## Discrepancy

AIRCRAFT WAS GROUNDED: AFT RIGHT WING FUEL LOW PRESSURE LIGHT DOES NOT ILLUMINATE WHEN THE FUEL PUMP  SWITCH IS TURNED OFF. REMOVED AND REPLACED RIGHT AFT FUEL BOOST PUMP PRESSURE SWITCH, IAW AMM 28-42-11. PRESSURE SWITCH OPS CHECK NORMAL LIGHT EXTINGUISHES AND ILLUMINATES AS INTENDED.
