I'm an engineer and while I do believe that the PF should carry out his preflight walkaround in accordance with Flight Crew Operating Manuals, I feel its totally unfair that the Capt/FO who did the check in this particular case is should be lambasted in any way.. A task that has been stated in other forums by engineers in the know of this companies proceeduresand that would be stated on a task card as requiring signing as a duplicate inspection was signed and not done.
Just culture applies so the reasons why it wasn't done must be investigated..
The wording AMS's comes into play.. I have heard that before at another company.. Approved Mechanics? AKA Car Mechanics who have been crash coursed A Modules and given approvals after a couple of years? Am I on the ball?
