So I was taking some time today to clean the bugs off my 140. As I was wiping down the prop, I noticed a crack in the paint that was in a straight line from the leading edge on the face going toward the trailing edge. It’s about 2” or 2.5” long. It had a spot that was bubbled in the middle of the crack from corrosion under the paint. I took my fingernail and scraped the paint off the corrosion area. It really looks like the prop is cracked. If you look at the picture and start at the bottom of the crack and follow it up to where the bare aluminum is. It looks like that line extends into the aluminum. It could be where moisture was trapped in the paint crack and corroded the aluminum. But to me it sure looks like the prop is cracked. I took the picture with my cell phone and enlarged it. So it looks big, but it’s really about 2.5” long. I’m grounded until Monday so the mechanic can put some dye penetrant on it and then I will know weather I have a prop for my wall. Hoping for the best, preparing for the worst!!!
