Narrative:

I left M66 at XA00 for a flight that would take me first to lvn to pick up a friend and then on to mos. Since the first leg would be largely under msp class B airspace, I had meticulously planned out that part of the trip (headings, altitude, landmarks, etc). The flight to lvn went without incident. The next leg to mos would be VFR in class east airspace with a landing at mos class G. Since almost all of my flying is out of uncontrolled airports, I have a habit of climbing directly to cruise altitude when VFR, and since lvn is near the outer ring of msp class B, my mind simply assumed I would be clear of class B before I climbed through 4000 ft MSL. My better judgement never questioned it. I now realize it is possible I could have unintentionally climbed through 4000 ft while still 2-3 mi inside msp class B airspace. I pride myself in being safe and professional in my flying and never realized how one simple lapse in judgement could cause a possible airspace violation or worse. While I will be much more careful in the future, perhaps a sign at the end of the taxiway warning pilots they are underlying class B airspace would prevent this type of incident.

Original NASA ASRS Text

Title: BE76 PLT BLUNDERED INTO MSP CLASS B AIRSPACE WITHOUT CLRNC.

Narrative: I LEFT M66 AT XA00 FOR A FLT THAT WOULD TAKE ME FIRST TO LVN TO PICK UP A FRIEND AND THEN ON TO MOS. SINCE THE FIRST LEG WOULD BE LARGELY UNDER MSP CLASS B AIRSPACE, I HAD METICULOUSLY PLANNED OUT THAT PART OF THE TRIP (HDGS, ALT, LANDMARKS, ETC). THE FLT TO LVN WENT WITHOUT INCIDENT. THE NEXT LEG TO MOS WOULD BE VFR IN CLASS E AIRSPACE WITH A LNDG AT MOS CLASS G. SINCE ALMOST ALL OF MY FLYING IS OUT OF UNCTLED ARPTS, I HAVE A HABIT OF CLBING DIRECTLY TO CRUISE ALT WHEN VFR, AND SINCE LVN IS NEAR THE OUTER RING OF MSP CLASS B, MY MIND SIMPLY ASSUMED I WOULD BE CLR OF CLASS B BEFORE I CLBED THROUGH 4000 FT MSL. MY BETTER JUDGEMENT NEVER QUESTIONED IT. I NOW REALIZE IT IS POSSIBLE I COULD HAVE UNINTENTIONALLY CLBED THROUGH 4000 FT WHILE STILL 2-3 MI INSIDE MSP CLASS B AIRSPACE. I PRIDE MYSELF IN BEING SAFE AND PROFESSIONAL IN MY FLYING AND NEVER REALIZED HOW ONE SIMPLE LAPSE IN JUDGEMENT COULD CAUSE A POSSIBLE AIRSPACE VIOLATION OR WORSE. WHILE I WILL BE MUCH MORE CAREFUL IN THE FUTURE, PERHAPS A SIGN AT THE END OF THE TXWY WARNING PLTS THEY ARE UNDERLYING CLASS B AIRSPACE WOULD PREVENT THIS TYPE OF INCIDENT.
