1.12.11  Examination of Flight Crew and Passenger Seats

  1. 1.12.11.1 - Flight Crew Seats
  2. 1.12.11.2 - Passenger Seats

1.12.11.1  Flight Crew Seats

The seat belts from the captain's seat (STI1-83) were not fastened at the time of impact, and the seat was in the egress position. (STI1-84) The seat was broken away at the time of impact by a force having a vector component acting from right to left. There was no clear indication regarding whether the seat was occupied at the time of impact.

The first officer's seat, (STI1-85) which had broken away from its support, was facing forward in a normal flying position, and the seat belts were fastened at the time of the impact. (STI1-86) The seat was occupied at the time of impact.

The right observer's seat, (STI1-87) which had broken away from its support, was facing forward in the fully aft and fully left position at the time of impact. The seat belt was unfastened. (STI1-88) It could not be determined whether the seat was occupied at the time of impact.

Light yellow-coloured regions were found on the cockpit sheepskin seat covers. Microscopic analysis revealed that this discolouration was created by the presence of countless small tufts of light yellow fibreglass particles, which were embedded and intertwined in the grey wool fibres of the seat covers.

1.12.11.2  Passenger Seats

The passenger seats sustained a high degree of impact-related damage; therefore, identification and reconstruction of individual seats was not possible. The extent of the damage also prevented any determination of whether any particular seat was occupied at the time of impact.
