Required Actions
Inspect the inboard and outboard aft attach lugs of the left and right elevator control tab mechanisms for gaps between the swage ring and the aft attach lug, and between the spacer and the aft attach lug. Try to move or rotate the spacer using hand pressure. Replace any discrepant elevator tab control mechanism, including performing the detailed inspection on the replacement part before and after installation.
