Chapter 09 – Landing Gear (Gear Leg Fairings) – 30 Hrs

Landing Gear Fairing SegmentPut the gear back on the fuselage and propped it off the ground with a 2 degree up attitude and leveled side to side.  I had purchased the pre cut cores from Eureka for this, and while a discussion on the forums discussed only needing 2 ply for these, I noticed that the foam that is used is the hardware store variety made by Dow.  Since this foam is much smoother than the foams we use normally, I was worried about Landing Gear Fairing Segmentdelamination, so I decided to also use 3 layers of BID to cover.  I removed the cores from the foam and cut into 2.5″ sections, making sure to label everything with Pilot/Copilot side, Top/Bottom, and 1-13 starting at the top of the gear leg.  Dropped a center line for the fuselage and used that to verify the fairings were aligned left to right, by dropping lines off the front and aft corners.  Also used a water level to be sure the fairings will be level when at a 2 Landing Gear Fairing Segmentdegree up attitude.  Micro’d these onto the gear leg, but used 5 Min epoxy/micro mix in the center of each so I could keep attaching sections.  Once both sides were done and all the micro cured, I started sanding the foam to remove the high spots.  Since the foam doesn’t bend around the gear leg perfectly.  Then proceeded to micro and fill the low spots and cracks with micro and glass with 3xBID.  Removed peel ply and trimmed after cure.

Turned the fuselage over and prepped the surfaces for a 2xBID tape around the LG bulkheads.  After taping, added peel ply to finish.
