What was found
ALL 4 BOLTS HOLDING VERTICAL STABILIZER SPAR TO REAR BULKHEAD WERE LOOSE. I SAW BLACK ALUMINUM DUST AROUND THE LOWER TWO DURING A ROUTINE INSPECTION. I REMOVED THE BOLTS AND DID NOT FIND SIGNIFICANT WEAR ON THE STRUCTURES. THE NUTS HAD TORQUE STRIPE ON THEM, COVERED IN PAINT FROM THE FACTORY. I TESTED THE TORQUE ON THE TOP TWO BOLTS BEFORE I REMOVED THEM. THEY STARTED MOVING AT 30IN/LBS, THE TORQUE CALLED FOR IN THE AIRCRAFT MAINTENANCE MANUAL IS 100IN/LBS.
