What We Did with Pictures
Right Wing Root Damage and Repair
 

This is a close up of damaged area from wing catching door bracket.

This view is of the damaged area in perspective with forward section of wing.

Modified the fabric tear with a hot iron, to prevent further tearing, and replaced the rivet.

Added a second rivet added to hold metal in place and provide additional strength.

Measuring tape is displayed here to provide scale to the modification.

This is a repeat from different angle.

Replaced fabric tape to minimize chafing and added a dotted line to see how far out on wing that paint needed to be removed.

Cleaned fabric with methyl ethyl ketone and polytacked fabric in place.

Ironed patch in steps up to 350F heat. After this picture, I painted with three coats of Polybrush, three cross coats of PolySpray, a coat of white insignia polytone, and two coats of yellow polytone. Note this patch is in a hidden, dark internal spot on the plane and it is backed with aluminum, so no light test is possible after the polyspray coats, nor is it really needed.

Final appearance of patched area.
