What it approves
A new upper deck aft bulkhead partition replaces the existing aft bulkhead partition. This new partition creates additional floor space that allows the upper deck seats to be relocated, thus providing increased bulkhead space for the first row of seats. The new partition consists of five (5) separate panels which are mounted at floor level on existing seat tracks with standard fittings. The upper portion of the partition is attached using existing structure on the frames and tie rods running to the top of the bulkhead. This modification was accomplished in accordance with United Air Lines DAS-1-WE Approved Master Drawing List No. 00016, dated March 5, 1996, or later FAA approved revisions.
