“The ATSB reviewed the damage to the aircraft and found that the nose gear did not sustain a fracture through any of the major structural components (i.e. the nose gear strut or fork), but had deformed rearwards, under the aircraft. For this to have occurred, the ground clearance must have been sufficiently reduced so that the nose gear strut or fork made contact with the runway, imparting significant forces on the gear assembly and initiating the damage sequence.
The factors that affect the ground clearance during landing include the tyre pressure, engine weight, runway condition and dynamics of the landing. In this accident, the exact mechanism by which the gear made contact with the runway was not determined.”
