This amendment adopts a new airworthiness directive (AD) that applies to certain Fairchild Aircraft SA226 and SA227 series airplanes. This action requires 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. This action also provides the option of modifying the wing skin as terminating action for the repetitive inspections. Reports of wing skin cracking because of repeated bending of the wing during service on several of the affected airplanes prompted this action. The actions specified by this 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.
