June 2014 update on the restoration of the Burnelli CBY-3 "Loadmaster" from restoration Crew Chief, Harry Newman.
Interior cleaning of the fuselage continues. The plywood floor decking had deteriorated and some panels were missing. All of the cargo and cockpit flooring has been removed and replacement floor panel fabrication has begun. This necessitated the removal of the engine oil replenishment system which was installed in a rear storage area and piped to the engines. The oil tanks, mounts and hardware have been cleaned and stored for future installation.
The fuselage contains a number of interior hatches that were constructed of wooden framework sandwiched between sheet metal. In all cases the wood has deteriorated which requires the hatches to be completely disassembled in order to replace the wooden interior. This involves the removal of hundreds of rivets and tiny screws in each hatch as well as detailed carpentry work.
The retractable cargo doors, mounted on both sides of the fuselage, have also been removed for restoration and to facilitate access to the wing mounting hardware in preparation for wing removal.
Due to rust and corrosion the removal of the wings proved much more difficult than anticipated. Two of the eight one inch diameter mounting pins had to be drilled out, a long and laborious process. At last the wings were freed of their mounts and carefully lowered. They will require extensive refurbishment and sheet metal replacement due to preexisting damage and corrosion. The next step will be to mount the wings in stands to facilitate the work and to move them into our restoration facility.
