EMS HELI CREW ENTERS HOT MOA AT NIGHT AS A RESULT OF ACCIDENTAL NAV ERROR.

Narrative

DUE TO A SHORTAGE OF PLTS; I WAS FILLING IN AT CITY Z SINCE MAR/XA/99. I RECEIVED AN AREA ORIENTATION; WHICH DID NOT INCLUDE THE CITY A AIRSPACE OR SURROUNDING AIRSPACE. ON MAR/MON/99 I RESPONDED TO CITY B TO PICK UP A SERIOUSLY INJURED WOMAN AND TAKE HER TO THE TRAUMA HOSPITAL IN CITY A. I WAS FLYING VFR ON A COMPANY FLT PLAN AND FLT FOLLOWING. I WAS AWARE OF THE MDA AFTER DEPARTING CITY B AND HAD THOUGHT I WOULD MISS THE MOA BY FLYING TO THE S OF IT TOWARDS CITY A ARPT. MY PLAN WAS TO THEN CONTACT APCH AND GET VECTORS TO ARPT X WHERE WE WOULD MEET WITH AN AMBULANCE TO TRANSPORT THE PATIENT TO THE HOSPITAL. IT'S NOW EVIDENT THAT I WAS OFF ON MY NAV. I CONTACTED APCH AND WAS INFORMED THAT I WAS IN THE MOA AND IT WAS HOT. THE NEXT DAY I CONTACTED A SAFETY OFFICER WHO WAS INVESTIGATING THE INCIDENT AND EXPLAINED MY SIDE OF THE STORY. IN CONCLUSION; I HAVE BRIEFED OUR PLTS ABOUT THE EVENT WITH RECOMMENDATIONS SO THIS WILL NOT HAPPEN AGAIN. 1) BETTER (NEW PLT) ORIENTATION AND BRIEFING. 2) PAY CLOSER ATTN TO NOTAMS. WHAT CAUSED THE PROB? NEW PLT TO THE AREA UNFAMILIAR WITH THE AIRSPACE.
