Empennage Fairing ( 4 hrs )
Trimmed Empennage Fairing to within 1/8" scribe line per Sect 12-10, Steps 1 & 2. Retrieved from storage the Horiz Stab and Vertical Stab to mount to Fuselage. Added Emp Gap Covers F12111 L & R. Since Fairing is opaque due to primer/filler coating, I marked center-line of nutplate holes along Fuselage, HS, & VS - including mark at 50 mm distance. Will use to transfer hole center-line to Fairing when drilling (vs light inside which would required sanding off coating at each location, OR using the spherical magnets). Per Steps 3-5 at Sect 12-10, I did many iterations of marking interference at leading edge of VS and HS, then grind/sand some...repeat. I eventually achieved good, tight fit.

trimmed excess...leaving 1/8" at scribe line |
 |
temporary mounting HS and VS |
 |
marked line from centerline nutplate holes, with cross mark at 50 mm. Will allow accurately locating blind holes to drill |
 |
first pass... interference at VS preventing Fairing from contacting HS leading edge...but close |
 |
after several iterations of grinding/sanding inside Fairing, getting good fit around all leading edges |
 |
good fit at VS leading edge |
