Many thanks to everyone involved in the lift of Corsair FG-1D BuNo. 92460!
I didn't have a lot of time to take photos, but here's a link to a few of mine!

To sum up today's events; we arrived about 2:30 to start prepping for the lift. Winds were forecast 12 knots 90 degrees to the aircraft. A little worried since several tons swinging in the breeze could prove a little dangerous. I decided to wait the arrival of the crane from Quick Pick Crane Services. He told me that it should be no problem as long as we have tag lines on the tail and wing tie downs.
We were a GO!
Once the aircraft was rigged, we attacked the bolts. Now we've been spraying loosening agent on them regularly since last November and then trying a wrench every couple of weeks. We only managed to get one nut off. Today we were forced to cut three of the nuts off using a torch. Care was taken to not damage the bolt threads as they would be needed in the future to bolt the aircraft back on the pylon.
With tension on the Corsair we had to rock the airframe fore and aft and wing to wing using the tag lines to free the flat steel plate from the pylon. It loosened up and she "flew" off her perch at about 6:15 PM EST and over to the waiting truck chassie. Now using several experts, the empty weight with no landing gear and such was estimated at about 6,000 lbs. Well the crane operator said the lifted weight was 9,000 lbs!
A little off don't you think! No problem since the crane had a 20 ton capacity.
A truck chassie was located by Tim Brady of Three Wing Aviation Services, which by the way, had several employees involved in the lift.
Tim and his friend modified the frame by welding a steel plate on it with four holes that matched the pylon's bolt pattern. When the Corsair was lowered onto the frame we discovered that the outer dual wheels were rubbing the lowest part of the wing. We lifted the nose slightly and placed a 6X6 under the pylon mount. this raised the nose enough to clear the outboard tires by about one inch. Although the aircraft isn't sitting flat on the steel plate, it is bolted tight to it.
Once the aircraft was tightened down, the crane repositioned to between two hangars and the Corsair was towed over to the crane. There is no gate that the aircraft would fit through and it would take some time to work on folding the wings, so it was decided to do a second lift over some trees and one corner of the hangar and down onto an airport driveway.
Now the area where we were placing the Corsair was about 45-50 feet wide. The aircraft would fit, but it was tight. We had to lift it and swing it around with one long tag line on the tail to keep it under control. The chassie was towed around to another gate and then repositioned under the Corsair. Once lowered and bolted to the frame at about 7:15 PM EST, we packed up and were done for the day.
The next step is to have an outside person evaluate the airframe so that a plan of action can be drawn up and refurbishment plotted out.
It was a long road, but quite a relief to see it secure and on the airport!
Many thanks to everyone involved. It was a real team effort and everyone worked well together to solve the little hurdles we had to jump over.
The knots are now out of my stomach and I'm breathing a lot easier now!!!!
Blue skies,

PS: Thanks for posting those photos Jorge! I wish I could've taken a lot more.
BTW, I'm the one with the yellow hat on the middle of the group photo!
