Enroute to BFI; we were instructed to descend via the JAWBN 3 Arrival. We misread the restriction at JAWBN. The chart is misleading. The restriction box calls out landing north or south in reference to SEA. Below that it calls out 'BOEING FIELD/KING COUNTY RWY 13.' We read that as Boeing Field (all runways) or King County Runway 13. The Controller pointed out the deviation and instructed us to cross ALKIA at 12;000 feet. We did so. When we reached BFI we checked the NOS chart and realized our mistake.Change the chart to match the NOS chart which would eliminate the confusion.
A CE-560XL flight crew inbound to BFI on the JAWBN RNAV STAR misread the intent of the crossing restriction at JAWBN. The reporter believes the format of the commercially produced chart restriction 'LANDING BOEING FLD/KING CO RWY 13...Cross at and MAINTAIN 11000' was a contributing factor.
