As each piece of wreckage was brought in, it was carefully cleaned with fresh water, sorted, and weighed. The item was then placed in a specific area of a hangar at CFB Shearwater, based on a grid system representing the various sections of the plane. All items not considered significant to the crash were stored with similar items in large boxes. When a box was full, it was weighed and moved to a custom-built temporary structure (J-Hangar) on a discontinued runway for long-term storage. If deemed significant to the investigation, the item was documented, photographed, and kept in the active examination hangar. Particular attention was paid to any item showing heat damage, burns, or other unusual marks. The front of the aircraft, from the front of the cockpit to near the front of the first-class passenger cabin, was reconstructed. Information gained by this allowed investigators to determine the severity and limits of the fire damage, its possible origins, and progression.
