Earl,
To take the engine in the shop and do the mod takes about 8-10 days including test.
However the mod only affects the 02 module so you can put a spare 02 module in the shop and do the AD on the module.
Then you just swop the modified 02 module and they can so in 2-3 days.
I just talked to a buddy in Amman and he says that the Luzair L1011 is still there clearing some snags.
How is your ATA thing going ? My buddy in Amman did not know about it going there.
