## Discrepancy

MAIN GEAR BOX WAS BEING REMOVED FOR INPUT FREEWHEEL REPLACEMENT.  A CRACK WAS DETECTED ON THE RT FOOT OF REAR COVER, AS WELL AS A CRACK ON THE RT REAR AIRFRAME FITTING.  THE  ALIGNMENT FIXTURE WAS USED TO CHECK THE BOX BEAM, AND FOUND TO BE MISALIGNED.  THE RT REAR AND LT FRONT FITTINGS WERE REPLACED TO CORRECT ALIGNMENT, AND GEAR BOX WAS REPAIRED AND REINSTALLED.
