We ran across an article the other day noting that Lockheed Martin’s F22 jets are having corrosion problems with their aluminum skin panels due to poor drainage. They estimate it will cost $228 million to repair the damages. The jets were placed into service in 2005 by the U.S. Airforce. I had to wonder if repair, or altogether replacing the material choice was the best solution. I guess they asked themselves the same question – as Defense Secretary Robert Gates limited production of the F-22 to only the 187 planes already on the ground.

This is one of the known common problems with Aluminum in addition to cracking. Want to know more? Here’s the story on Bloomberg News.
