Two friends flying a piper arrow suffered a prop strike and some skin damage when the landing gear failed to extend normally while still providing three gear safe lights. A go-around was conducted after the first impact with no obvious performance decrement although an after flight inspection revealed the tips of all three propeller blades were bent backwards 90 degrees and some minor flap damage resulted.

Narrative:
My friend and I [his instructor] were flying another friend's piper arrow practicing commercial maneuvers. The whole flight up till landing was fine. When we came back in for landing I had told him my part was over; he was PIC and in charge of the rest of the flight. So he came in for landing like normal. He put one notch of flaps in to slow us then I saw him extend the gear lever and I peeked over and verified three green for the gear. He continued the approach and put the rest of the flaps in. As he pulled into the flare about to touch down we heard a scraping noise and he immediately pushed the throttle full power and pitched up for a go around. After departure he ran the emergency checklist and determined that a circuit breaker for the hydraulic pumped had popped and as soon as he pushed it in the three green came on again. Subsequently after the gear came up fully the three green went out; and when he put the gear lever back down they all lit up again. The entire approach I kept my eye on the circuit breaker to make sure it didn't happen again. He landed safely and normal. After parking we inspected the piper arrow and concluded minimal prop damage and a little damage to the sheet metal on the left flap. This had happened on a previous flight in the same arrow but it was on takeoff and the gear stopped mid cycle. He pushed in the circuit breaker and it came up. We did inform the owner/operator and he assured us it was fixed and not an issue. In conclusion; we were baffled as to why or what even happened to cause this malfunction. We're not sure if the gear was fully extended or not. We both verified three green at least once. One thing is for sure; the circuit breaker for the hydraulic pump did pop and he isn't exactly looking at that for every last ding.
