"If this was a 747 then fair do but its quite obvious on a puddle jumper if the cowl is missing."
Great, now we have engineers thinking that it is ok to have double standards because it's a little aircraft!
145 is clear on carrying out work, and you are suppose to sign for everything you do, and either carry out a written handover of the work or process out the work so it is clear what the status of work is... and it isn't a weight or type issue, it's to every aircraft.
If you extend the "small" aircraft argument where does that leave us with the helicopter community?
I appreciate that 145 and Part M may be onerous for small operations but thats just tuff and the cost of operating in the modern aviation world is expensive!
