Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This proposal would require an inspection to detect arcing damage of the electrical cables leading to the hydraulic pump terminal strips and the surrounding structure in the wheel well area of the right main landing gear (MLG); and corrective actions, if necessary. This proposal also would require replacement of a certain terminal strip with a new terminal strip, and removal of the applicable nameplate in the wheel well of the right MLG. This action is necessary to prevent arcing damage to the terminal strips and damage to the adjacent structure of the wheel well area of the right MLG, which could result in a fire in the wheel well of the right MLG. This action is intended to address the identified unsafe condition.
