Narrative:

On may/xx/90, I flew a helicopter into an air traffic area located at ZZZ, west/O permission or radio contact. While conducting an EMS mission from abc, to xyz, I was directed to transport a motor vehicle accident from hospital a in xyz to abc. Upon departure from xyz, I was directed to take the patient to hospital B in zzb. During the early stages of the flight to zzb, the doctor and flight nurse questioned me to how long the flight would take and indicated a trauma team was waiting to take the patient to the operating room immediately. I knew the flight was only going to take 12 to 15 mins. I started calling zzb tower at about 10 mi out. I called at least 3 times, however I was trying to contact them on 122.8 instead of CTAF 125.7. I knew the airfield had a parttime operating tower. Once I realized I was receiving no contact, I turned from a heading of 220 degrees to a heading of 240 degrees in an attempt to go around the air traffic area. After about 3 mins, I turned back to a heading of 220 degrees. This was a mistake. The air traffic area area included the hospital so there was no way I could fly around it. As I xed a treeline on a heading of 220 degrees, I realized I was crossing the airfield. I noticed an aircraft below me departing on runway 130, making his ground run, I realized I was in the middle of the air traffic area. Upon my arrival to hospital B, I received a message to call the tower chief. I explained the circumstances and he said no action would be taken. He reminded me that I have to have permission to fly into an air traffic area. I apologized and accepted responsibility. I believe this occurred because I failed to review the vr sectional, mistaking zzb tower for unicom station. It was poor judgement on my part. I was involved in patient care when I should have been totally involved in flying.

Title: GA SMA HELICOPTER UNAUTH PENETRATION OF ZZZ ATA ON EMS FLT.

Narrative: ON MAY/XX/90, I FLEW A HELI INTO AN ATA LOCATED AT ZZZ, W/O PERMISSION OR RADIO CONTACT. WHILE CONDUCTING AN EMS MISSION FROM ABC, TO XYZ, I WAS DIRECTED TO TRANSPORT A MOTOR VEHICLE ACCIDENT FROM HOSPITAL A IN XYZ TO ABC. UPON DEP FROM XYZ, I WAS DIRECTED TO TAKE THE PATIENT TO HOSPITAL B IN ZZB. DURING THE EARLY STAGES OF THE FLT TO ZZB, THE DOCTOR AND FLT NURSE QUESTIONED ME TO HOW LONG THE FLT WOULD TAKE AND INDICATED A TRAUMA TEAM WAS WAITING TO TAKE THE PATIENT TO THE OPERATING ROOM IMMEDIATELY. I KNEW THE FLT WAS ONLY GOING TO TAKE 12 TO 15 MINS. I STARTED CALLING ZZB TWR AT ABOUT 10 MI OUT. I CALLED AT LEAST 3 TIMES, HOWEVER I WAS TRYING TO CONTACT THEM ON 122.8 INSTEAD OF CTAF 125.7. I KNEW THE AIRFIELD HAD A PARTTIME OPERATING TWR. ONCE I REALIZED I WAS RECEIVING NO CONTACT, I TURNED FROM A HDG OF 220 DEGS TO A HDG OF 240 DEGS IN AN ATTEMPT TO GO AROUND THE ATA. AFTER ABOUT 3 MINS, I TURNED BACK TO A HDG OF 220 DEGS. THIS WAS A MISTAKE. THE ATA AREA INCLUDED THE HOSPITAL SO THERE WAS NO WAY I COULD FLY AROUND IT. AS I XED A TREELINE ON A HDG OF 220 DEGS, I REALIZED I WAS XING THE AIRFIELD. I NOTICED AN ACFT BELOW ME DEPARTING ON RWY 130, MAKING HIS GND RUN, I REALIZED I WAS IN THE MIDDLE OF THE ATA. UPON MY ARR TO HOSPITAL B, I RECEIVED A MESSAGE TO CALL THE TWR CHIEF. I EXPLAINED THE CIRCUMSTANCES AND HE SAID NO ACTION WOULD BE TAKEN. HE REMINDED ME THAT I HAVE TO HAVE PERMISSION TO FLY INTO AN ATA. I APOLOGIZED AND ACCEPTED RESPONSIBILITY. I BELIEVE THIS OCCURRED BECAUSE I FAILED TO REVIEW THE VR SECTIONAL, MISTAKING ZZB TWR FOR UNICOM STATION. IT WAS POOR JUDGEMENT ON MY PART. I WAS INVOLVED IN PATIENT CARE WHEN I SHOULD HAVE BEEN TOTALLY INVOLVED IN FLYING.
