## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all McDonnell Douglas Model MD-11 and MD-11F airplanes and certain Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30 and DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, and MD-10-30F airplanes. This proposed AD would require rerouting system 3 hydraulic piping, installing new pipe assemblies and unions, and installing redesigned support brackets for the system 3 hydraulic piping. This proposed AD results from a report of damage to the hydraulic system that occurred when pieces of a ruptured tire from the left main landing gear penetrated the wing trailing edge access panel during takeoff. We are proposing this AD to prevent damage to the system 3 hydraulic piping, which could result in loss of the hydraulic system.
