Wing strut assembly
Today’s mission was to install 4 AN3-16a bolts and 4 tensile nuts and washers. This mounts the lift strut to the front spar, the rear spar has 2 smaller bolts but as the rear spar is a long flat extrusion those took 5 minutes. The front spar is a hollow “D” shape and I had to insert 2 bolts and 2 washer+nuts from the inside. The wrench was taped to a screwdriver and was easy to fit when the boroscope was on, getting the hardware in was way more fun, magnet did the job after some fumbling.

![Tools required, 1/2 wrench, 1/2 crowfoot on 3/8 torque wrench and the magnet-extension tool worked great](https://d3gxvd7rqm4plm.cloudfront.net/john-s/images/6101/wing-strut-assembly-/7f94e30b9ea241ddaaa92fab88345b70_sm.jpg)
