SINGLE ENG ACFT PLT ENTERS WRI AIRSPACE WITHOUT CLRNC.

Narrative

I DEPARTED OLD BRIDGE ARPT; NJ (3N6); ON A FLT FOR GRAND STRAND; SC (CRE). THE FLT PATH WAS TO BE 3N6 TO RBV TO SBY TO CRE. AFTER TKOF; I PROCEEDED TO RBV VOR. MY SON; A STUDENT PLT; WAS IN THE R SEAT AND AT THE CTLS. HE WAS INSTRUCTED BY ME TO MAINTAIN A HDG AND CLBOUT AT A SLOW RATE. VISIBILITY WAS HAZY; WITH SUN DIRECTLY IN FRONT OF US. AFTER TKOF I CALLED MCGUIRE AFB ON 120.2 WITH NO RESPONSE. I TRIED CALLING THEM A FEW TIMES AND THEN DECIDED TO CHK TO SEE IF I HAD THE CORRECT FREQ. THEIR FREQ TURNED OUT TO BE 120.25 AND I ADJUSTED THE RADIO APPROPRIATELY. NOW I WAS ABLE TO HEAR THE CTLR ON THE FREQ. I CALLED 2 OR 3 TIMES ON FIRST RADIO WITH NO RESPONSE. I THEN SWITCHED TO MY SECOND RADIO AND CALLED 2 MORE TIMES. NO RESPONSE. I WAS PUZZLED BY THE LACK OF RESPONSE AND PROCEEDED TO LOOK FOR THE CAUSE. AFTER A SHORT SEARCH OF THE POSSIBLE CAUSES; I DETERMINED THAT I WAS WEARING THE WRONG HEADSET. I THEN SWITCHED HEADSETS AND CALLED 1 OR 2 MORE TIMES AND FINALLY RECEIVED A RESPONSE. I IDENTED SELF AS BEING AT 1700 FT AND ADJACENT THEIR ARPT. THE CTLR THEN ASKED IF THAT WAS ME 2 MI FROM ARPT. I SAID AFFIRMATIVE. I WAS THEN ADVISED THAT I VIOLATED MCGUIRE'S AIRSPACE; TO LEAVE AIRSPACE AND CLB TO 2500 FT. I TURNED N AND CLBED AS QUICKLY AS POSSIBLE TO 2500 FT. IT APPEARS THAT I VIOLATED THE CLASS D AIRSPACE. AIRSPACE INCURSION WAS DUE TO ATTN BEING GIVEN TO THE RADIO PROB AND NOT ACFT LOCATION. VISIBILITY WAS A SECONDARY FACTOR. THIRD WAS HAVING THE PLANE FLOWN BY SOMEONE WHO WAS NOT FAMILIAR WITH THE CLASS D AIRSPACE. FOURTH; RELYING ON MY GPS WHICH DOES NOT WARN OF CLASS D AIRSPACE BUT DOES WARN OF CLASS B AND CLASS C.
