C501 PLT HAD ALT OVERSHOOT IN IAD CLASS B AIRSPACE.

Narrative

THE ACFT (A CITATION 501) WAS FLOWN TO THE CLRNC ALT OF 4000 FT CALLED FOR BY THE CAPITOL 4 DEP PROC FOR IAD ARPT. UNFORTUNATELY; THIS PROC HAD RECENTLY BEEN REPLACED BY THE CAPITAL 5 PROC; WHICH CALLS FOR MAINTAINING 3000 FT. THE PLT HAD NOT NOTICED THE UPDATE IN THE COMMERCIAL IFR SID PLATE; NOR COMPARED THE PROC NAME ON THE DEP PLATE TO THAT SPECIFIED IN THE VERBAL CLRNC (IE; CARELESSNESS). THE ERROR WAS NOTICED BY THE DEP CTLR AFTER THE PLT ESTABLISHED INITIAL CONTACT. THE MISTAKE WAS IMMEDIATELY RECOGNIZED BY THE PLT; AND ACKNOWLEDGED; WITH AN APOLOGY. ONE CONTRIBUTING FACTOR WAS THE INABILITY TO MAKE INITIAL CONTACT WITH THE DEP CTLR; DUE TO THE CTLR'S LENGTHY CONVERSATION WITH ANOTHER ACFT WHICH WAS APPARENTLY LOST; OR IN A PLACE OTHER THAN THAT EXPECTED BY THE CTLR; AND COINCIDENTALLY THE ABILITY OF THE CITATION TO REACH THE INITIAL DEP ALT FASTER THAN NORMAL DUE TO LIGHT TKOF WT (10000 LBS). A CALL OF 'CLBING TO 4000 FT' MIGHT OTHERWISE HAVE BEEN CHALLENGED BY THE DEP CTLR BEFORE THE ACFT CLBED THROUGH THE 3000 FT LEVEL. SUGGESTION: THIS TYPE OF ERROR MIGHT BE DECREASED IF THE ENTIRE PROC NAME WAS CHANGED AT THE TIME OF ANY SIGNIFICANT CHANGE TO THE ACTUAL PROC (RATHER THAN JUST INCREMENTING THE PROC INDEX NUMBER; OR PERHAPS HAVE THE PROC RECEIVE A NEW NAME CONSISTING OF 5 RANDOMLY GENERATED LETTERS (EG; 'YLCRF') EACH TIME THE PROC IS CHANGED.
