Re blacksheep
Yes your absolutely right,
all flying controls must be re balanced and checked to enable a CRS (certification of release to service).
But the aircraft does not in all cases have to be re weighed,
this is for the engineer to decide if he sees fit.
This was spoken to me by a member of the CAA.
In all the aircraft i have been involved with painting, (and im talking hundreds) none had to be weighed before release to service
But does it vary in diffrent areas of the globe?.
This i dont know
I couldnt very well tell everyone the life story on aircraft painting now could i blacksheep?.
If i had then this post, should have been opened and closed in one foul swoop, after all im offering my service to whoever needs advise, and if idont know i will try my hardest in finding the answer
cheers
