIS AREA.
