Step 1 : A/T Off immediately
Step 2 : Slow down at least with flaps 2 and F speed
Step 3 : Never trim and use manual thrust simultaneously, make a small trim change and wait to see aircraft response, make a change in thrust and wait to see aircraft response, but don't do both at the same time.
Step 4 : Configure early and request long final.
Step 5 : Hope for the best!
Cheers!
