In parallel to the MSN1 resuming the flight tests in the first weeks of August, the second flight test aircraft—MSN3—will be moved to the painting shop and to the station 20 for the engines installation.
I'm a bit confused as to why it's taking long for MSN003 to join the test fleet. It was structurally complete before MSN001 took first flight. And MSN001 didn't take this long to get engines, the paint and move onto first flight after that stage.
As long as MSN3 is inside station 30, it is not structurally complete. And assembly of MSN3 is not taken as long as you think, I count 8 months between FAL start and first flight versus 10 months for MSN1.
