Whilst examining the wreckage in a warehouse, British investigators noticed a spacer was missing from the bogie beam on the left hand main landing gear (it was later found in an Air France maintenance workshop). This skewed the alignment of the landing gear because a strut was able to wobble in any direction with 3° of movement. The problem was exacerbated on the left gear's three remaining tyres by the uneven fuel load. Drag marks left on the runway by the left rear landing wheels show the Concorde was veering to the left as it accelerated towards takeoff.
