Narrative:

[I was] making a crosswind landing [with] wind [at] 18 gusting to 28 [KTS] and experienced windshear as I approached the runway; left wing down; right rudder. The airplane dropped. I added full power and executed a [touch and go] takeoff. I was not aware of any damage and continued to fly to another airport for practice ILS approaches. Upon landing back at home base and after shutting down the aircraft; I noticed that the blade tips were bent. While flying I experienced no vibration; nor any unusual flight characteristics. I was surprised to see that there was any damage at all. In the morning I reported the incident to my mechanic and he said he would repair the prop and send out the engine for inspection. According to part 830 [in the] far/aim; a prop strike is not considered a reportable incident. This morning; mr. X from the state airport corporation came to the airport and said he was here to investigate the accident. He demanded that I surrender my FAA license and medical (not just show it to him). I also wanted to call AOPA legal first. Inspector X was adamant; but I called anyway and did not hand over my documents until he promised he would return them immediately after making photo copies. The AOPA lawyer said to refer everything to him. Inspector X said he was going to call the state police and have me arrested. I am about to leave the airport and see if I get arrested.
