Dear Mr. Podberesky: whcallaway@zsrlaw.com

We are writing on behalfofKorean Air Lines Co., Ltd. ("Korean") to request approval for seat configuration changes planned tor aircraft covered by Korean's June 3, 2010 equivalent alternative determination ("Determination'') concerning 14 CFR 382.61 (movable aisle armrests). · · ''

... Condition 2 ofthe Determinations requires the Department's prior approval for any seating configuration changes and/or seat dimension changes to be made on any aircraft subject to the Determination's approval. By means ofthis letter Korean requests the Department's approval for plannedmodifications to the business class seats ofKorean's A330-200 Enhanced ("A330-200E") aircraft. More specifically, Korean plans to convert the Prestige Plus 1 business class seats in five A330-200E to Prestige Sleeper2 seats. Korean will utilize conversion kits (consisting of hardware and software modifications) in orderto accomplish this change. In its Determination, the Department approved the Prestige Sleeper seats installed in Korean's B777-300ER, A380- 800, and B787-8 aircraft as equivalent to seats with movable aisle armrests. Korean also plans to

1Details ofthe Prestige Plus seats are set forth in Exhibit KE-5 ofKorean's March 1, 2010 Application for an Equivalent Alternative Determination. 2 Details ofthe Prestige Sleeper seats are set forth in Exhibit KE-4 ofKorean's March 1, 2010 Application for an Equivalent Alternative Detern1ination.

move the fore and aft business class cabin partitions to create more space inthebusiness class cabin.3 With the partitions moved and the seats converted to Prestige Sleeper configuration, there will be a significant increase in pitch: from 60" at present to 74" (with no changes in aisle width). See Exhibit KE-A attached hereto. This conversion isplanned for Korean's five A330- 200E aircraft, four ofwhichhave been delivered and one ofwhich is scheduled for delivery in early 2013. Korean respectfullyrequests that the Department extend its Determinationtothe seat configuration changes discussed above. The Departmenthas previously approved boththe Prestige Plus and Prestige Sleeper seats. Korean's planned conversion (changing the seat from a 170 degree "almost flat" to 180 degree ''full nat" configuration and adding a full 14 inches of pitch) will only serve to increase passenger c· •mfort and convenience and will ease seat transfers for mobility impaired passengers. Ifyou require any additional informcjon concerningthis request, please do not hesitate to contact us.
Respectfully submitted,
