NO REAL ANOMALY OCCURRED. REPORTED TCA PENETRATION.

Narrative

I WAS TOLD AFTER I LANDED AT WILMINGTON; DE; THAT PHILADELPHIA SAID I WENT INTO THEIR SPACE. I DID NOT BELIEVE I DID. I HAD GONE ON THE LEFT (WEST) SIDE OF THE PHILADELPHIA TCA AND THOUGHT I WAS CLEAR BUT PHILADELPHIA TOLD WILMINGTON THAT I WASN'T. TO PREVENT THIS FROM HAPPENING I WILL GO DIRECT TO POTTSTOWN VOR AND SOUTH TO WILMINGTON. THE MAIN REASON I DIDN'T CALL PHILADELPHIA WAS YOU CAN NEVER GET THROUGH. IF YOU APCH IT FROM THE NORTH THEY WILL TELL YOU TO STAY CLEAR AND THEN YOU HAVE TO KEEP CALLING UNTIL THEY ANSWER. I HAVE EXPENDED 20 MINUTES AND LONGER CIRCLING ON THE NORTH SIDE. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING: CALLBACK INDICATES PLT FLIES THIS ROUTE REGULARLY AND MAINTAINS 2500' TO AVOID TCA. USED TO CONTACT WILLOW GROVE (NAVY) FOR TRANSITION AND THEN BE HANDED OFF TO PHL APCH. WOULD HAVE TO CIRCLE OVER THE TURNPIKE MANY TIMES BEFORE ANY RESPONSE FROM PHL. IT IS VIRTUALLY IMPOSSIBLE FOR GENERAL AVIATION PLTS TO GET RESPONSE FROM APCH. MOST LCL PLTS FLY WEST OUTSIDE OR UNDER TCA. REPORTER FEELS CTLR ATTITUDE IS THAT GENERAL AVIATION DOES NOT BELONG IN THE TCA AND THEY VECTOR THEM LONG DISTANCES AROUND WHEN PLTS TRY TO TRANSITION. REPORTER WAS ASKED TO REMAIN ON GND FREQ AFTER LNDG AS APCH WAS GOING TO CALL BACK. APCH NEVER CALLED.
