7 March 201 3 Y. Regis Head of Product Integrity Airbus 1 Rond - Point Maurice Bellonte 31707 Blagnac Cedex, France 31707 Dear Mr. Regis : We received your petition (M13003411) dated 11 February 2013, on behalf of Airbus, requesting exemption from Ti tle 14 , Code of Federal Regulations ( 14 CFR) 25. 813 ( e ) at Amendment 25 - 116 and 14 CFR 121.310(f) (6) . You requested this exemption to install “mini - suites” in the Airbus Model A321 for Jet Blue Airlines, a U.S. operator . This request, which you submitted to the Department of Transportation’s Federal Docket Management S ys tem , has been given Docket No. FAA - 20 13 - 0189 . We have reviewed your petition and have determined that more information is needed before we can process it . Please resubmit your petition addressing the following issues to the Federal Docket Management Sy stem Docket No. FAA - 2013 - 0189. 1. The petition requests exemption from § 25.813(e) at Amendment 25 - 116. The correct Amendment level of this regulation for the Airbus Model A321 is Amendment 25 - 46 as shown in Ty pe Certificate Data Sheet No. A28NM . The requirements of § 121.310(f)(6) do not affect the Amendment level of § 25.813 in the certification basis for the airplane . Airbus will need an exemption from § 25.813(e) at Amendment 25 - 46 to support installation of the mini suites. Please revise your request accordingl y. 2. The petition requests exemption from § 121.310(f)(6). An exemption from § 121.310(f)(5) i s also required. Please revise yo ur request accordingl y. 3. Please provide a plan v iew of the proposed aircraft interior arrangement and side views of the mini - suites when viewed from inside and outside the suites. 4. Item 13 of the “Supporting Argumentations” section notes a second path out of the mini - suite is provided. Please describe this second path . 5. The “Supporting Argumentations” section states, in part, “ ... the design precautions implemented on these mini - suites are in line with the ones certified on previous2

mini - suite installations.” And a note on the last page states , “Similar e xemption has already been granted for very similar mini - suite installations. See Boeing 777 EL OS (PS05 - 0272).” With regard to the Boeing 777 equivalent level of safety ( EL OS ) findings , an additional flight attendant, above the minimum required by the operating rules, was also required. The additional flight attendant’s principal duty is to ensure the mini - suite doors are “latched” in the open position for taxi, takeoff, and landing. Please revise the request accordingl y. 6. Item 21 of the “Supporting Argumentations” section notes the passenger seat modules will not exceed 25% of the maximum number of passenger seats allowed between the doors , as defined in the A321 ty pe certification. We were unable to find the maximum number of passenger seats allowed between the doors b y reviewing the type c ertificat e data s heet. Please specify the maximum number of mini - suites to be installed between the fuselage doors. 7. The “Public Interest” section specifies why granting this exemption is in the interest of passenger s and operators but not the public as a whole. Please revise the “Public Interest” statement accordingl y. When we receive the re quested information, a s ummary of your petition will be published for comment in the Federal Register for a 20 - day comment period, in accordance with the requirements of § 11.89. You will be advised of the agency ’ s decision on your petition as soon as possible after the comment period closes . We also need to make yo u aware that the Transportation Security Administration (TSA) h as required the removal of curtains that separate the different parts of the passenger cabins because of security

concerns a fter the events of September 11, 2001 . TSA has allowed curtains that separate the galley area from the passenger area. One of the reasons they allow these curtains is that crew members occup y the galley area and not passengers. At this time it is unclear if TSA will accept the doors installed on these mini - suites. If we do not hear from you within 30 days, we will close the project without notifying you further. In the meantime, if you have any questions or concerns regarding your petition or the petition process, please contact Dan Jacquet at 425 - 227 - 2676 or at daniel .jacquet @faa.gov.
