Narrative:
Assigned altitude of 8000' by monterey approach control. I was preoccupied with looking for the airport. My first officer was flying. He too became occupied looking for the airport and descended to 7700'. We quickly climbed back to 8000' and continued the flight. We were at 7700' for no more than a second. At approximately 10 mi final at 4600 we came very close (400') to another aircraft, an small aircraft. We were given traffic reports concerning this aircraft however by the time we saw it we had to make a hard right turn in order to avoid it.

Narrative: ASSIGNED ALT OF 8000' BY MONTEREY APCH CTL. I WAS PREOCCUPIED WITH LOOKING FOR THE ARPT. MY F/O WAS FLYING. HE TOO BECAME OCCUPIED LOOKING FOR THE ARPT AND DSNDED TO 7700'. WE QUICKLY CLBED BACK TO 8000' AND CONTINUED THE FLT. WE WERE AT 7700' FOR NO MORE THAN A SECOND. AT APPROX 10 MI FINAL AT 4600 WE CAME VERY CLOSE (400') TO ANOTHER ACFT, AN SMA. WE WERE GIVEN TFC RPTS CONCERNING THIS ACFT HOWEVER BY THE TIME WE SAW IT WE HAD TO MAKE A HARD R TURN IN ORDER TO AVOID IT.
