Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model 717-200 airplanes. This proposal would require a general visual inspection to detect corrosion of the left- and right-hand horizontal stabilizer hinge fitting bolts, barrel nuts, and the associated holes in the horizontal stabilizer structure, and to detect corrosion of the left- and right-hand elevator sector pinch bolts and associated holes, as applicable; and corrective actions, if necessary. This action is necessary to detect and correct corrosion of the left- and right-hand horizontal stabilizer hinge fitting bolts, barrel nuts, and associated holes in the horizontal stabilizer structure, and the left- and right- hand elevator sector pinch bolts and associated holes, which could lead to loss of a hinge fitting and reduced structural integrity of the horizontal stabilizer. This action is intended to address the identified unsafe condition.
