Narrative:

While departing runway 29 at koak, we were given the oakland 5 departure. The SID states to cross 4 NM northwest at or below 2000 ft. I misread the SID as to cross 4 NM northwest at or above 2000 ft. The first officer was flying the aircraft. The first officer and I had been briefing the SID when we were interrupted by our passenger's early arrival. After receiving the passenger, we started engines and commenced taxiing. It is our procedure to read aloud the SID one last time prior to taking the runway. I was in the process of doing this when tower cleared us for takeoff with another aircraft on final. I hurriedly set 10000 ft in the altitude alerter (which was our clearance altitude) and stated that we were to cross 4 NM at or above 2000 ft. Neither of us caught these mistakes. We were climbing through 3500 ft before we realized the situation. Luckily, no other aircraft was involved with our altitude deviation. I feel that this event was caused by our passenger's arrival interruption, which threw us slightly out of sync, and our haste to accept takeoff clearance. Even though both of us know better than to allow this to happen, it proves that all checklists and procedures should never be rushed, no matter what the reason. Supplemental information from acn 516900: it was read to me as maintain 2000 ft or higher at 4.0 DME. After we were airborne, ATC advised us that the SID was for 2000 ft or below, until 4.0 DME. Our improper briefing of the SID, created the altitude infraction.

Title: G-IV DEP FROM OAK FAILS TO COMPLY WITH SID ALT RESTR.

Narrative: WHILE DEPARTING RWY 29 AT KOAK, WE WERE GIVEN THE OAKLAND 5 DEP. THE SID STATES TO CROSS 4 NM NW AT OR BELOW 2000 FT. I MISREAD THE SID AS TO CROSS 4 NM NW AT OR ABOVE 2000 FT. THE FO WAS FLYING THE ACFT. THE FO AND I HAD BEEN BRIEFING THE SID WHEN WE WERE INTERRUPTED BY OUR PAX'S EARLY ARR. AFTER RECEIVING THE PAX, WE STARTED ENGS AND COMMENCED TAXIING. IT IS OUR PROC TO READ ALOUD THE SID ONE LAST TIME PRIOR TO TAKING THE RWY. I WAS IN THE PROCESS OF DOING THIS WHEN TWR CLRED US FOR TKOF WITH ANOTHER ACFT ON FINAL. I HURRIEDLY SET 10000 FT IN THE ALT ALERTER (WHICH WAS OUR CLRNC ALT) AND STATED THAT WE WERE TO CROSS 4 NM AT OR ABOVE 2000 FT. NEITHER OF US CAUGHT THESE MISTAKES. WE WERE CLBING THROUGH 3500 FT BEFORE WE REALIZED THE SIT. LUCKILY, NO OTHER ACFT WAS INVOLVED WITH OUR ALTDEV. I FEEL THAT THIS EVENT WAS CAUSED BY OUR PAX'S ARR INTERRUPTION, WHICH THREW US SLIGHTLY OUT OF SYNC, AND OUR HASTE TO ACCEPT TKOF CLRNC. EVEN THOUGH BOTH OF US KNOW BETTER THAN TO ALLOW THIS TO HAPPEN, IT PROVES THAT ALL CHKLISTS AND PROCS SHOULD NEVER BE RUSHED, NO MATTER WHAT THE REASON. SUPPLEMENTAL INFO FROM ACN 516900: IT WAS READ TO ME AS MAINTAIN 2000 FT OR HIGHER AT 4.0 DME. AFTER WE WERE AIRBORNE, ATC ADVISED US THAT THE SID WAS FOR 2000 FT OR BELOW, UNTIL 4.0 DME. OUR IMPROPER BRIEFING OF THE SID, CREATED THE ALT INFRACTION.
