In response to a previous column in which I expounded on the problem of exhaust valve recession with unleaded fuels, I received a note from Ron Newberg, which reminded me of work done by the oil companies back in the early 1970s. I actually ran some of these tests, in which we demonstrated that Tri-Cresyl Phosphorous (TCP) added to an unleaded fuel reduces the amount of exhaust valve recession. It worked well. Since TCP is approved for almost all aircraft piston engines, it is an immediate approved solution for the exhaust valve recession problem. But, alas, nothing is that simple. TCP will work, but it has some health concerns.

What reportedly happened: The student pilot was practicing touch-and-go landings. During the first approach she felt that her approach was too high, so she pitched down slightly, leveled off, and landed on the main landing gear. After landing, the plane porpoised twice and then landed flat and hard.
It’s no exaggeration — Atlanta traffic is bad. Even though we live 60 miles north of the city, my family lives three hours south. There’s no way around it. If I want to visit them, I must travel through a sprawling congested mess. The interstate straight through the city is often snarled and the loop around it is just as bad.
So when I learned to fly years ago, it was a relief to my Old Man that I finally had a safer mode of transportation to use when I wanted to see my family. He didn’t worry as much when I flew down in my C-172C than when I traveled by car. [Read more...]
