Brief Description: Finish Drilling Firewall, Aux Longerons F-713
Drilled the remaining holes in bottom skin to firewall. Used same technique for stainless. Also drilled the firewall bracket to the skin. Removed #4 rivets one at at time and drilled the left side skin/longeron to the steel firewall brackets. Inserted a cleco in each hole as drilled. Repeat for right side.
Drew cenetrlines on F-713 aux longerons. Had to trim approx 1/4 inch to get a good fit. Made angle on end to match F-704. Bent flat end to match firewall bracket. Used clamps and duct tape to hold the F-713 with centerline showing through skin holes. Match drilled to skin, cleco as I went. Repeat for other side.
