What was found
LIFT LINK FITTING AFT LUG FOUND CRACKED BY MECHANIC DURING DAILY INSP. CAUSE WAS FOUND TO BE WRONG P/N BOLT INSTALLED. TB 212-91-132 HAD BEEN COMPLETED WHICH INCORPORATES IMPROVED LIFT LINK FITTING P/N 212-030-154-101 THAT REQUIRES LARGER DIAMETER BOLT P/N 412-030-224-101. P/N 212-030-155-001 BOLT WAS FOUND INSTALLED. THIS BOLT IS .050" SMALLER DIAMETER THAN THE IMPROVED BOLT AND WOULD HAVE PERMITTED MOVEMENT WITHIN THE INSTALLED BUSHING. THIS SMALLER BOLT IS ALSO NORMALLY INSTALLED WITH THE HEAD FACING AFT WHILE THE NEW INSTALLATION IS WITH THE HEAD FORWARD. ANOTHER VISIBLE DIFFERENCE IS THE ORIGINAL BOLTS HAVE A FLAT SURFACE HEAD WHILE THE IMPROVED BOLTS HAVE A DIMPLED HEAD SURFACE.
