Duplicate Inspection
DFC as you no doubt know after maintainance of a critical aircraft system (usualy a flying or engine control system) this has to have to have two independant inspections.
Under the CAA system this has to be two licenced engineers or some one with a CAA approval (very unusual)
The EASA system requires the second inspection but the person doing the second inspection can be nominated by the maintenance company, they dont have to be a licenced engineer or CAA approved.
I see this as a loop hole that the bottom end of the market will use to get the tea boy to do safety critical inspections.
