Narrative:
I removed and replaced number 20 and number 6 fan blades on left engine of aircraft; and I believe I may have put the wrong blade back into the number 6 position. I had both new and old blades in my box and might have mixed them up.I was speaking to another mechanic and possibly mixed up the blades. [I need] to double check and even triple check serial numbers off parts being installed.
