The aircraft was landing at night on runway 11C, at the end of a multi-sector cargo flight. Weather conditions were fine and clear with a light wind from the north-east. The pilot said the touchdown was normal. However, the aircraft started to pull to the right, the right tyre deflated, and the right main landing gear collapsed. Skid marks on the runway were consistent with the right wheel being locked from about 400 metres beyond the landing threshold. The skid continued for a further 124 metres, parallel to the centreline, before the right tyre deflated. The skid continued for a further 151 metres before the right main landing gear collapsed, resulting in the aircraft departing the runway to the right. A subsequent examination revealed no mechanical fault with the wheel brakes or wheel bearings. Evidence was found which was consistent with an excessive application of the right brake.
