## Discrepancy

WING/FUSELAGE REAR SPAR CONNECTION HAS IMPROPER BOLTS INSTALLED FROM THE MFG.  NOTICED FUEL LEAK FROM AROUND BOLTS AND CONFIRMED FROM THE MFG THAT IMPROPER BOLTS WHERE INSTALLED IAW THE DESIGN DRAWINGS.  THE BOLTS INSTALLED WHERE A D23 AND SHOULD HAVE BEEN A D21.  AS A RESULT OF THE 3.2MM LONGER BOLTS, THEY WHERE UNABLE TO BE TORQUED DOWN PROPERLY ALLOWING MOVEMENT OF THE BOLTS, BELIEVE THIS TO BE THE CAUSE OF THE FUEL LEAKING AROUND THE BOLTS.
