Pilot narrative
Verbatim, de-identified by NASA. Placeholders: ZZZ,
X, Y.
I was doing a 100-hour inspection and found that the uplock roller was not moving freely on lefthand landing gear and per 100-hour inspection, it had to move freely. I made a write-up about it not moving freely and decided to change the uplock brackets and roller pin in accordance with the CMM (Component Maintenance Manual). I had thought that I had correctly installed the uplock brackets but I mistakenly installed them upside down. Uplock brackets were mistakenly installed upside down. Do a gear swing of the aircraft to make sure that the job was done correctly.
