CLASS D AIRSPACE INCURSION BY A PVT PLT IN A PA28 ON AN AFTERNOON AT BED; MA.

Narrative

ONE AFTERNOON I FLEW A PA28 AT HANSCOM FIELD; BEDFORD; MA (BED) FOR THE PURPOSE OF PRACTICING TOUCH AND GOES AT THE ARPT. BY THE TIME I TAXIED INTO THE #1 POS FOR TKOF; THE PATTERN HAD GOTTEN EXTREMELY BUSY AND THE TWR SAID THAT THEY WERE UNABLE TO ACCEPT TFC FOR TOUCH AND GOES. I DECIDED TO TAKE OFF TO THE W (THE ACTIVE RWY WAS RWY 29) OUT OF THE ARPT'S CTL; CIRCLE TO THE N; AND RE-ENTER FOR A LNDG. APPROX 9 MI TO THE N AT A LCL RPTING POINT; I LISTENED TO THE CURRENT ATIS; SWITCHED TO THE BED TWR FREQ AND CALLED THE TWR ANNOUNCING MY INTENTIONS FOR A LNDG WITH THE ATIS INFO. THE FREQ WAS STILL EXTREMELY BUSY WITH NUMEROUS CONVERSATIONS STEPPING OVER EACH OTHER. I HAD TO CALL A NUMBER OF TIMES BEFORE I HEARD WHAT I THOUGHT WAS THE TWR ACKNOWLEDGING MY CALL. HE ALSO ANNOUNCED THAT DUE TO THE TFC; HE COULD NOT ACKNOWLEDGE ALL CALLS TO THE TWR AND THAT PEOPLE SHOULD RPT IN AS THEY ENTERED THE PATTERN. I CONTINUED ON TO THE ARPT AND DSNDED TO PATTERN ALT. I ALSO RPTED MY POS AT APPROX 3.5 MI OUT (GPS); BUT DUE TO THE RADIO TFC; DID NOT EXPECT A REPLY. I ANNOUNCED MY POS AGAIN AS I ENTERED THE PATTERN AT MID-FIELD DOWNWIND FOR THE RWY. AT THIS TIME THE TWR ADVISED ME THAT HE HAD NOT ACKNOWLEDGED MY CALL AND THAT I HAD ENTERED THE AIRSPACE WITHOUT PERMISSION AND SHOULD RETURN TO THE N RPTING POINT AND CALL IN AGAIN. I RETURNED TO THE N RPTING POINT; GOT THE NEW ATIS; CALLED THE TWR; AND WAS CLRED TO ENTER THE PATTERN AND LAND. THE PATTERN WAS STILL EXTREMELY BUSY AND; DUE TO THE TFC AND SETTING SUN (CAUSING VISIBILITY PROBS DUE TO THE RWY 29 LOCATION); TFC WOULD OCCASIONALLY GET CONFUSING AND SEQUENCING WAS CHALLENGING. OCCASIONALLY ACFT AND TWR WOULD LOOSE THE SEQUENCING AND TEMPERS WOULD GET FRAYED. I LANDED WITHOUT ANY FURTHER INCIDENT.
