H-25B CREW HAD A TRACK DEV DEPARTING RNO.

Narrative

ON MAY/FRI/01; ON PART 91 FRACTIONAL FLT; WE DEPARTED RENO/TAHOE INTL ARPT (CLASS C) ON FLT TO LIVERMORE; CA. I (PIC) COPIED OUR IFR ATC CLRNC FROM RNO CLRNC DELIVERY. MY READBACK WAS CORRECT. WE WERE ASSIGNED THE RENO DEP SID. THIS IS AN ESSENTIALLY STRAIGHT-OUT DEP TRACKING THE RNO LOC S FOR RADAR VECTORS ON-COURSE. ON DEP; ATC GAVE US A TURN EBOUND. I QUESTIONED WHAT THE TURN WAS FOR; AND ATC SAID 'FOR ON-COURSE.' AT THAT TIME ANOTHER CTLR ASKED US WHICH SID WE HAD BEEN GIVEN. I LOOKED AT MY NOTE PAD AND TOLD HIM THE RENO 2. I THEN LOOKED AT THE SID AND TO MY SURPRISE WAS THE MUSTANG DEP. THIS WAS THE SID ON THE OTHER SIDE OF THE SID PLATE. THE SID AT THE SAME DISTANCE (3 NM) CALLED FOR A L TURN TO THE FMG VOR. AT THIS POINT; WE HAD ALREADY TURNED L TOWARDS THE VOR WHEN WE SHOULD NOT HAVE. THE GRAPHIC PORTIONS AT A GLANCE WERE SIMILAR PLUS WE ONLY HAD 1 COPY OF THE SID. HAD EACH PLT HAD A COPY; THIS MIGHT NOT HAVE HAPPENED AS EASILY. SOMEHOW; I MUST HAVE TURNED THE PLATE OVER WHEN I DROPPED IT AS THE SIC WAS FLYING THE DEP.
