What was found
AFTER USING AN ORBITAL WAXING BUFFER ON THE HORIZONTAL STABILIZER, THE OWNER NOTICED LOOSENESS AT THE HORIZONTAL STABILIZER LEADING EDGE AND THE OUTBOARD EDGE. INVESTIGATION REVEALED THAT BOTH FOWARD ATTACH BOLTS, P/N AN44-5A (IPC FIG 18A ITEM 1) WERE LOOSE. BOLTS WERE RETORQUED PER MAINTENANCE MANUAL. THE VIBRATION ACTION OF THE BUFFER APPEARENTLY CAUSED THE LOOSENESS.
