Preflight Bolts and Nuts Check

TLDR

• Checked all bolts and nuts on torque tubes

Details

Last week I had a call with Kelso, who is a very experienced Sling test pilot. Kelso offers to test fly the airplane at a service fee. I have not fully decided but I am seriously considering working with him for the first flight.

During the call, Kelso made a good suggestion - check all bolts/nuts on each torque tube especially the elevator torque tubes.

So today I took off all inspection doors and checked all torque tubes:

1. Nothing is obviously loose
2. They all have jam nuts
3. They all have torque seal

I also took a bunch of pictures for archive while having all the inspection doors open.

A few torque tubes are not yet captured: mostly on the control column. I ran out of time today, and will continue to remove skins to inspect the control column tubes.
