Narrative:

I was issued clearance on the ground, 'cleared as filed to osu, maintain 2000 ft, expect 9000 ft, 10 mins after departure. Contact departure on 119.1.' I copied this down, then when ready for takeoff I called again for sequencing. (There is no tower at awm but clrncs are obtained on the ground.) I was told: 'you are released, fly runway heading, maintain 2000 ft.' I did not write that down. I was rolling toward the runway, clearing traffic and switching to the CTAF. After departure, I flew runway heading and tried to contact departure -- the frequency was quite congested. My course was nearly 180 degrees opposite the runway heading. I glanced down at my written clearance and almost without thinking began a left turn toward my course. Then I was finally able to get through to departure control and was told to immediately turn back to runway heading. Of course this was my mistake. I had a mental lapse. I should have written down my second clearance. I will in the future write down everything.

Original NASA ASRS Text

Title: PLT OF AN SMT INADVERTENTLY ENTERED CLASS B AIRSPACE WHEN HE TURNED FROM RWY HEADING ON AN IFR DEP FROM A NON TWR ARPT WITHOUT CLRNC.

Narrative: I WAS ISSUED CLRNC ON THE GND, 'CLRED AS FILED TO OSU, MAINTAIN 2000 FT, EXPECT 9000 FT, 10 MINS AFTER DEP. CONTACT DEP ON 119.1.' I COPIED THIS DOWN, THEN WHEN READY FOR TKOF I CALLED AGAIN FOR SEQUENCING. (THERE IS NO TWR AT AWM BUT CLRNCS ARE OBTAINED ON THE GND.) I WAS TOLD: 'YOU ARE RELEASED, FLY RWY HEADING, MAINTAIN 2000 FT.' I DID NOT WRITE THAT DOWN. I WAS ROLLING TOWARD THE RWY, CLRING TFC AND SWITCHING TO THE CTAF. AFTER DEP, I FLEW RWY HEADING AND TRIED TO CONTACT DEP -- THE FREQ WAS QUITE CONGESTED. MY COURSE WAS NEARLY 180 DEGS OPPOSITE THE RWY HDG. I GLANCED DOWN AT MY WRITTEN CLRNC AND ALMOST WITHOUT THINKING BEGAN A L TURN TOWARD MY COURSE. THEN I WAS FINALLY ABLE TO GET THROUGH TO DEP CTL AND WAS TOLD TO IMMEDIATELY TURN BACK TO RWY HEADING. OF COURSE THIS WAS MY MISTAKE. I HAD A MENTAL LAPSE. I SHOULD HAVE WRITTEN DOWN MY SECOND CLRNC. I WILL IN THE FUTURE WRITE DOWN EVERYTHING.
