Narrative:

After a short flight, the owner was flying, we returned to the airport and landed. My friend who is an ATP, CFI, sitting in the right seat, said he was not current in the aircraft and would like to try a high speed taxi down the runway to get the feel of it. During the high speed taxi the aircraft began to porpoise. He had difficulty getting it under control and felt he might run out of runway so he elected to add full power and fly. I got in the left seat and made 2 takeoffs and lndgs, both normal and uneventful. After returning to the hangar we noticed that the propeller had damage on both tips. None of us had noticed or felt anything which would lead us to believe that the propeller had struck the ground. It was at this point I realized I was not current in the aircraft. It is wise to have a check out in an aircraft you have not flown for some time before attempting a flight. The excitement of the moment and complacency of flying every day contributed to my overlooking the fact I was not current. It would be a good idea to shut the engine down and inspect the aircraft after an unusual event and not assume all is fine. Supplemental information from acn 128252: gusty winds lifted plane off runway and we started to go up and down approximately 2-3 times. Told pilot to take off and I called tower to announce our intentions. We continued to fly and practice takeoffs and lndgs with the 3 people. Each had 2 or 3 touch-and-goes. Upon removal of cowlings on nov/mon/1989 it was discovered that the front wheel had been pushed up into the firewall and needed repair.
