From what I have read, there were maintenance concerns, but the primary concern was Pilot proficiency. This Plane Talking blog by Ben Sandilands makes interesting reading
Hmmm, from Plane Talking:
Why the Tiger flight first attempted its landing with a tail wind component when for a few minutes additional time in the air it could have made a conventional landing into the wind will no doubt be explored by the ATSB.
The above quote is maybe an indicator of the level of ingnorance by some commentators. The wind on approach and the wind on the ground are not the same thing. It is quite normal in some places to experience 20-30 knots tailwind on approach and with the risk of getting high despite the wind on the ground being VRB/5!
