A very good job !
Just how much uninformed rubbish can this forum generate ?
The bottom line is the crew got the aircraft on the ground and no one was hurt.
Objective achieved !!!!!!
In my veiw ( as a 737 & A320 type rating holder & former holder of CRS maintenance approval on the A320) the guys did a good job and as well as could be expected with the information that was unfolding to them over the time of the problem.
The pre-flight could have picked up the problem but, the system is not encouraging pilots to give more than a quick glance around the outside, in the UK you can't have any form of personal tooling and so my very usefull screwdriver is unavailable to me thanks to the security system.
I have to ask the Monday morning quarterbacks what do you expect the crew to consider when they have a problem? As far as I can see the guys acted correctly when in a high workload situation with the information that they had avalable as events unfolded.
