The surface tear can be analyzed the same as any other opening in a continuous diaphragm..the opening must be able to distribute the forces around the opening.
The affected members at the 'opening', may need reinforcement to distribute, without wholesale replacement.
With the skin or diaphragm, that is a mere function of the fastening in regards to continuous, so perhaps a different fastener schedule about the affected area.
This event was an impact, so as long as there hasnt been deflection (bending) in the members, there can be no justification for replacement of the wing structure.
others comments..no, no, and no, a new wing is NOT required...if above.
You dont replace your arm if you have a cut.
