Does this sound basic? Yes, it is…. BUT, there continue to be maintenance-induced aircraft accidents where the mechanic did not follow the order of the steps, did not finish a step, or did not complete all the steps of the task as instructed.
Instructions for continued airworthiness contain sequential steps for completing a task. It goes without saying (but we'll say it anyway!) that the sequence of steps developed by the manufacturer is very important! The job will be performed correctly and safely when each individual step is started and completed; one step at a time, in sequential order.
It is not a bingo game out there, it really is a matter of safety, and safety cannot be compromised.
