Horizontal Stab - Part IV

Have not posted in awhile, and been busy on a number of fronts:  being sick, kids being sick, snow, cold temperatures, etc - all has slowed down progress - but not completely!

So everything has been drilled, cleaned, alodined, and primed.  I had to wait for a high single digits day (degrees C) to get all this done - but it is DONE!.

Since last post, I drilled the spar caps that tuck into the U shape of the spar:




Everything has been alodined and primed:




The spar webs have been riveted into place, alone with the aft spar attach bracket (had to order one, as my kit seemed to be missing this part)









The nose and main ribs have been riveted into place (thank is a big part to my 'helper').




Next steps:

- Fit skins, and check the cutouts on the bottom for the forward and aft attach brackets.
- Rivet the bottom of both skins, leaving the nose ribs and main structure exposed and ready for inspection.

Unfortunately (or fortunately, depending on your viewpoint) I cannot completely close up the structure until it has been inspected (Canadian regulation).  My MD-RA 'letter of intent' has been sent  in, and I need to request inspection of all the tail components.  Will do this after the elevator is ready for inspection - that way the inspector can do all 3 in one $435 dollar job...

My 'helper' has been bugging me already today "are we going to work on the airplane tonight"?  So hopefully we will start riveting tonight assuming everything fits as it is supposed to...
