Narrative:

At the beginning of our shift [co-worker] and I took over the flap fail message on aircraft X. We started a zero rig procedure using the aircraft maintenance manual (amm). While we were raising the flaps and they were at about the zero position there was a sudden noise from both flaps. When I looked at all of the flaps I found damage to both inboard flaps.we found that in a caution note the amm mentions removal of a bracket; however this is not a step in the task; there is also no step to reinstall the removed bracket at the end of the task.this bracket removal should be a separate step in the task and not simply an added 'caution'. There should also be a step for reinstalling the removed bracket.
