Hello again, Just wanted to post some pictures of my bird. When I bought the plane the logs had been long lost and the plane had sat outside for many years in the California desert. As an AP/IA, the only way I could re certify this plane is take it apart, inspect and re assemble. In the process we found some pretty serious corrosion in some hard to inspect spots. The tail cone had 3 stringers wit inner granular/ and exfoliation corrosion. We drilled out all the rivets in the tail cone, replaced the damaged material, treated surface corrosion, primed and painted the parts and re assembled, Next we looked at the stabilizers. on the vertical stabilizer we noticed the channel on the bottom of the main vertical spar where it was spot welded. The spot welds were actually pulling away from the spar because of corrosion between the 2 skins. We were then forced to disassemble the vertical where we found the skins had too much surface corrosion and one the ribs had a corrosion hole about the size of a quarter in it. We blasted, Treated primed and painted all the ribs, Fabricated a new channel for the spar and made new skins. Put it back together then moved to the horizontal. We noticed that it had several blind rivets in it. That means that a rivet failed (more than likely corrosion) We de-skinned it and sure enough found a couple corroded ribs, new skins and serviceable replacement ribs and that is back together. We then noticed that all 4 blocks that the wings bolt in to (the ones with the eccentric bushings) Were exfoliating and flaking apart. We removed them and found the rear carry through corroded through between the spar and the block, also on the top of the front carry through spar there is a spar cap,The spar cap had a large corrosion hole through it but it did not damaged the spar. We fabricated a new spar cap and are working on the rear spar. I'm sure there is still more discoveries to be made as we continue to work. I wanted to share this with you guys so you can be on the look out with your planes. I will attempt to upload pictures. The site keeps telling me the files are to large. My shop Ben's Motorworks is doing all the work in house. That being said of any of you need any 170 work or sheet metal work here on the west coast we are capable. We are located at KFUL in Southern California. Real close to Disneyland.
Have a great day. Were getting "the Storm of the century today" So I guess it time to close the door and shoot some rivets.
