The stiffeners on both main landing gear doors were replaced, left and right, on a Cessna 560XL Citation XLS+.

Runway debris and de-icing salt had chipped the paint along the stiffeners, and corrosion had taken hold on and around the rivets. The main gear doors sit in the spray thrown up by the wheels, so they take the worst of both.

The replacement stiffeners were fitted to the existing fastener pattern and riveted along the full length of each door.
