If the LEFT engine failed or failed first (i.e. in the event of dual engine failure) it is probable that the aircraft would have initially yawed to the LEFT..possibly as far as 30 deg LEFT of the centre-line of Runway 17. Again, if the problem was engine failure and/or the auto-feather system did not function correctly or quickly enough, the pilot may have been looking to put the aircraft back down on the ground, instead of conducting a single engine climb and recovery back to the field. There is very limited space on the eastern side of Runway 17, so he may have initially aimed at Bulla Road, which would have been directly to his front. However, he either lost control very late in the descent and veered into the Direct Factory Outlet (DFO) and/or Bulla Road was occupied by heavy morning vehicle traffic, so he may have had no option - but to put down on the roof of the DFO, which is located between Runway 17 and the airport boundary.
