## Discrepancy

5 MINUTES PRIOR TO DESCENT, PILOT HEARD A "POOF" SOUND FOLLOWED BY A BURNED ODOR.  NR1 STICK PUSHER AND PUSHER FAIL CAUTION LIGHTS CAME ON FOR 3-5 SEC THEN GOES OUT. ALL SYSTEMS WERE FUNCTIONNAL. PILOT AND CO-PILOT VERIFIED COCKPIT AND ENTRANCE AREA BUT DIDN`T FIND ANYTHING.  F/A ADVISED BUT DIDN`T SEE ANYTHING EITHER.  DESCENT WAS DONE AND FLIGHT CREW CALL MAINTENANCE PERSONNEL AFTER A NORMAL LANDING WITH NO PROBLEM AND ALL SYSTEM FUNCTIONNING.
