Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model MD-11 airplanes. This proposed AD would require revising the cable connection stackups for mid-cabin terminal strips, replacing the terminal strips, and removing a nameplate, as applicable. This proposed AD also would require an inspection for arcing damage in the mid-cabin area, and corrective actions if necessary. This proposed AD is prompted by an incident in which arcing occurred between the power feeder cables and support bracket of the terminal strips. We are proposing this AD to prevent arcing damage to the terminal strips and damage to the adjacent structure, which could result in smoke and/or fire in the mid-cabin compartment.
