Narrative:

I was inbound into del rio international (drt) level at 2300 ft under the outer ring of the laughlin class C airspace and flew through the class east extended airspace which was active. A citation jet was on approach and flew underneath my aircraft. After landing at drt; I was to contact and did have a conversation with the controller/supervisor on duty at the time. He stated that I was in laughlin airspace which had a 1.2 mi extension off the center ring of laughlin and that he designated as class D airspace. He also stated that it was a 200 ft separation between our 2 aircraft. The controller took my name and aircraft tail number. I was flying into drt using my garmin 430 which does not show the class east airspace on the moving map but after landing did view it on the sectional that I had in the aircraft. I believe I was authority/authorized to be in that airspace but if I would have been paying more attention to the sectional than the garmin 430; I would not have been in that airspace intentionally.
