Narrative:

I was captain, PNF. First officer landed ILS visual runway 19L at sfo. I took control of aircraft, exited runway at taxiway G and stopped. After waiting several seconds with no instructions from tower, I directed first officer to contact ground on 121.8 I had preselected. We told ground we had just cleared the runway, and controller answered quote, 'taxi to the ramp.' I taxied straight ahead and turned right onto taxiway a, proceeding to the ramp. As I taxied onto taxiway a, it occurred to me that I had landed on runway 19L, and would have crossed runway 19R to reach the inner. We had just crossed the runway without a specific clearance to cross from either tower or ground controller. I noted that no amber hold lights or white runway lights appeared to be illuminated on runway 19R. ATIS that hour did not list runway 19R as an active runway. I did not see any aircraft in position on takeoff roll or short final for either runway 19L or runway 19R. I do not believe any loss of separation occurred, however, how easily this incursion could occur has my attention. Some contributing factors include narrow spacing of the 2 runways, nearby ramp lights much brighter than taxi and runway lights, cleanup checklist items as we exit runways, and inadequate airport diagram review at familiar airports.

Title: A POSSIBLE RWY INCURSION DURING A NIGHT OP AS RPTED BY A S80 PIC AFTER LNDG RWY 19L AT SFO, CA.

Narrative: I WAS CAPT, PNF. FO LANDED ILS VISUAL RWY 19L AT SFO. I TOOK CTL OF ACFT, EXITED RWY AT TXWY G AND STOPPED. AFTER WAITING SEVERAL SECONDS WITH NO INSTRUCTIONS FROM TWR, I DIRECTED FO TO CONTACT GND ON 121.8 I HAD PRESELECTED. WE TOLD GND WE HAD JUST CLRED THE RWY, AND CTLR ANSWERED QUOTE, 'TAXI TO THE RAMP.' I TAXIED STRAIGHT AHEAD AND TURNED R ONTO TXWY A, PROCEEDING TO THE RAMP. AS I TAXIED ONTO TXWY A, IT OCCURRED TO ME THAT I HAD LANDED ON RWY 19L, AND WOULD HAVE CROSSED RWY 19R TO REACH THE INNER. WE HAD JUST CROSSED THE RWY WITHOUT A SPECIFIC CLRNC TO CROSS FROM EITHER TWR OR GND CTLR. I NOTED THAT NO AMBER HOLD LIGHTS OR WHITE RWY LIGHTS APPEARED TO BE ILLUMINATED ON RWY 19R. ATIS THAT HR DID NOT LIST RWY 19R AS AN ACTIVE RWY. I DID NOT SEE ANY ACFT IN POS ON TKOF ROLL OR SHORT FINAL FOR EITHER RWY 19L OR RWY 19R. I DO NOT BELIEVE ANY LOSS OF SEPARATION OCCURRED, HOWEVER, HOW EASILY THIS INCURSION COULD OCCUR HAS MY ATTN. SOME CONTRIBUTING FACTORS INCLUDE NARROW SPACING OF THE 2 RWYS, NEARBY RAMP LIGHTS MUCH BRIGHTER THAN TAXI AND RWY LIGHTS, CLEANUP CHKLIST ITEMS AS WE EXIT RWYS, AND INADEQUATE ARPT DIAGRAM REVIEW AT FAMILIAR ARPTS.
