I'm slightly curious as to why FCA would be shedding AL and retaining AN.... If my memory serves me correct (which I hope it does as I am still relatively young) AL is 6 years younger than AN and has a better history within the AMM/FCA/DP fleet... And hoping that FCA have learned that the older and crapier the A/C the worse the problems encountered (ref G-OOOC now C-FTDV)
Personally I thought the plan was to refresh the 320 fleet - Mostly done Refresh the B757 fleet - Not far off being done and keep AL/N and incorperate them into the new 767 arrivals.... Was that not why they sold the other 767's to SU last year?
I await correction anyway... :o)
