Narrative:

Departed F69 to 7tx4 (hillcrest) via 52F (northwest regional). Arrived 52F approximately 12 mins after departure on heading of 268 degrees, then erroneously turned southeast (approximately 130 degrees) instead of southwest (heading 197 degrees). Route took me in to dfw's class B surface to 11000 ft airspace without prior approval. Altitude at time of violation was approximately 1500 ft MSL. Upon noticing I had become disoriented and still unaware that I was in class B airspace, I executed a 180 degree turn to depart the area and at that time, although not on a collision course, came close enough to an MD80 to set off the plane's TCASII warning system. Airspace violation was caused by misreading the dfw terminal chart, mistaken compass heading and the relative closeness of the small, private destination airport to dfw's surface class B airspace. Upon entering afw class D airspace, I was notified by the tower of my navigation mistake and cleared to land at 7tx4. Upon arrival, I voluntarily called the afw tower and they referred me to the dfw tower. Approximately 2 hours later, due to their line being busy, I contacted the tower and gave them my complete contact information. As of sep/xa/98, no one has contacted me. This incident resulted in no damage to property or persons and was unintentional. Corrective action to prevent future violations, is to pay closer attention to navigation charts.

Title: A PA28 PVT PLT ENTERS THE CLASS B AT DFW WHEN HE GETS DISORIENTED. PLT TURNED SE INSTEAD OF SW FOR HIS DEST ARPT OF 7TX4. DURING EVENT HE SUFFERED A POTENTIAL CONFLICT WITH AN ARR MD80 ON APCH TO DFW.

Narrative: DEPARTED F69 TO 7TX4 (HILLCREST) VIA 52F (NORTHWEST REGIONAL). ARRIVED 52F APPROX 12 MINS AFTER DEP ON HDG OF 268 DEGS, THEN ERRONEOUSLY TURNED SE (APPROX 130 DEGS) INSTEAD OF SW (HDG 197 DEGS). RTE TOOK ME IN TO DFW'S CLASS B SURFACE TO 11000 FT AIRSPACE WITHOUT PRIOR APPROVAL. ALT AT TIME OF VIOLATION WAS APPROX 1500 FT MSL. UPON NOTICING I HAD BECOME DISORIENTED AND STILL UNAWARE THAT I WAS IN CLASS B AIRSPACE, I EXECUTED A 180 DEG TURN TO DEPART THE AREA AND AT THAT TIME, ALTHOUGH NOT ON A COLLISION COURSE, CAME CLOSE ENOUGH TO AN MD80 TO SET OFF THE PLANE'S TCASII WARNING SYS. AIRSPACE VIOLATION WAS CAUSED BY MISREADING THE DFW TERMINAL CHART, MISTAKEN COMPASS HDG AND THE RELATIVE CLOSENESS OF THE SMALL, PVT DEST ARPT TO DFW'S SURFACE CLASS B AIRSPACE. UPON ENTERING AFW CLASS D AIRSPACE, I WAS NOTIFIED BY THE TWR OF MY NAV MISTAKE AND CLRED TO LAND AT 7TX4. UPON ARR, I VOLUNTARILY CALLED THE AFW TWR AND THEY REFERRED ME TO THE DFW TWR. APPROX 2 HRS LATER, DUE TO THEIR LINE BEING BUSY, I CONTACTED THE TWR AND GAVE THEM MY COMPLETE CONTACT INFO. AS OF SEP/XA/98, NO ONE HAS CONTACTED ME. THIS INCIDENT RESULTED IN NO DAMAGE TO PROPERTY OR PERSONS AND WAS UNINTENTIONAL. CORRECTIVE ACTION TO PREVENT FUTURE VIOLATIONS, IS TO PAY CLOSER ATTN TO NAV CHARTS.
