Wreckage Reconstruction
There are three activities related to the wreckage reconstruction; the 2D hardware reconstruction, the 3D hardware reconstruction, and the 3D software reconstruction. The 3D software reconstruction was in-charge by lab and 2D hardware reconstruction and the 3D hardware reconstruction all in-charge by investigation division.
2D Hardware Reconstruction.
In order to provide effective and systematic examination of the recovered wreckages, and to assess the possibility of the structure break-up sequence of the CI611 flight, a 2D hardware reconstruction was conducted at the Hanger #2 of the Taoyuan Air Force Base (TAFB). The 2D hardware reconstruction was based on the wreckage distribution of the aircraft as shown in Fig. 1 Only the wreckage parts of Section 46 were reconstructed according to its station number and stringer number of the original aircraft. The centerline of the aircraft belly was served as the center line of the 2D reconstruction on the floor of Hanger #2. The forward of the aircraft was facing the front door of the hanger and the wreckages were laid symmetrically along the centerline. The 2D hardware reconstruction is shown in Figure 2

1.16.3.2 3D Hardware Reconstruction
The objective of the 3D hardware reconstruction is to provide the investigator a 3D prospective of the size and shape of each wreckage pieces relative to the other, to examine the overall force distribution as the break-up of the aircraft took place, and to provide a visual environment to the investigators for the understanding in the relationship of the wreckages as the break up of the aircraft occurred. The 3D reconstruction started from station 1320 to the end of the pressure bulkhead, which covers part of the Section 44, the entire Section 46, and part of the Section 48. There are a total of 34 pieces of the recovered wreckages been posted onto the scuffle. This project started from the end of 2002 and accomplished on April 17 2003. The 3D reconstruction process as shown as following figures.
