Narrative:

On this date, I had a generator failure. It was dark and I was on battery power. 20 mi out, I began squawking 7600 in an attempt to let sat know I had problems. I turned off all items not needed. I flew the helicopter approach to sat. I held just north of sat waiting for light gun signals to land. I held for about 10 mins. Still no light signals were observed. Having 3 passenger and it being nighttime, I didn't want to fly to an uncontrolled airport north of sat and try to land with no power or landing lights as well as position lights. I had no radio power to turn on runway lights or taxiway lights. As the captain of this flight, I chose to fly to an airport that I knew well enough to land safely. I waited north (1 mi) until no aircraft was observed in the traffic pattern or on final. Also, no aircraft movement on the ground as well, was observed. Still with no light gun signal coming from the tower, I decided to go ahead and land. I remained clear of all runways and txwys and landed at sat. After landing, I called the sat tower and spoke with the controller in charge. The controller didn't even know I had landed at sat, and that there was no problem. The main reason that I am writing this letter is I landed and flew in controled airspace without a clearance. Due to my emergency, I felt I had no other choices that were safe for myself as well as my passenger. If you have any questions, please feel free to contact me at any time. Thank you for your time.
