RV-9A: Project Entry

Torqued on the vent tube fitting and applied proseal
According to the torque setting instructions in the "5P ALUMINUM TUBING" section of the instruction manual, the torque setting for 1/4 inch tubing is 40-65 inch-pounds, and for 3/8 inch tubing it’s 75-125 inch-pounds. I set the final torque setting after checking a Torque Wrench Extension Calculator for recalculating torque setting when using an extension (in my case a crows foot extension).
