Work in progress

The thread on the axis of the emergency change-over at the main engine was damaged so the nut could not be fastened. 
That part of the engine was not working properly so it had some maintenance last week, but it was not possible to fix the nut anymore. So we fixed the thread with a small file.... 
So far so good.
And we tested the last pair of fuel injectors and replaced a starting air valve. 
All on the day before Christmas.
