## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Boeing Model 747SP series airplanes modified by supplemental type certificate ST09097AC-D. This proposal would require modifying the passenger entertainment system (PES) installed by that STC and revising the Airplane Flight Manual. This action is necessary to ensure that the flight crew is able to remove electrical power from the PES when necessary and is advised of appropriate procedures for such action. Inability to remove power from the PES during a non-normal or emergency situation could result in inability to control smoke or fumes in the airplane flight deck or cabin. This action is intended to address the identified unsafe condition.
