Assuming APU not operating, that might take them straight from full electrical power to battery power only - another unwanted distraction.
Are all the FADEC systems sufficiently clear of the cowling scrape area to avoid damage?
Damage caused by the scrapes might be a slow train wreck rather than fully apparent.
With gear already up, the crew might have intentionally selected less than TOGA for the go-around, which could have been a significant contribution to the end result
Regarding the question on FADEC systems being sufficiently clear of the scrape area.
The FADEC's dedicated alternator, High Pressure Fuel Pump are both on the main gear box (MGB) that on the -5B is on the lower side of the engine. If the engines had impacted the ground hard enough it's not hard to conceive the whole MGB was compromised that would not only render the IDGs inoperative but also the other accessories on inlcuding the Engine Fuel Pump, FADEC dedicated alternator as well as the Hydraulic pump with no chance of recovery. In addition to this fuel lines, hydraulic lines for Yellow/Green systems would have probably been compromised on the engines too.
