Oct 21, 1998 Deep-sea heavy-lift operation to retrieve the remaining material from Swissair Flight 111 is continuing
Oct 21, 1998 27% of SR-111 by weight has been recovered (including some very significant pieces)
Oct 22, 1998 Estimated that 48% of the aircraft by weight has now been recovered
Oct 23, 1998 A number of pieces of wiring were examined today, some of which exhibited heat damage
Oct 24, 1998 The "SEA SORCERESS" heavy-lift  ship hands over to the scallop dragger "ANNE S. PIERCE"
Oct 26, 1998 Sorting and identification of wires is continuing; the task is quite difficult especially for those wires on which there are no identification marks
Oct 27, 1998

More work is being done on examining the IFE system

Oct 28, 1998

Work is continuing on the IFE system. About 64 % of the aircraft by weight has been recovered

Oct 29, 1998 The wiring and structure, located in the ceiling in the vicinity of the cockpit, shows signs of heat damage. SR 747 and MD-11 IFE Systems are to be immediately disconnected.
Nov 02, 1998 200,000lbs of wreckage recovered and ROV operation begins
Nov 04, 1998 Fact Sheet on Nose Section Reconstruction Jig for Swissair Flight 111, MD-11
Nov 08, 1998 The team working on the examination of wire and wire bundles has been busy attempting to determine where the wires were located on the aircraft and to which systems they were connected. This aircraft has over 165 miles of wiring
Nov 11, 1998 Examination of wires and wire bundles is continuing as is the attempt to determine their location within the aircraft. Work is also under way to determine the heat damage pattern within the aircraft
Nov 17, 1998

Approximately 80 per cent of the aircraft, by weight, has been recovered. The recovery operation will continue until the laser line scan operation begins

Nov 20, 1998 Laser-line-scan and side-scan sonar of the aircraft debris field are being carried out to establish the outer limits of the field and to locate additional debris. #2 engine not producing power on impact.
Dec 21, 1998 Material is still being recovered from the seabed with the scallop dragger "ANNE S. PIERCE." Reconstruction of the forward section of the fuselage is continuing
Jan 24, 1999 Detailed Summary in bullet form of work underway and planned
Jan 28, 1999 Preliminary examination indicates that the Air-Driven Generator (ADG) was not deployed. The ADG can be deployed to provide electrical power if the other electrical generator buses are lost. VideoGrab Operations continue.
Mar 05, 1999 88 per cent of the aircraft structure, by weight, has been recovered. With a flap setting of approximately 15 degrees, it would normally be expected that the slats would have been deployed. Investigators are attempting to determine why the slats were not deployed.
Mar 09, 1999 TSB Issues Aviation Safety Recommendations for Flight Recorder Duration and Power Supply (5 pages)
Apr 08, 1999 About 88 per cent of the MD-11 structure, by weight, has been recovered. About 33,000 pounds of aircraft debris have yet to be recovered. SR-111 13 minute comms gap puzzling.

Nov 18, 1999 Location of Debris Field  defined
Dec 15, 1999

Wreckage Recovery Completed. Suction dredge ship "Queen of the Netherlands" brought to the surface 8 500 cubic metres of material. Total weight of aircraft wreckage recovered is over 127 090 kg or about 98 per cent of the original structural weight of the aircraft.

May 24, 2000 20 arced electrical wires have been found. Work is ongoing to see if it is possible to distinguish between wires that arced because of damage from an external heat source (ie damaged by a fire), and arcing in a non-fire environment.
