Narrative:

On VOR 17 approach into pwg approximately 3 mi south of act VOR on 185 degree radial; descended below MSA on approach prior to reaching missed approach. I was established on the approach; had full WX brief. I believe that I received a modified missed approach procedure during final phase of approach and; after readback of procedure; I thought I had passed the FAF. I then began a descent below the published altitude prior to reaching the FAF. In the future; I will not let ATC or other factors distract me during the approach procedure to ensure that this does not happen again.
