6、) requirements. Since its approval, ARP6199 has not been utilized by all OEMs, as originally envisioned. The previous version of ARP6199 required more clarity and some modification to be harmonized. This version presents an updated common criteria for determining which panels on the seat must be eva

BACKGROUNDIn 2007, the FAA released

28、 special conditions that held seats to the same heat release and smoke density standard as the rest of the cabin. EASA soon followed with similar regulations. The seat HRSC require heat release and smoke density tests for large, exposed, non-metallic, non-traditional panels that are part of the seat

29、 design.In January 2010, the industry and regulators began meeting to develop common criteria that can be used to determine which panels on a seat require heat release and smoke density substantiation. This activity was concluded in December2010 and the final criteria were subsequently distributed t

30、o all of the industry and regulatory participants.The following assumptions and ground rules were used in developing this certification approach:xWhen 14 CFR part 25.853(d) was added in the late 1980s, seats were exempted from the rule. It was accepted at that time that there was a certain amount of

31、 non-metallic material as part of seat design. It is understood that the Seat HRSC are intended to capture the increase (or delta) from that baseline to seats today.xWhen determining “traditional” envelopes for different zones on the seat (e.g., center consoles, end bays, etc.), the collective exper

32、ience of the industry determined reasonable estimates based on a variety of examples from seats of the mid-to-late 1980s era.xIt is assumed that there is some flexibility to meeting the Heat Release and Smoke requirements where safety-related items may not meet HRSC and also perform their basic func

33、tion. These can be coordinated with the regulators on aproject-specific basis.xThe requirement to test seat panels to the Heat Release and Smoke requirements does not include a requirement to test to 60-s vertical burn (14 CFR part 25 Appendix F, Part I (a)(i). TC/STC/ATC holders and suppliers can e

34、lect to step up to this requirement voluntarily.xSeats are evaluated in the TTL position.SAE INTERNATIONAL ARP6199A Page 6 of 344. SEAT CERTIFICATIONThe following tables summarize when compliance must be shown at an aircraft installation level by the installer for Heat Release Special Conditions. Th

35、is takes into consideration that the certification of a seat may be based on a similar seat that was previously certified, or may be a new, stand-alone certification.Table 1 - New production (line fit) programsNew CustomerSame Customer, New A/C Model(new family or newderivative)Same Customer, NewBlo

36、ck of A/CSame Customer, SameBlock, New seat countSame Seat P/NNew Seat P/N,no change tolarge panelsNew Seat P/N,changes to largepanelsNew SeatModel= seats must be shown compliant with Special Conditions1. “New Customer” relates to a situation where Airline “A” has, for example, Model “X” airplanes c

37、ertificated with seats with large non-metallic panels prior to the issuance of special conditions. Airline B, after the effective date of the special conditions, purchases Model “X” airplanes and may (or may not) have exactly the same seating configurationas Airline “A.”2. “Same Customer, New A/C Mo

38、del” means if Airline “A” has, for example, Model “X” airplanes certificated with seats with large non-metallic panels prior to the issuance of special conditions. The Airline now purchases Model “Y” or Model “Z” airplanes and installs seats in the new Model “Z” after the issuance of the special con

39、ditions.3. “Same Customer, New Block of A/C” means if Airline “A” has, for example, Model “W” airplanes certificated with seatswith large non-metallic panels prior to the issuance of special conditions. The Airline now purchases, after the effective date of the special conditions, additional Model “

40、W” airplanes.4. “Same Customer, Same Block, New seat count” means if Airline “A” has, for example purchased 50 Model “V” airplanes and the first of this block of 50 airplanes has been type certificated with seats with large non-metallic panels prior to the issuance of special conditions. Then on the

41、 15th airplane to be delivered (which is after the effective date of the special conditions), the Airline decides to increase the number of first class seats in the airplane and reduce thenumber of economy class seats.5. “Same seat P/N” means a seat that is unchanged. In the case where the same P/N

42、is retained, but changes are madeto all seats with that p/n (i.e., the prior configuration is eliminated on the drawing and in the field), this is considered as“New” for the purposes of implementation of the special conditions.6. “Customer” refers to the end user, and not a leasing company, that sup

43、plies many operators.SAE INTERNATIONAL ARP6199A Page 7 of 34999999Table 2 - Post-TC modifications (retrofits)Installation of existingarrangement for fleetcommonalityRe-arrangement (orremoval) of existing seats(no additional seatinstallations) New installation of seatsSame Seat P/NNew Seat P/N, nocha

44、nge to largepanelsNew Seat P/N,changes to largepanelsNew Seat Model= seats must be shown compliant with Special Conditions1. “Same,” or “new” with respect to seat P/N refers to authority approval status, and whether there is an installationapproval, even if it was granted to someone else. The applic

45、ant is responsible for both identifying and supplying evidence of the prior approval2. “Fleet commonality” means the installer already has this arrangement in their fleet, and is configuring other airplanes to match. Modification is being performed by other than airframe manufacturer.3. “Re-arrangem

46、ent” means the seats are moved around, or maybe some are removed, but no additional seats areinstalled.4. “New Installation of seats” means that the modification includes installation of more (Table Row 1) or different(Table Rows 2 to 4) seats than the current arrangement. Includes both a new instal

47、lation as well as adding to anexisting arrangement.5. With respect to Table Row 2, Column 3, when the same operator/user obtains a post-TC approval (e.g., viaSTC) to essentially provide fleet commonality with the arrangement as delivered from the factory, R2:C1 would applyinstead. Where a customer/u

48、ser is obtaining a new installation approval for a new P/N, which happens to be similar toanother customers approval, the special conditions would apply.-,SAE INTERNATIONAL ARP6199A Page 8 of 344.1 Meeting the Test Requirements of 14 CFR Part 25 Appendix F, Parts IV and VDetermining the parts to be
