About 40 mi nne of acy (my destination airport) I was cleared to descend from 6000 ft MSL to 4000 ft MSL. I was also told to expect landing on runway 13 with a left base entry. I mistook this to mean that I should descend for landing and continued my descent to 3400 ft. At this time the controller requested my altitude and cleared me to descend to 3000 ft. There was no other traffic in the area at this time to conflict with.

Narrative: ABOUT 40 MI NNE OF ACY (MY DEST ARPT) I WAS CLRED TO DSND FROM 6000 FT MSL TO 4000 FT MSL. I WAS ALSO TOLD TO EXPECT LNDG ON RWY 13 WITH A L BASE ENTRY. I MISTOOK THIS TO MEAN THAT I SHOULD DSND FOR LNDG AND CONTINUED MY DSCNT TO 3400 FT. AT THIS TIME THE CTLR REQUESTED MY ALT AND CLRED ME TO DSND TO 3000 FT.
