Jan 20, 2024 1.5 Forward flying wire issues Category: Rigging
It's been miserably cold and windy around here the last week or so and not so fun to go warm up the hangar as it takes forever.
Did however remove the forward flying wires which are coming up a bit short. Yup, I need to make new attach tabs a bit longer. The threads were just short of the witness holes in the end terminals. Comparing the bolt-to-bolt dimensions of the tab attach bolts to the pin-to-pin dimensions of the forward flying wires (103.75" vs. 100.5") leaves a difference of 3.25". Divided in half for each end means each tab should require 1.625" or 1-5/8" from the C/L of the attach bolt to the C/L of the terminal attach pin hole. Further working that out, the center insert tab needs to be 1-15/16" long and the outer wrapper length is calculated from Murray's analysis (2 X Tab length + 1.33" to wrap around a 7/16" tube) comes out to be just a smidge over 5.2".
So, I'll re-make the attach tabs to the new lengths, but I don't think they'll be noticeably longer to the eye. Unless compared side by side with the originals.
These should result in a pin-to-pin dimension of the installed wire at 100.5" which leaves plenty of length for adjustments in either direction.
