## Discrepancy

(CAN) LEFT MLG TRUSS ANGLE NOTED TO HAVE CRACK APPROXIMATELY 0.7" LONG IN RADIUS. CRACK DISCOVERED BY VISUAL INSPECTION AND CONFIRMED USING FLPI.  THIS ANGLE PROVIDES SECONDARY ATTACHMENT OF THE MLG TRUSS FORGING TO THE LOWER WING SKIN.  CRACK WAS REPAIRED USING A NESTED STAINLESS STEEL DOUBLER SECURED WITH HILOKS AND RIVETS IAW DER PROVIDED DATA. THE RT MLG TRUSS ANGLE WAS REPAIRED ON THE SAME ACFT IN MARCH 2005.  APPARENTLY THIS IS A FAIRLY COMMON PROBLEM WITH THIS SERIES OF ACFT.  IT IS SPECULATED THAT THIS DEFECT COULD BE CAUSED BY REPEATED HARD LANDINGS AND/OR ROUGH FIELD OPERATIONS.
