## Abstract

The FAA is superseding an existing airworthiness directive (AD), which applies to certain McDonnell Douglas Model MD-11 and -11F airplanes. That AD currently requires an initial general visual inspection of the power feeder cables of the integrated drive generator (IDG) and the fuel feed lines of engine pylons No. 1 and No. 3 on the wings for proper clearance and damage; corrective actions if necessary; and repetitive general visual inspections and a terminating action for the repetitive inspections. This new AD requires the existing actions, and for certain airplanes, this AD requires installation of new clamps on the power feeder cables of the IDG of engine pylons No. 1 and No. 3. This AD results from reports of IDG power feeder cables riding against structure and fuel lines in the No. 1 and No. 3 pylons. We are issuing this AD to prevent potential chafing of the power feeder cables of the IDG in engine pylons No. 1 and No. 3 on the wings, and consequent arcing on the fuel lines in the engine pylons and possible fuel fire.
