Engine run #2 and Tailcone Fairing

Reinstalled the coolant elbow and hose.  Refilled the coolant and test ran the engine.  No leaks detected!  Score!

I then turned to working on this tailcone fairing again....

I sorta followed the KAI's by cutting and fitting the two parts of the fairing together and drilling the screw holes that will hold them together.


I then used my nutplate jig to drill for the nutplate mounting rivet holes.

And installed the nutplates.  Hopefully my days of installing new nutplates are about done.  There must be a million of these things in these airplanes. 


I then countersunk the screw holes for the flush #6 screws.

Put the two parts on the airplane and screwed them together.  This starts to show just how much of a blast fitting this thing is going to be!  I decided to go ahead and rough cut the slot out for the AST/Trim tab pushrod.  Not sure how one could wait longer to do this and get everything centered.


Just be aware that the directions are kinda wonky, the scribe lines are wonky, and the mold seams are not in the center of these parts.  It takes a ton of put it on and mark stuff and take it off and trim iterations.  I must have done this a hundred times.
