We were parked in the overflow area for ZZZ. We were to taxi between a PC-12 on the right and a Caravan on the left; it was a rather tight fit; but it looked doable. We needed to pull forward to make a tight right turn to go in between the 2 aircraft. We had 1 ramp employee wing walking on the left side; between the Caravan and our aircraft. He was giving a thumbs up/all clear signal so I continued to move forward. By the time I was given the stop signal; I did not have enough time to come to a stop; resulting in contact between my left wing tip and the tail of the Caravan. I then came to a stop and shut down the engine. After shutting; I addressed the passengers and then exited the aircraft to inspect the damage. The left wingtip of our aircraft had a small scratch; but no other damage was visible. The tail of the Caravan has a sizable dent on the underside of the tail where it made contact with the wing. After talking to the ramp employee; he said that he attempted to give us a stop signal; but knew it was too late. He also said he attempted to stop the aircraft by grabbing it with his arm; resulting in a bruise on his left forearm. As for a more detailed step by step of the incident:After startup and the before taxi checklist; I flashed my taxi light to indicate we were ready to begin taxi. The single lineman was not directly in front of our aircraft; but standing just to the right; directly behind the tail of the Caravan. He didn't give the typical 'move forward' motion with his arms; just a thumbs up to indicate we were good to start moving. I released the brake and began moving forward a few feet; before turning to right towards the taxiway and the gap between the aircraft. The First Officer was focused on the right wing; announcing a 'clear right'. As my left wing approached the Caravan; the lineman gave thumbs up indicating we were clear of the other aircraft; so I announced 'clear left'. I looked forward and briefly looked to the right to assess the distance. As I looked back to the left; from my perspective it looked clear; but a little close; so I attempted to slow down and turn to the right. This is when I was given a stop signal; but as I began applying the brakes is when the wing made contact with tail of the Caravan. [I] suggest more wing walkers when taxiing out of the overflow area in ZZZ.
We were parked at ZZZ in the overflow ramp. There was another Pilatus to our right and a Caravan parked in front of us. Normal startup; a line guy came out to marshal us because the space between the Caravan and Pilatus to our right was tight. Pulling forward; the Captain started a slow right turn; watching his wing and the line guy; while I watched the right wing. As we pulled forward and slightly to the right; once clear of the Pilatus I called clear right. The Captain said the line guy gave him the thumbs up that he was clear and he called clear left. We needed to continue the turn around to the right to turn back for the assigned taxiway. As the Captain called clear left when he got the signal he briefly turned his head to check the front of the plane and when he looked back he hit the brakes but we were too close and struck the underside of the tail of the Caravan. Captain immediately stopped the aircraft and shutdown where we were. We checked on the passengers and got out to assess the damage. While talking to the lineman afterward he stated that by the time he had given us the signal to stop he knew it was too late. The lineman did state that he had attempted to grab the wing last minute and had what looked like a decent bruise forming on his arm. The left wing of the aircraft has a scrape on the wing tip; but doesn't seem dented or badly damaged. The Caravan did have a decent dent on the bottom of the tail.
PC-12 flight crew reported a ground collision with another aircraft while maneuvering in overflow parking.
