Narrative:
On my first trip after IOE, I was PF into lax. Approach control kept us high on the approach and when cleared to lower altitude I slowed to approximately 190 KTS to descend faster with flaps. I was unaware that we had been assigned 250 KTS. It was my captain's 3RD trip after IOE which he finished approximately 6 weeks ago. Once again, 2 inexperienced (in aircraft type) pilots shouldn't have been assigned to fly together.

Narrative: ON MY FIRST TRIP AFTER IOE, I WAS PF INTO LAX. APCH CTL KEPT US HIGH ON THE APCH AND WHEN CLRED TO LOWER ALT I SLOWED TO APPROX 190 KTS TO DSND FASTER WITH FLAPS. I WAS UNAWARE THAT WE HAD BEEN ASSIGNED 250 KTS. IT WAS MY CAPT'S 3RD TRIP AFTER IOE WHICH HE FINISHED APPROX 6 WKS AGO. ONCE AGAIN, 2 INEXPERIENCED (IN ACFT TYPE) PLTS SHOULDN'T HAVE BEEN ASSIGNED TO FLY TOGETHER.
