Narrative:
On jun/xa/01 I changed the l-hand inboard flap transmitter. I performed the required maintenance manual checks, except I did not do the asymmetry check. During a functional check of the same inboard flap transmitter on aircraft, I realized I had forgot to do this portion of the test on aircraft.
