Narrative:

At john tune airport there is a helipad painted on the airport apron where helicopters frequently land for fuel and services. I was approaching the helipad from the north (winds were generally light out of the south) on a normal approach angle. The conditions were very dark with no illumination from the moon. I had made all of my radio calls stating my intentions with no response from the unicom. I was at an altitude of approximately 50 ft AGL when I realized that there was an airplane being pushed directly onto the helipad that I was landing to. As I adjusted my landing angle to land to a clear space on the airport apron; I noticed that there was a tug pushing this dark unilluminated airplane onto the helipad. The only lights the line personnel had on were the headlights on the tug. After I landed and shut down the helicopter I walked over and asked if they knew they were parking airplanes on a helipad. They complained that there was nowhere else to tie them down. I asked if they could have let someone know that the helipad was closed and they responded that they would NOTAM the helipad in the morning.
