Empennage

Elevator  (3.5 hrs )

Big day today....joined Front Spar with Tips to the Skins, etc. It's been a long journey for the Elevators (seems as long as the Rudder + Vert Stab + Horiz Stab combined...)  
Bottom side LH Elevator...Front Spar installed.  "Stored" while work on RH side...
Sect 9-20, Steps 7-9: Riveted LH and RH Front Spar Assly's into Elevator Skins at Ribs with 18 blind rivets each side.  Very satisfying to have perfect alignment of all holes.

Sect 9-21, Steps 6-8: jumped one set ahead to complete Inboard Close-out of RH Elevator, since already on the table.  Tricky 2 rivets to E 921 Gusset - requires lifting corner of skin to reach shop ends.  My wife's smaller hands were really helpful.  Thanks Nancy !  
RH Inboard Close-out...done
 Steps 1-5:  Back up one set of instructions to do LH Elevator Inboard Close-out.  Again, several challenging rivets requiring lots of patience.   But each time figured out best way to position bucking bar (even one time able to use Main Squeeze to reach inside).  

Started Sect 9-22, Step 1 and Step 5 riveting Shear Clips to LH and RH Outboard Tips.   Tiring work today due to many different set ups and tools, and lots of reading and re-reading to be sure understood instructions and process expected.
