## Discrepancy

WITH VENTRAL AIR STAIR EXTENDED, BOTH LT AND RT HANDRAIL AFT VERTICAL TUBES ARE CORRODED-RUSTED AT THEIR LOWER END.  CORROSION CAN BE SEEN AS A RING OF RUST POWDER AROUND THE JUNCTION OF THE TUBE INTO THE FITTING ASSEMBLY SUPPORT (P/N 39366673-501 OR -502).  RETAINING BOLT HAS TO BE REMOVE AND THE TUBE PULLED FROM THE FITTING ASSEMBLY SUPPORT FOR A PROPER EVALUATION OF THE TUBE CONDITION.  THESE ARE BELIEVED TO BE THE ORIGINAL TUBES.
