Swissair Flight 111 - Examination and Investigation

Examination and Investigation

An estimated 2 million pieces of debris were recovered and brought ashore for inspection at a secure handling facility in a marine industrial park at Sheet Harbour, where small material was hand inspected by teams of RCMP officers looking for human remains, personal effects and valuables from the aircraft's cargo hold. The material was then transported to CFB Shearwater where it was assembled and inspected by over 350 investigators from multiple organizations such as TSB, NTSB, FAA, AAIB, Boeing, Pratt & Whitney, and Swissair.

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 then 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.
