Brief Description: Rear Fuselage Top Skin & Rear Fuselage Assembly
|
|
Install the opposite Side Skins using the same procedures used to install the first side.
Cleco the Longerons on to the top of the Side Skins.
Cut two L angles to fit between the Side Skins at the top of the H.T. Frames. Clamp the L angles to the Longerons and the H.T. Frames. With a #40 drill bit, back drill through the H.T. Frames into the L angle and Cleco. With a #20 drill bit, expand the holes in the H.T. Frame and L angles and Cleco.
Cleco the Uprights and Side Channels to the Side Skins.
Cleco the Rear Top Channel Angle to the Rear Top Channel. With a #30 drill bit, expand the holes on the aft flange and Cleco. In the photo above, the aft flange is the flange with the two Clecos installed. Then with a #20 drill bit, expand the holes. Leave the holes in the top #40 until they are installed on the Fuselage.
Cleco the Top Channel to the Rear Top Channel. The Rear Top Channel fits inside the Top Channel. Use a #30 drill bit to expand the holes, then a #20 drill bit to expand the holes and Cleco.
With a hacksaw, trim the excess Longeron off flush with the edge of the Side Skin. Cleco the Rear Wing Attachment to the Side Channel and the Top Channel to the Rear Wing Attachment. This will support the Side Skins and help square the Rear Fuselage. Use a #30 drill bit, then #20 drill bit, and finally a #12 drill bit to expand the holes in the Rear Wing Attachment and Cleco.
Position the Top Skin on the Rear Fuselage. Cleco the Top Skin to the Top Channel. With a #40 drill bit, back drill through the Top Skin into the Longerons. Start at the front and work aft and Cleco every third hole. With a #30 drill bit, expand the holes through the Longeron. Wait to drill the holes common with the Top Doubler.
Check: Make sure the Top Skin is against the lip on the Longeron and not on top of the radius of the Longeron.
