Now would you like to share the desired Floor Plan and I will ask Jet Aviation to look at it. V-BR Alireza From: jeffrey E.

In reviewing the current and the desired floorplans I realized the layout for the latter hardly retains any seats, divans, furnishings, bulkheads, side-ledges or monuments in their current cabin location. This kind of radical floorplan change would require quite large non-reoccurring engineering (NRE) and certification (STC) effort. The upper and lower supporting structure, potable, gray and waste water plumbing, electrical (IFE/CMS/Cabin Lighting, etc), periphery (i.e. headliners, valances and domes) system, in the current cabin layout would have to be demoded as to allow the new cabin layout. Not being the completion center holding the original interior STC approved engineering data package we would have to create the engineering data required to support the certification process (STC) for the new configuration. The FAA certification level is greater today than it was in 1999, when the original interior was initially certified (STC) In order to salvage and reuse the existing seats, divans, furnishings, bulkheads, side-ledges or monuments the engineering for the installation of these cabin elements would have to be validated. There is the risk that many of the cabin elements certified in the 1999 STC could not be certified in today's regulatory environment. In essence the NRE, labor and material costs and the down-time time involved for the desired floorplan would be even greater than starting with a green aircraft without an interior already in place (8.12 months down-time and $25.0 M. to $30.0 M pri
