Last weekend I had an opportunity to assist three guys who were changing a C-Duct (a thrust reverser half) on one of our planes.This plane had been down for two days now costing the company big money. TR halves are very expensive (about half a million bucks I’ve been told) so we were spending some money that day. These guys had the old TR half off by the time I got out there. I was just going to snap a few pics and be on my way but since I had never changed one before I wanted to check out what they were doing.

It turns out that I was able to help out a little with the installation of the new TR half. It was really windy that day so it was good that I hung around. When Brooklyn picked up the TR half the with the fork lift the wind caught it immediately and it took two of us to steady the thing while it was positioned.
The different slings and hoists that are engineered to accomplish jobs like this always amaze me. The set up they sent for this was a chain hung from the forks on the fork lift going to a block and then to a pole that connects into a big C shaped frame that connects onto the C Duct.

Those guys got the old C Duct off and the new one on in about two hours! That’s a pretty good time. I learned a little along the way and except for the wind it was a very smooth job.
