## Summary

We propose to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-10-10, DC-10-10F, and MD-10-10F airplanes. This proposed AD would require a one-time high frequency eddy current inspection of fastener holes for cracks at the left and right side wing rear spar lower cap at station Xors=345, and other specified and corrective actions if necessary. This proposed AD results from a report of three instances of Model DC-10-10F airplanes having fuel leaks in the wing rear spar lower cap at station Xors=345. We are proposing this AD to prevent cracks in the spar cap, which if not corrected could lead to cracking of the lower wing skin, fuel leaks, and the inability of the structure to sustain limit load.
