## Discrepancy

WHEN THE LEFT HORIZONTAL STABILIZER WAS REMOVED FOR ELECTRICAL TROUBLESHOOTING, 7 CRACKS IN THE SHEET METAL WERE FOUND ON THE INBD RIB AND FORE AND AFT SPARS WHERE THEY ATTACH TO THE INBD RIB.  CRACKS CANNOT BE SEEN WITH THE STABILIZER INSTALLED.  A TORQUE TUBE PASSES THROUGH THE TAILBOOM AND APPROXIMATELY HALF WAY OTBD THROUGH THE STABILIZER. THIS TUBE CARRIES MOST OF THE IN-FLIGHT LOAD.  IT IS ATTACHED TO THE INBD RIB OF THE STABILIZER WITH 4 BOLTS TO THE STABILIZER AND A CLAMP TO THE TUBE.  THE RT STABILIZER WAS REMOVED AND INSPECTED AND NO CRACKS WERE FOUND.
