the rumor I heard was not A319's but 32 A320-232's all from China with the V2527-A5 engines.
The Hold-up as I heard it were the A.D notes and Mods to communize them with our own airplanes. These -232's have a lightly higher Max ZFW and Max Landing weight than our-231's and the ACARS, GPWS mode 5-7 with TAWS has yet to be installed.
The FAA CMO out of San Francisco seems to already be in the loop...
Now? There could BE more A319's for all I know but the A320-232's is what I heard and more than ONCE. And I'm particularly interested as I will be in the Group handling them on the TOMC Airbus desk. As Well as the A350.
