Airworthiness Directive · Amendment 39-12323 · Boeing Model 737-700IGW Series Airplanes Modified by Supplemental Type Certificate ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D
Boeing Model 737-700IGW Series Airplanes Modified by Supplemental Type Certificate ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D
Model 737-700IGW series airplanes modified by Supplemental Type Certificate (STC) ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 737-700IGW series airplanes modified by Supplemental Type Certificate (STC) ST09100AC-D, ST09104AC-D, ST09105AC-D, or ST09106AC-D. This AD requires modifying the passenger entertainment system (PES) installed by those STC's 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.
