## Discrepancy

PILOT REPORTED UNSAFE NLG ON FINAL. CYCLED AND INDICATION WAS SAFE. JACKED AC, RAN GEAR THROUGH RIG AND OPS CK. FOUND NLG DOWN LIMIT SWITCH WOULD NOT ACTIVATE PUMP IF IT WAS NOT DOWN AND LOCKED. REPLACED SWITCH AND OPS CK SYSTEM THROUGH 5 NORMAL AND 3 EMERGENCY CYCLES. AC RETURNED TO SERVICE. BENCH CHECK OF SWITCH REVEALED OPEN CONDITION WHEN IT SHOULD BE CLOSED.
