Narrative:

Cpr X departing stl in turbo commander 1000 (AC695A) received cards 3 departure with assigned altitude of 5000 ft. Departure reads for propeller aircraft 3000 ft or assigned altitude. Assumed clearance delivery knew what they were doing. Departure was expecting climb to 3000 ft. Had B727 ahead and left climbing to 5000 ft being vectored across our flight path. Departure saw upcoming conflict, stopped my climb at 4500 ft and issued 60 degree r-hand turn. VFR separation was maintained. Problem seems to be in aircraft type identify. A turbo commander 1000 is listed as AC95, but many controllers seem to think this is a jet commander 1121. Proper identify is important. Need to issue clarification of type idents. I suspect many pilots are not using this type identify. AC69 = jetprop commander, AC6T = 690C commander, AC84 = jet commander 840/980/1000, AC95 = 695 commander, (either of these idents are applicable to my aircraft).

Original NASA ASRS Text

Title: CPR X ASSIGNED WRONG ALT FOR PROP ACFT HAD LTSS FROM B727. SYS ERROR.

Narrative: CPR X DEPARTING STL IN TURBO COMMANDER 1000 (AC695A) RECEIVED CARDS 3 DEP WITH ASSIGNED ALT OF 5000 FT. DEP READS FOR PROPELLER ACFT 3000 FT OR ASSIGNED ALT. ASSUMED CLRNC DELIVERY KNEW WHAT THEY WERE DOING. DEP WAS EXPECTING CLB TO 3000 FT. HAD B727 AHEAD AND L CLBING TO 5000 FT BEING VECTORED ACROSS OUR FLT PATH. DEP SAW UPCOMING CONFLICT, STOPPED MY CLB AT 4500 FT AND ISSUED 60 DEG R-HAND TURN. VFR SEPARATION WAS MAINTAINED. PROB SEEMS TO BE IN ACFT TYPE IDENT. A TURBO COMMANDER 1000 IS LISTED AS AC95, BUT MANY CTLRS SEEM TO THINK THIS IS A JET COMMANDER 1121. PROPER IDENT IS IMPORTANT. NEED TO ISSUE CLARIFICATION OF TYPE IDENTS. I SUSPECT MANY PLTS ARE NOT USING THIS TYPE IDENT. AC69 = JETPROP COMMANDER, AC6T = 690C COMMANDER, AC84 = JET COMMANDER 840/980/1000, AC95 = 695 COMMANDER, (EITHER OF THESE IDENTS ARE APPLICABLE TO MY ACFT).
