SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and
opportunity for prior public comment on, these special conditions is
impracticable because these procedures would significantly delay
issuance of the design approval and thus delivery of the affected
airplane.
    In addition, the substance of these special conditions has been
previously subject to the public comment process with no substantive
comments received. The FAA therefore finds it unnecessary to delay the
effective date and finds that good cause exists for making these
special conditions effective upon publication in the Federal Register.

Comments Invited

    We invite interested people to take part in this rulemaking by
sending written comments, data, or views. The most helpful comments
reference a specific portion of the special conditions, explain the
reason for any recommended change, and include supporting data.
    We will consider all comments we receive by the closing date for
comments. We may change these special conditions based on the comments
we receive.

Background

    On September 7, 2016, AMAC applied for a supplemental type
certificate (STC) for the installation of a supplemental therapeutic
oxygen system, for medical use, in a Boeing Model 737-700 airplane
configured by a separate STC with a business-cabin interior. This
Boeing Model 737-700 airplane, as modified by AMAC, is a narrow-body,
business-cabin interior, twin jet-engine powered airplane with seating
for 15 passengers, 1 cabin crewmember, and four flightcrew members. The
maximum takeoff weight is 171,000 pounds.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, AMAC must show that the Boeing Model 737-700 airplane, as
changed, continues to meet the applicable provisions of the regulations
listed in Type Certificate No. A16WE or the applicable regulations in
effect on the date of application for the change, except for earlier
amendments as agreed upon by the FAA.
    If the Administrator finds that the applicable airworthiness
regulations (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the Boeing Model 737-700 airplane
because of a novel or unusual design feature, special conditions are
prescribed under the provisions of Sec.  21.16.

    Special conditions are initially applicable to the model for which
they are issued. Should the applicant apply for a supplemental type
certificate to modify any other model included on the same type
certificate to incorporate the same novel or unusual design feature,
these special conditions would also apply to the other model under
Sec.  21.101.
    In addition to the applicable airworthiness regulations and special
conditions, the Boeing Model 737-700 airplane must comply with the
fuel-vent and exhaust-emission requirements of 14 CFR part 34 and the
noise-certification requirements of 14 CFR part 36.
    The FAA issues special conditions, as defined in 14 CFR 11.19, in
accordance with Sec.  11.38, and they become part of the type
certification basis under Sec.  21.101.

Novel or Unusual Design Features

    The Boeing Model 737-700 airplane, as changed, will incorporate the
following novel or unusual design features:
    The installation of a supplemental therapeutic oxygen system, for
medical use, in a private, not-for-hire, not-for-common-carriage
airplane.

Discussion

    AMAC has applied to modify a private business jet, a Boeing 737-700
airplane, to include an oxygen supply for a dedicated medical-oxygen
system. The gaseous passenger-oxygen system will be modified to include
additional supply cylinders and several therapeutic oxygen outlets
located throughout the airplane cabin. Each therapeutic outlet will
provide a constant flow of oxygen at either 2 or 4 liters per minute.
    The flightcrew controls the flow of therapeutic oxygen at all times
during flight. Therapeutic oxygen systems have been previously
certified and were generally considered an extension of the passenger-
oxygen system for the purpose of defining the applicable regulations.
As a result, the applicable regulations included those that applied to
oxygen systems in general, or supplemental oxygen systems.
    Section 25.1445 includes standards for oxygen-distribution systems
when oxygen is supplied to crew and passengers. If a common source of
supply is used, Sec.  25.1445(a)(2) requires a means to separately
reserve the minimum supply required for the flightcrew. This
requirement was originally added to Civil Air Regulation (CAR) 4b.831
at amendment 4b-13, effective September 21, 1949, and was included in
Sec.  25.1445 when the regulations were codified.
    The regulation is intended to protect the flightcrew by ensuring
that an adequate supply of oxygen is available to complete a descent
and land following a loss of cabin pressure. When the regulation was
written, the only passenger-oxygen system designs were supplemental-
oxygen systems intended to protect passengers from hypoxia in the event
of cabin decompression. Present designs of passenger-oxygen systems do
not include design features that allow the crew to offer oxygen to
passengers during flight.
    Furthermore, the potential hazard that can exist when the oxygen
content of an enclosed area becomes too high because of system leaks,
malfunction, or damage from external sources, make it necessary to
ensure that adequate safety standards are applied to the design and
installation of the oxygen system. These potential hazards also
necessitate development and application of appropriate additional
design and installation standards.
    These special conditions contain the additional safety standards
that the Administrator considers necessary to establish a level of
safety equivalent to that established by the existing airworthiness
standards.

Applicability

    As discussed above, these special conditions are applicable to the
Boeing Model 737-700 airplane. Should AMAC apply at a later date for a
supplemental type certificate to modify any other model included on
Type Certificate no. A16WE to incorporate the same novel or unusual
design feature, these special conditions would apply to that model as
well.

Conclusion

    This action affects only certain novel or unusual design features
on one model of airplane. It is not a rule of general applicability and
affects only the applicant who applied to the FAA for approval of this
feature on the airplane.
    The substance of these special conditions has been subject to the
notice and comment period in several prior instances and has been
derived without substantive change from those previously issued. It is
unlikely that prior public comment would result in a significant change
from the substance contained herein. Therefore, because a delay would
significantly affect the certification of the airplane, which is
imminent, the FAA has determined that prior public notice and comment
are unnecessary and impracticable, and good cause exists for adopting
these special conditions upon publication in the Federal Register.
    The FAA is requesting comments to allow interested persons to
submit views that may not have been submitted in response to the prior
opportunities for comment described above.

List of Subjects in 14 CFR Part 25

    Aircraft, Aviation safety, Reporting and recordkeeping
requirements.

    The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704.

The Special Conditions

    Accordingly, pursuant to the authority delegated to me by the
Administrator, the following special conditions are issued as part of
the type certification basis for Boeing Model 737-700 airplanes as
modified by AMAC Aerospace Switzerland AG.
    The distribution system for the therapeutic-oxygen system must be
designed and installed to meet requirements similar to Sec.  25.1445(a)
as follows:
    When oxygen is supplied to passengers for both supplemental and
therapeutic purposes, the distribution system must be designed for
either--
    1. A source of supplemental supply for protection from hypoxia
following a loss of cabin pressure, and a separate source for
therapeutic purposes, or
    2. A common source of supply, with means to separately reserve the
minimum supply required by the passengers for supplemental use
following a loss of cabin pressure.
