A big day today, this morning I removed the lower skins & made the adjustments I thought were needed for a better fit then primed the mating surfaces of the main spar. GAM & GML both travelled to the highlands to help today, we were able to install the lower skins & the rear spar skin support. Thank you both very much for your help, I'll get PGC to buy you a beer on my behalf. Three ex LAMEs working on the aircraft - almost as dangerous as two captains on the flight deck!
