## Discrepancy

(CAN) DURING THE INSTALLATION OF A LANDING GEAR SB (SB45-32-29R1) IT WAS REQUESTED THAT INSP OF THE INTERNAL SURFACES OF THE LANDING GEAR AXLE BEAM ASSY FOR POSSIBLE CORROSION.  BOROSCOPE INSPECTIONS COMPLETED, CORROSION IDENTIFIED AND MFG CONTACT WITH THE RESULTS OF THE DISCOVERY. MFG ENGINEERING REQUESTED AXLE BEAMS BE REMOVED FOR REPAIR.  LOANER AXLE BEAMS INSTALLED AND GEAR SWINGS COMPLETED WITHOUT INCIDENT.  THIS IS A COMMON PROBLEM WITH THE LWR AXLE BEAM ASSEMBLIES AND INCORPORATION OF THE ABOVE MENTIONED SB IS THE SUGGESTED REPAIR.
