## Discrepancy

PASSING 18,000 AND AFTER SELECTING LANDING LIGHTS RECEIVED "RT AC BUS "OFF" EICAS.  AFTER QRH, WE COULD NOT RESTORE RT AC BUS AND ACCEPTED LANDING CLEARANCE DUE TO LAND AT NEAREST SUITABLE AIRCRAFT CONFIGURED WITHOUT PROBLEM AND LANDING ROLLOUT AND TAXI UNEVENTFUL.  RAN ENGINES TO TRY TO DUPLICATE THIS ISSUE.  DURING ENGINE RUN, NO FAULTS WERE FOUND.  PER FAULT TREE 24-20-801, WE DID A BITE TEST ON THE BPCU, NO FAULTS WERE FOUND.  A/C SYSTEM IS OPERATING NORMALLY.
