Boeing Model 737-300, -400, -500, -700, and -800 Series Airplanes; Model 747-400 and -400F Series Airplanes; Model 757-200 Series Airplanes; Model 767-300 Series Airplanes; and Model 777-300 Series Airplanes Equipped With Certain Driessen or Showa Galleys or Driessen Closets
This AD applies to Boeing transport category airplanes equipped with certain Driessen Aircraft Interior Systems or Showa Aircraft Industries galleys, certificated in any category; as identified in paragraphs (c)(1) through (c)(5) inclusive of this AD.
(1) Model 737-300, -400, -500, -700, and -800 series airplanes;
(2) Model 747-400 and 747-400F series airplanes;
(3) Model 757-200 series airplanes;
(4) Model 767-300 series airplanes; and
(5) Model 777-300 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing transport category airplanes. This AD requires inspecting to determine if certain galleys and closets are installed, and replacing the spiral wire wrapping of the electrical cables of the galleys and closets with new spiral wire wrapping if necessary. This AD results from testing and reports from the manufacturer indicating unacceptable flammability properties of wire wrapping installed in certain galleys and closets. We are issuing this AD to prevent fire propagation or smoke in the cabin area due to electrical arcing or sparking and ignition of the spiral wire wrapping.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Note 1: For clarification and for the purposes of this AD, the use of the term “galley” also includes the terms “buffet” and “closet” that are referenced in certain service information specified in this AD.
Within 72 months after the effective date of this AD, inspect the galleys to determine if any of the part numbers (P/Ns) installed are identified in the applicable service information specified in Table 1 of this AD. Instead of inspecting the galleys to determine if the P/Ns are installed, a review of airplane maintenance records is acceptable if the P/Ns can be positively determined from that review.
