The
Australian Transport Safety Bureau (ATSB) and the Republic of Singapore
Air Accident Investigation Bureau (AAIB) are currently investing an incident when a Jetstar Airways (JST) A321-231 (
VH-VWW) operating as flight number JQ57 was forced to go-around on the 27th of May 2010 after receiving a Mode 4A "Too Low, Gear" aural warning from the Enhanced Ground Proximity Warning System (EGPWS) just 400 feet Above Ground Level (AGL) during final approach.
A flight crew was said to be sending text messages on the short final thus violating the sterile cockpit rule.
