Corrosion was found at the flap hinge fairing on a Cessna 525B Citation CJ3. The fairing was removed and replaced.

With the fairing off, the hinge area and the attachment flange were cleaned back and assessed. The replacement fairing was offered up and held in position while the fastener pattern was matched to the existing holes, then riveted out.

The new fairing was installed in primer and the area cleaned and inspected on completion.
