This could be why they don't mention it or call a mayday until the IDG's and engines start to fail later in the go around due to the damage sustained.

Another logical assumption emerges by one A320 pilot:-
L/Gs were down during 1st attempt. G/A was opted to avoid runway overshoot due to high altitude approach from very beginning, Flaps selection to position 3 from 4 and Gears Up selection was too early, which caused acft to sink and engines rubbed the runway, got damaged and packed up during GA to 3000 ft, acft couldn't hold 3000 ft due to dual engine failure,
RAT deployed automatically to provide emergency elect and prssurise Blue Hyd circuit to power Flt Controls, but due thrust loss acft descended to 2000 ft, that's the time pilot reported Mayday Myday--- aircraft crashed short of Runway by 1300 meters on residential area.
