B747-400 to frieghter differances
 

Has anybody got or can point me in the right direction for these diff notes.
Many thanks

I'm not sure you actually find much in the way of "notes" for differences between B747-400 passenger and freighters? Having worked on all types of B747 except the -8 [so 100/200/300/400/SP] in both passenger and combi and pure freighter type, I cannot remember any specific notes for freighter differences, only notes, were for type differences. Some companies might have issued them but I don't remember seeing any such notes.

Main differences would be strengthened main deck floor [which was only strengthened in the convertible part of a combi] Special inspections around SCD area [side-cargo door] and nose opening door area. Extra fire suppression systems on main deck. Powered cargo handling system main deck [but this was just a copy of the lower deck system with just more control panels throughout the main deck] Also the combi versions had a removable system on the main deck, as were the fittings for passenger seating and overhead bins in the zones that were convertible between passenger and freight.

Pure freighters [that were built as such from Boeing] also had the smaller upper deck as the larger upper deck was not required.
