DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 23

[Docket No. CE285, Special Conditions No. 23-225A-SC]

Final Special Conditions: AmSafe Aviation; Inflatable Restraints
Installation; Approved Model List of Normal and Utility Category
Airplanes, and Agricultural Airplanes Certificated in the Normal/
Utility/Restricted Category

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final special conditions; request for comments.

-----------------------------------------------------------------------

SUMMARY: These special conditions are issued for AmSafe Aviation to
amend the list of approved models. These airplanes, as modified by
AmSafe Aviation, will have novel and unusual design features associated
with the lap belt or shoulder harness portion of the safety belt, which
contains an integrated airbag device. The applicable airworthiness
regulations do not contain adequate and appropriate safety standards
for this design feature. 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
airworthiness standards.

DATES: The effective date of these amended special conditions is
October 31, 2008. Comments must be received on or before December 8,
2008.

ADDRESSES: Mail two copies of your comments on these amended special
conditions to: Federal Aviation Administration (FAA), Regional Counsel,
ACE-7, Attention: Rules Docket, Docket No. CE285, 901 Locust, Room 506,
Kansas City, Missouri 64106, or you may deliver two copies to the
Regional Counsel at the above address. Mark your comments: Docket No.
CE285. You may inspect comments in the Rules Docket weekdays, except
Federal holidays, between 7:30 a.m. and 4 p.m.

FOR FURTHER INFORMATION CONTACT: Mr. Bob Stegeman, Federal Aviation
Administration, Small Airplane Directorate, Aircraft Certification
Service, ACE-111, 901 Locust, Kansas City, Missouri, 816-329-4140, fax
816-329-4090, e-mail Robert.Stegeman@faa.gov.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice and
opportunity for prior public comment hereon are impracticable because
these procedures would significantly delay issuance of the approval
design and thus delivery of the affected aircraft. In addition, the
substance of these special conditions has been subject to the public
comment process in several prior instances with no substantive comments
received. The FAA, therefore, finds that good cause exists for making
these amended special conditions effective upon issuance.

Comments Invited

We invite interested persons to participate in the making of these
special conditions by submitting such written data, views, or arguments
as they may desire. Identify the regulatory docket or notice number and
submit the comments in duplicate to the address specified above. All
comments received on or before the closing date for comments will be
considered by the Administrator. The special conditions may be changed
in light of the comments received. All comments received will be
available in the Rules Docket for examination by interested persons,
both before and after the closing date for comments. A report
summarizing each substantive public contact with FAA personnel
concerning this rulemaking will be filed in the docket. Commenters
wishing the FAA to acknowledge receipt of their comments submitted in
response to this notice must include a self-addressed, stamped postcard
on which the following statement is made: ``Comments to CE285.'' The
postcard will be date stamped and returned to the commenter.

Background

On June 18, 2008, AmSafe Aviation, 1043 North 47th Avenue, Phoenix,
AZ 85043, applied to add several more models to an existing
supplemental type certificate. The AML STC allows for the installation
of inflatable restraints in airplane models included herein that were
certificated prior to the dynamic seat rule specified in 14 CFR part
23, Sec. 23.562.
AmSafe Aviation has previously applied for and obtained an Approved
Model List (AML) Supplemental Type Certificate (STC) for the
installation of Inflatable Two-, Three-, Four- or Five-Point Restraint
Safety Belts with an Integrated Airbag Device in airplanes certificated
in the Part 23 Normal/Utility and Restricted-Agricultural categories.
This special condition includes additional normal and utility
category aircraft.
The inflatable restraint system is either a two-, three-, four-, or
five-point safety belt restraint system consisting of a shoulder
harness and a lap belt with an inflatable airbag attached to either the
lap belt or the shoulder harness. The inflatable portion of the
restraint system will rely on sensors to electronically activate the
inflator for deployment. The inflatable restraint system will be made
available on the pilot, co-pilot, and passenger seats of these
airplanes.
If an emergency landing occurs, the airbag will inflate and provide
a protective cushion between the occupant's head and structure within
the airplane. This will reduce the potential for head and torso injury.
The inflatable restraint behaves in a manner that is similar to an
automotive airbag. However, in this case, the airbag is integrated into
the lap or shoulder belt. While airbags and inflatable restraints are
standard in the automotive industry, the use of an inflatable restraint
system is novel for aircraft operations.
The FAA has determined that this project will be accomplished on
the basis of not lowering the current level of safety of the airplanes'
original certification basis. The FAA has two primary safety concerns
with the installation of airbags or inflatable restraints:
That they perform properly under foreseeable operating
conditions; and
That they do not perform in a manner or at such times as
to impede the pilot's ability to maintain control of the airplane or
constitute a hazard to the airplane or occupants.
The latter point has the potential to be the more rigorous of the
requirements. An unexpected deployment while conducting the takeoff or
landing phases of flight may result in an unsafe condition. The
unexpected deployment may either startle the pilot, or it may generate
a force sufficient to cause a sudden movement of the control yoke.
Either action could result in a loss of control of the airplane, the
consequences of which are magnified due to the low operating altitudes
during these phases of flight. This consideration is of special concern
for aircraft designated for agricultural use because these aircraft
spend a majority of their flight time at low altitudes. The FAA has
considered this when establishing these amended special conditions.
The inflatable restraint system relies on sensors to electronically
activate the inflator for deployment. These sensors could be
susceptible to inadvertent activation, causing deployment in a
potentially unsafe manner. The consequences of an inadvertent
deployment must be considered in establishing the reliability of the
system. AmSafe Aviation must show that the effects of an inadvertent
deployment in flight are not a hazard to the airplane or that an
inadvertent deployment is extremely improbable.
In addition, general aviation and agricultural aircraft are
susceptible to a large amount of cumulative wear and tear on a
restraint system. It is likely that the potential for inadvertent
deployment increases as a result of this cumulative damage. Therefore,
the impact of wear and tear on inadvertent deployment must be
considered. Due to the effects of this cumulative damage, a life limit
must be established for the appropriate system components in the
restraint system design.
There are additional factors to be considered to minimize the
chances of inadvertent deployment. General aviation airplanes are
exposed to a unique operating environment, since the same airplane may
be used by both experienced and student pilots. The effect of this
environment on inadvertent deployment must be understood. Therefore,
qualification testing of the firing hardware/software must consider the
following:
The airplane vibration levels appropriate for general
aviation and agricultural airplanes; and
The inertial loads that result from typical flight/ground
maneuvers, gusts, hard landings and flight maneuvering unique to both
general aviation and agricultural aircraft operations.
Any tendency for the firing mechanism to activate as a result of
these loads or acceleration levels is unacceptable.
Other influences on inadvertent deployment include high intensity
electromagnetic fields (HIRF) and lightning. Since the sensors that
trigger deployment are electronic, they must be protected from the
effects of these threats. To comply with HIRF and lightning
requirements, the AmSafe Aviation inflatable restraint system is
considered a critical system, since its inadvertent deployment could
have a hazardous effect on the airplane.
Given the level of safety of the retrofitted airplane occupant
restraints,

[[Page 66165]]

the inflatable restraint system must show that it will offer an
equivalent level of protection in the event of an emergency landing. If
a deployment occurs, the restraint must still be at least as strong as
a Technical Standard Order approved belt and shoulder harnesses. There
is no requirement for the inflatable portion of the restraint to offer
protection during multiple impacts.
The inflatable restraint system must deploy and provide protection
for each occupant during crash conditions as specified in the original
certification basis. Therefore, the test emergency landing loads
identified in the original certification basis of the airplane must be
used to satisfy this requirement. It must be shown that the inflatable
restraint will deploy and provide protection under crash conditions as
specified in the original certification basis. Compliance will be
demonstrated using the test condition specified in the original
certification basis. It must be shown that the crash sensor will
trigger when exposed to a rapidly applied deceleration, like an actual
crash event. Therefore, the test crash pulses identified in Sec.
23.562 must be used to satisfy this requirement, although the peak
``G'' may be reduced to a level meeting the original certification
requirements of the aircraft. Testing to these pulses will demonstrate
that the crash sensor will trigger when exposed to a rapidly applied
deceleration, like an actual crash event.
It is possible a wide range of occupants will use the inflatable
restraint. Thus, the protection offered by this restraint should be
effective for occupants that range from the fifth percentile female to
the ninety-fifth percentile male.
In support of this operational capability, there must be a means to
verify the integrity of this system before each flight. As an option,
AmSafe Aviation can establish inspection intervals where they have
demonstrated the system to be reliable between these intervals.
An inflatable restraint may be ``armed'' even though no occupant is
using the seat. While there will be means to verify the integrity of
the system before flight, it is also prudent to require that unoccupied
seats with active restraints not constitute a hazard to any occupant.
This will protect any individual performing maintenance inside the
cockpit while the aircraft is on the ground. The restraint must also
provide suitable visual warnings that would alert rescue personnel to
the presence of an inflatable restraint system.
In addition, the design must prevent the inflatable seatbelt from
being incorrectly buckled and/or installed such that the airbag would
not properly deploy. As an alternative, AmSafe Aviation may show that
such deployment is not hazardous to the occupant and will still provide
the required protection.
The cabins of the various model airplanes identified in these
special conditions are confined areas, and the FAA is concerned that
noxious gases may accumulate if an airbag deploys. When deployment does
occur, either by design or inadvertently, there must not be a release
of hazardous quantities of gas or particulate matter into the cockpit.
An inflatable restraint should not increase the risk already
associated with fire. Therefore, the inflatable restraint should be
protected from the effects of fire, so that an additional hazard is not
created by, for example, a rupture of the inflator.
Finally, the airbag is likely to have a large volume displacement,
and it may impede the egress of an occupant. Since the bag deflates to
absorb energy, it is likely that the inflatable restraint would be
deflated at the time an occupant would attempt egress. However, it is
appropriate to specify a time interval after which the inflatable
restraint may not impede rapid egress. Ten seconds has been chosen as
reasonable time. This time limit will offer a level of protection
throughout the impact event.
Special conditions for the installation of AAIR systems on other
certificated airplanes have been issued and no substantive public
comments were received. Since the same special conditions were issued
multiple times for different model airplanes with no substantive public
comments, the FAA began issuing direct final special conditions with an
invitation for public comment. This was done to eliminate the waiting
period for public comments and to allow AmSafe Aviation to proceed with
the project.
These previous special conditions were typically issued for a
single model airplane or for variants of a model from a single airplane
manufacturer, and required dynamic testing of each AAIR system
installation for showing compliance. Since AmSafe Aviation has
previously demonstrated by dynamic testing, and has the supporting
data, that the Electronics Module Assembly (EMA) and inflator assembly
will function as intended in a simulated dynamic emergency landing, it
is not necessary to repeat the test for each airplane model shown in
these amended special conditions.

Type Certification Basis

Under the provisions of 14 CFR part 21, Sec. 21.101, AmSafe
Aviation must show that affected airplane models, as changed, continue
to meet the applicable provisions of the regulations incorporated by
reference in the Type Certificate Numbers listed below or the
applicable regulations in effect on the date of application for the
change. The regulations incorporated by reference in the type
certificate data sheet are commonly referred to as the original ``type
certification basis'' and can be found in the Type Certificate Data
Sheets for the numbers listed below. The following models are covered
by this amended special condition:

Aircraft identified with a 1 have special conditions for AmSafe Aviation Inflatable Restraints published under Special Conditions 23-182-SC.
Piper PA-18A, PA-18A ``135'' and PA-18A ``150'' (identified with a 2) are type certificated in Normal/Utility Category on TCDS 1A2 and in Restricted
Category on TCDS AR-7. The same aircraft may be operated under either TCDS in accordance with the restrictions listed on TCDS AR-7.
Ximango (identified with a 3) is certificated in the Utility Category.

For all the models listed above, the certification basis also
includes all exemptions, if any; equivalent level of safety findings,
if any; and the other special conditions.
If the Administrator finds that the applicable airworthiness
regulations (i.e., part 23 as amended) do not contain adequate or
appropriate safety standards for the AmSafe Aviation, inflatable
restraint as installed on these models because of a novel or unusual
design feature, special conditions are prescribed under the provisions
of Sec. 21.16.
Special conditions, as appropriate, as defined in Sec. 11.19, are
issued in accordance with Sec. 11.38, and become part of the type
certification basis in accordance with Sec. 21.101.
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,
the special conditions would also apply to that model under the
provisions of Sec. 21.101.

Novel or Unusual Design Features

The various airplane models will incorporate the following novel or
unusual design feature:
The AmSafe Aviation Inflatable Two-, Three-, Four-, or Five-Point
Restraint Safety Belt with an Integrated Airbag Device.
The purpose of the airbag is to reduce the potential for injury in
the event of an accident. In a severe impact, an airbag will deploy
from the restraint, in a manner similar to an automotive airbag. The
airbag will deploy between the head of the occupant and airplane
interior structure. This will, therefore, provide some protection to
the head of the occupant. The restraint will rely on sensors to
electronically activate the inflator for deployment.
The Code of Federal Regulations state performance criteria for
seats and restraints in an objective manner. However, none of these
criteria are adequate to address the specific issues raised concerning
inflatable restraints. Therefore, the FAA has determined that, in
addition to the requirements of part 21 and part 23, special conditions
are needed to address the installation of this inflatable restraint.
Accordingly, these amended special conditions are adopted for the
various airplane models equipped with the AmSafe Aviation, two-, three-
, four, or five-point inflatable restraint. Other conditions may be
developed, as needed, based on further FAA review and discussions with
the manufacturer and civil aviation authorities.

Applicability

As discussed above, these amended special conditions are applicable
to the Approved Model List (AML) above. Should AmSafe Aviation apply at
a later date for a supplemental type certificate to modify any other
model included on the type certificates listed above to incorporate the
same novel or unusual

[[Page 66171]]

design feature, the special conditions would apply to that model as
well.

Conclusion

This action affects only certain novel or unusual design features
on the previously identified airplane models. It is not a rule of
general applicability, and it affects only the applicant who applied to
the FAA for approval of these features on the airplane.
Under standard practice, the effective date of final special
conditions would be 30 days after the date of publication in the
Federal Register; however, as the certification date for these airplane
models, as modified by AmSafe Aviation, is imminent, the FAA finds that
good cause exists to make these amended special conditions effective
upon issuance.

The authority citation for these amended special conditions is as

Authority: 49 U.S.C. 106(g), 40113 and 44701; 14 CFR 21.16 and
21.101; and 14 CFR 11.38 and 11.19.

The Amended Special Conditions

The FAA has determined that this project will be accomplished on
the basis of not lowering the current level of safety of the occupant
restraint system for the airplane models listed in these special
conditions. Accordingly, the FAA is issuing the following amended
special conditions as part of the type certification basis for these
models, as modified by AmSafe, Aviation.
Inflatable Two-, Three-, Four-, or Five-Point Restraint Safety Belt
with an Integrated Airbag Device Installed in an Airplane Model.
1a. It must be shown that the inflatable restraint will provide
restraint protection under the emergency landing conditions specified
in the original certification basis of the airplane. Compliance will be
demonstrated using the static test conditions specified in the original
certification basis for each airplane.
1b. It must be shown that the crash sensor will trigger when
exposed to a rapidly applied deceleration, like an actual emergency
landing event. Therefore, compliance may be demonstrated using the
deceleration pulse specified in Sec. 23.562, which may be modified as
follows:

I. The peak longitudinal deceleration may be reduced; however,
the onset rate of the deceleration must be equal to or greater than
the emergency landing pulse identified in Sec. 23.562.
II. The peak longitudinal deceleration must be above the
deployment threshold of the sensor, and equal or greater than the
forward static design longitudinal load factor required by the
original certification basis of the airplane.

2. The inflatable restraint must provide adequate protection for
each occupant. In addition, unoccupied seats that have an active
restraint must not constitute a hazard to any occupant.
3. The design must prevent the inflatable restraint from being
incorrectly buckled and/or incorrectly installed such that the airbag
would not properly deploy. Alternatively, it must be shown that such
deployment is not hazardous to the occupant and will provide the
required protection.
4. It must be shown that the inflatable restraint system is not
susceptible to inadvertent deployment as a result of wear and tear or
the inertial loads resulting from in-flight or ground maneuvers
(including gusts and hard landings) that are likely to be experienced
in service.
5. It must be extremely improbable for an inadvertent deployment of
the restraint system to occur, or an inadvertent deployment must not
impede the pilot's ability to maintain control of the airplane or cause
an unsafe condition (or hazard to the airplane). In addition, a
deployed inflatable restraint must be at least as strong as a Technical
Standard Order (C22g or C114) restraint.
6. It must be shown that deployment of the inflatable restraint
system is not hazardous to the occupant or will not result in injuries
that could impede rapid egress. This assessment should include
occupants whose restraints are loosely fastened.
7. It must be shown that an inadvertent deployment that could cause
injury to a sitting person is improbable. In addition, the restraint
must also provide suitable visual warnings that would alert rescue
personnel to the presence of an inflatable restraint system.
8. It must be shown that the inflatable restraint will not impede
rapid egress of the occupants 10 seconds after its deployment.
9. For the purposes of complying with HIRF and lightning
requirements, the inflatable restraint system is considered a critical
system since its deployment could have a hazardous effect on the
airplane.
10. It must be shown that the inflatable restraints will not
release hazardous quantities of gas or particulate matter into the
cabin.
11. The inflatable restraint system installation must be protected
from the effects of fire such that no hazard to occupants will result.
12. There must be a means to verify the integrity of the inflatable
restraint activation system before each flight or it must be
demonstrated to reliably operate between inspection intervals.
13. A life limit must be established for appropriate system
components.
14. Qualification testing of the internal firing mechanism must be
performed at vibration levels appropriate for a general aviation
airplane.
