Repairing Major Damage: - Larger Than 1 Inch In Diameter - Piper Malibu Meridian PA-46-500TP Airplane Maintenance Manual

E. Repairing Major Damage: - Larger than 1 inch in diameter (See Figure 6.)
(1) If possible, a patch should be made of the same material, and cut slightly larger than the
section being repaired.
(2) When appearances are important, large holes, cracks, tears, etc, should be repaired by cutting
out the damaged area and replacing it with a piece of similar material.
(3) When cutting away the damaged area, under cut the perimeter and maintain a smooth edge.
The patch and/or plug should also have a smooth edge to ensure a good fit.
(4) Coat the patch with solvent adhesive and firmly attach it over the damaged area.
(5) Let the patch dry for approximately one hour before any additional work is performed.
(6) The hole, etc, is then filled with the repair material. A slight overfill of the repair material is
suggested to allow for sanding and finishing after the repair has cured. If patching compound is
used, the repair should be made in layers, not exceeding a 1/2 inch thickness at a time. This
will allow the compound to cure and ensure a good solid buildup of successive layers as
required.
