Well the ATSB report states that they commenced the go-around due to being incorrectly configured and DURING the go-around, the EGPWS alert of 'too low gear' sounded. As far as I'm aware the EGPWS alert 4A only goes off below 500'AGL and at a speed of less than about 160kts. As the report states that this alert sounded, they must have ducked below these qualifiers during the go around and not commenced the go around due to the EGPWS gear alert. From memory though, a 'too low terrain' alert should have sounded before the 'too low gear' alert somewhere between 1000-500AGL (dependent on their IAS)?
Hard luck lads, thoughts are with you. Hope the report shows it to be favourable in your direction as any of us could be caught in this situation with the right combination of factors.
Cheers
