I think you are been very anul with your reply Miles, There is a vast difference between G.A and Commercial aircraft you come accross as a pen pusher not an engineer with that reply. BY the sound of it AVGASANDY appears to sign off everything with an I.A.W and there is a section in his work pack asking have all panels been refitted.
If i was stood at the side of a 747 and asked if the opposite sides engine cowls were on or off i would have to walk round and take a look so yes a separate entry in the work pack is a good thing to have, However if asked the same of a PA28 i could answer that no matter what side of the aircraft i was on. So (have the all panels been refiitted section should be fine).
