Airworthiness Directives; McDonnell Douglas Model DC-8 Series Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-8 series airplanes. This proposal would require detailed visual and eddy current inspections of the lower wing skin at the 3 outboard fasteners of the stringer 64 end fitting to detect cracks; and corrective actions, if necessary. This proposal is prompted by reports of fatigue cracks found in the lower wing skin initiating from the outboard fasteners of the stringer 64 end fitting. The actions specified by the proposed AD are intended to prevent such fatigue cracking, which could reduce structural integrity and loss of fail-safe capability of the airplane.
