## Summary

This document proposes to revise AD 94-07-10, which currently requires the following on Fairchild Aircraft SA226 and SA227 series airplanes: repetitively inspecting (visually) the wing skin for cracks; dye penetrant inspecting the spar straps if the wing skin is found cracked; and, if any crack is found in the spar straps, repairing the spar straps and modifying the wing skin. That AD references an incorrect dye penetrant inspection when the wing skin is found cracked. This action would maintain the requirements of AD 94-07-10, but would incorporate the correct dye penetrant inspection for when the wing skin is found cracked. The actions specified by the proposed AD are intended to prevent failure of the wing skin at the top aft outboard corner of the battery box, which could result in structural damage to the wing.
