THE REPAIR WAS COMPLETED AT 1790.7 TTSN, IN 160.5 HOURS THE PROBLEM IS COMING BACK. MFG STATES THAT THIS IS NOT A STRUCTURAL PROBLEM, BUT THE REPAIR THEY RECOMMENDED DID NOT FIX THE PROBLEM. DUE TO THE CIRCUMSTANCES IT IS SUSPECTED TO HAVE STRUCTURAL PROBLEMS WITH THE RIVETS MOVING IN THE FUSELAGE.
