A foreign object, presumably a fragment of the casing of the APU gas collector which was located under the control flap of the starter, entered the engine and sliced the fuel lines, hydraulic lines, and oil lines.
Un obxecto externo, presumiblemente o anaco da carcasa do colector de gas da APU que estaba situado baixo a aleta de control do iniciador, entrou no motor e cortou as liñas de combustible, as liñas hidráulicas, e as liñas de aceite.
