<h2 style="margin-bottom: 13px;">Do you want to transform your ERJ 135, 140, or 145 into a luxury semi-private aircraft?</h2>
Semi-private aircraft are usually regional-sized jets with fewer seats, allowing for upgraded seats, more legroom, and personal space. ERJ 135, 140, and 145 aircraft with traditionally configured seating can be easily converted to resemble a first-class or private jet interior. However, semi-private conversions remain a niche market, with only a few MROs providing those services.&nbsp;
As one of those MROs, we at C&amp;L Aviation Group often get asked about the available ERJ semi-private upgrade possibilities. While other MROs may offer different solutions, we created this article to help you understand the services and options for each of our ERJ interior refurbishment packages, estimated costs, and expected downtime.
<h2>ERJ 135, 140 &amp; 145 Semi-Private Aircraft Packages&nbsp;</h2>
C&amp;L Aviation Group has created the following four packages for operators interested in entering the semi-private travel market:
<ol>
<li>Regular Commercial Layout</li>
<li>30-Seat Layout</li>
<li>Space Jet</li>
<li>VIP Jet</li>
</ol>
Each package is fully customizable with add-on options to make your ERJ 135, 140, or 145 aircraft reflect your unique branding.&nbsp;

Our Regular Commercial Layout package provides ERJ 135, 140, and 145 aircraft with an updated interior while maintaining the original seating configuration. Although this is not a “semi-private” option, it serves as a good place to start in this article as a baseline option. This refurbishment-only option includes the following services:&nbsp;
<ul>
<li>Upholster aircraft cabin seats in new-style leather seat coverings with re-woven seat belts, including flight attendant seats</li>

</ul>
Prices start at $715,000

The Space Jet package provides passengers with ample personal space by reducing the number of seats and replacing some seats along the aisle with tables. The aisle remains offset (same as in a 2:1 seat configuration).
<ul>
<li>20 seats in the ERJ 135</li>
<li>25 or 30 seats in the ERJ 140</li>
<li>30 seats in the ERJ 145&nbsp;</li>
</ul>
This package includes the services and upgrades available for the previous semi-private packages.
Prices start at $850,000
Estimated turnaround time: 120 days

The VIP Jet package is the highest level of conversion. This package offers reduced seat density, providing the most personal space for passengers. The number of seats per aircraft type is as follows:
<ul>
<li>16 seats in the ERJ 135</li>
<li>18 seats in the ERJ 140</li>
<li>22 seats in the ERJ 145</li>
</ul>

Estimated turnaround time: 120 days

<h2 style="margin-bottom: 13px;">C&amp;L’s Semi-Private Supplemental Type Certificates</h2>
To complete the VIP Jet seating conversion, C&amp;L holds three FAA and EASA approved supplemental type certificates (STCs) for ERJ 135, 140 &amp; 145 semi-private conversions.
<h3>Flat Floor Modification STC</h3>
Under the STC (<a href="https://drs.faa.gov/browse/excelExternalWindow/DRSDOCID154500301020230725135813.0001">ST04527CH</a>), the cabin floor is leveled and business-class seats are installed. Flat floor modifications change the seat configuration to include a center aisle. The existing aisle in the ERJ is off-center due to the 2:1 regional seating configuration.
Flat floor modifications allow for 1:1 business class seating with an industry-leading 23.5 inches wide seating area, adjustable lumbar, and recline functions with a spacious 40-48 inches seat pitch (depending on the aircraft type), compared to the typical commercial seating pitch of 31 inches. A larger seat pitch provides passengers ample legroom and space to recline comfortably.
Our STC also includes a wider, safer, and more comfortable 20-inch center aisle that exceeds federal regulation requirements.&nbsp;&nbsp;
<h3>Interior STC</h3>
A prerequisite for the Flat Floor Modification STC is the Interior STC (<a href="https://drs.faa.gov/browse/excelExternalWindow/DRSDOCID190564775620230725135556.0001">ST04177NY</a>). This STC includes the removal of overhead bins, the installation of ceiling and valance panels, and the installation of continuous-run LED lights.
This STC also allows for the optional installation of USB dual port Type A and Type C-PD, 110-volt AC power, and a coat wardrobe.

<h3>Floor Path Lighting STC</h3>
Also a prerequisite for the Flat Floor Modification STC, this STC replaces OEM floor path (a.k.a. Emergency) lighting with photoluminescence floor path lighting, thus improving reliability. (Photoluminescence floor path lighting does not require power to be visible during an emergency.)
