The issue with “Executive Interiors”…
 CS-25 / FAR 25 are not adequate for Business Jets / Corporate Jets / VIP interiors
Rules written for traditional cabin arrangements…
… are not adapted to design non-traditional interiors

The issue with “Executive Interiors”…
 CS-25 / FAR 25 are not adequate for Business Jets / Corporate Jets / VIP interiors
 The certification of “Executive” or “VIP” interiors requires compliance
demonstration against the applicable airworthiness code:
 In EASA: JAR / CS-25
 In FAA:
FAR 25
 This code being partially inadequate, applicants to TC or STC shall comply with
additional technical requirements (Special Conditions), or show that the proposed
interiors provide an equivalent level of safety for the passengers.
 These discussions are recorded during the certification process in documents that
are generally only exchanged between the applicants and the Authorities:
 In EASA: Certification Review Items (CRI)
 In FAA:
Issue Papers (IP)
 Typical Cabin Safety subjects:
 Interior doors
 Isolated compartments
 Emergency exit access
 Emergency exit deactivation…
 A large administrative effort for both Applicants
and Authorities is necessary for each cabin
interior to document all the recurrent
certification issues with CS-25 / FAR 25

The issue with “Executive Interiors”…
 FAA / EASA Approach
 FAA approach
 Strong request by US Industries for common / adapted airworthiness code
 FAA has issued in 2009
SFAR 109 “Special Requirements for Private Use Transport Category Airplanes”
 …but few applications were made against this SFAR because :
o Limited to Private Use only A/C
o Limited to 60 PAX max
 EASA approach
 Strong request by EU Industries for common / adapted airworthiness code
 Lack of EASA resources to include such work in Rulemaking Program
 … but
EASA has accepted to let EU Industries bear the rulemaking effort on an
“exceptional” and “experimental” basis
 Launch of Stakeholder-led Rulemaking Group
on “Executive Interiors”

Preparation of the Future Requirements
 Terms of Reference (ToR)
 Objective set by EASA:
 The overall objectives are the reduction of recurrent CRIs and the mitigation of the diverging
interpretation of safety requirements on interior designs for aeroplanes with executive interiors. This
is to reduce administrative costs and to ensure a common understanding of measures with an
acceptable level of safety similar to current CS-25 requirements when applied to commercial airliners
and to avoid time-consuming activities on repetitive certification issues.
 More specifically, the NPA shall establish Executive Interior design specifications that will amend
and/or complement CS-25 by introducing new provisions and associated AMC/GM for executive
interiors, taking into account the compensating factors offered by such interiors and their
utilisation.

Proposed Future Certification Requirements (Draft NPA)
Approach of the Working Group
 Summary: Non-Commercial and “Low Occupancy” aeroplanes for commercial operations
 The drafted rule therefore proposes to distinguish the products as follows:
Eligibility to
CS-25 Appendix X ?
YES
Is A/C limited to
Non-Commercial and
≤ 150 PAX per deck
Operations ?
NO
Is A/C
Low Occupancy ?
(maximum 19PAX or
≤1/3rd of max TC - Total & per zone
and ≤ 100 PAX per deck)
YES
NO
Non-commercially operated
Requirements / Alleviations
of CS-25 Appendix X
Group 1
« Private »
Low Occupancy
Requirements / Alleviations
of CS-25 Appendix X
General CS-25
Requirements
Group 2
« Low Occupancy »
Group 3
« Airline-like »
2a (≤19)
JMB
Group 2a corresponds to existing
“natural 19” A/C (limitation as per TCDS)
2b (>19)
Group 2b addresses larger airplanes
not limited to 19PAX for public operations
