Narrative:
I was needing to change a bulb seal inside the #2 krueger flap. Hydraulics were tagged out pressure bled off. While trying to get the job done quickly I forgot to install the krueger flap locks. The FAA guy walked up and pointed the problem out. All work was stopped immediately and locks were installed and job was completed. To prevent this from happening again all locks must be installed prior to maintenance.
