Narrative:

I received our clearance from ftw clearance delivery. It was to maintain runway heading vectors for the dallas 8 departure; maintain 3000 ft; expect FL390 in 10 mins; contact departure on 135.97; squawk XXXX. My readback was confirmed. I got out the dallas 8 departure and set our squawk and departure frequency. At that time our passenger began to arrive and I loaded their luggage. I returned to the cockpit and read the dallas 8 SID. It said to maintain 10000 ft unless otherwise assigned. I set 10000 ft in the altitude selector. When the captain arrived; I briefed him on the departure. I said runway heading for vectors to the dallas 8; maintain 10000 ft. During taxi out; I saw that the departure frequency was not the frequency depicted on the SID and without checking our clearance I put the SID frequency in communication #2 for departure. After takeoff; I contacted departure stating out of 2000 ft climbing to 10000 ft. I was instructed to contact departure on a different frequency. I checked in out of 3000 ft climbing to 10000 ft. We were instructed to maintain 8000 ft. Later we were talking with ZFW. We were told of a possible deviation and given a phone number to call. We looked at our clearance and discovered my error. This deviation was completely my fault. I did not follow my own technique during taxi out to doublechk departure frequency; altitude and squawk. My changing departure frequency compounded the situation. The correct controller would have noted my 10000 ft climb and corrected us to maintain 3000 ft. I have over 21000 hours and until now never had an altitude deviation. From now on; I will strictly adhere to my technique to confirm altitude; frequency and squawk to prevent any further deviations.

Title: G200 FLT CREW REPORTS ALTITUDE DEV DEPARTING FTW DUE TO RELIANCE ON SID VERBIAGE RATHER THAN THE ACTUAL CLEARANCE AS RECEIVED.

Narrative: I RECEIVED OUR CLRNC FROM FTW CLRNC DELIVERY. IT WAS TO MAINTAIN RWY HDG VECTORS FOR THE DALLAS 8 DEP; MAINTAIN 3000 FT; EXPECT FL390 IN 10 MINS; CONTACT DEP ON 135.97; SQUAWK XXXX. MY READBACK WAS CONFIRMED. I GOT OUT THE DALLAS 8 DEP AND SET OUR SQUAWK AND DEP FREQ. AT THAT TIME OUR PAX BEGAN TO ARRIVE AND I LOADED THEIR LUGGAGE. I RETURNED TO THE COCKPIT AND READ THE DALLAS 8 SID. IT SAID TO MAINTAIN 10000 FT UNLESS OTHERWISE ASSIGNED. I SET 10000 FT IN THE ALT SELECTOR. WHEN THE CAPT ARRIVED; I BRIEFED HIM ON THE DEP. I SAID RWY HDG FOR VECTORS TO THE DALLAS 8; MAINTAIN 10000 FT. DURING TAXI OUT; I SAW THAT THE DEP FREQ WAS NOT THE FREQ DEPICTED ON THE SID AND WITHOUT CHKING OUR CLRNC I PUT THE SID FREQ IN COM #2 FOR DEP. AFTER TKOF; I CONTACTED DEP STATING OUT OF 2000 FT CLBING TO 10000 FT. I WAS INSTRUCTED TO CONTACT DEP ON A DIFFERENT FREQ. I CHKED IN OUT OF 3000 FT CLBING TO 10000 FT. WE WERE INSTRUCTED TO MAINTAIN 8000 FT. LATER WE WERE TALKING WITH ZFW. WE WERE TOLD OF A POSSIBLE DEV AND GIVEN A PHONE NUMBER TO CALL. WE LOOKED AT OUR CLRNC AND DISCOVERED MY ERROR. THIS DEV WAS COMPLETELY MY FAULT. I DID NOT FOLLOW MY OWN TECHNIQUE DURING TAXI OUT TO DOUBLECHK DEP FREQ; ALT AND SQUAWK. MY CHANGING DEP FREQ COMPOUNDED THE SITUATION. THE CORRECT CTLR WOULD HAVE NOTED MY 10000 FT CLB AND CORRECTED US TO MAINTAIN 3000 FT. I HAVE OVER 21000 HRS AND UNTIL NOW NEVER HAD AN ALTDEV. FROM NOW ON; I WILL STRICTLY ADHERE TO MY TECHNIQUE TO CONFIRM ALT; FREQ AND SQUAWK TO PREVENT ANY FURTHER DEVS.
