Is the dispute only over money? The OP indicated the work was to be done in 2 months and is going on 6 months now (post 8). So it's not complete. I don't know, maybe a little more to the story.
Not certain, but I think it's an AOA...Aircraft Operating Above. Now if this AOA doesn't have An Operable Approved AOA, it could crash. So, if you see it again, be very careful (assuming of course it hasn't crashed already).
