Narrative:

On aug/thu/05; I and technician Y went to ZZZ; continued the installation of #3 kruger flap (serial #XXX) on aircraft X that technician Z from previous shift didn't finish. As per the manual; we continued where technician Z left off. I continued to step 19. At step 20 I didn't get the clearance called out; so I brought it to the attention of inspector a and foreman B as to decide next course of action. At the end of the shift; I signed for completing steps 1J to 19 thinking that engineering would give the clearance. I turned the aircraft over to next shift. They couldn't get relief so they removed #3 kruger flap and installed another which was robbed from another aircraft; while leaving my signature for steps I completed on serial #XXX. Note: the reason the clearance didn't meet the amm is because engineering authority/authorized xxxxx was done on serial #XXX. The flap I helped install had stickers with engineering authority/authorized xxxxx stuck to the inside of the flap. The paperwork only shows the original flap removed and the robbed flap installed. I am writing this because paperwork shows me signing for the installation of the robbed flap; which I had no hand in. There is no mention of the removal of serial #XXX by the next shift mechanics.
