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 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 FivePoint 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 § 23.562, which may
be modified as follows:
I. The peak longitudinal deceleration may
be reduced; however, the onset rate of the
VerDate Aug<31>2005

Jkt 217001
deceleration must be equal to or greater than
the emergency landing pulse identified in
§ 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.

SUMMARY: The Mine Safety and Health
Administration (MSHA) is amending
and clarifying its existing health
standards for asbestos exposure. The
amendments make no substantive
change to the existing standards,
MSHA’s enforcement of the standards,
or the protection afforded miners under
the standards.
DATES: This technical amendment is
effective November 7, 2008.

MSHA
published a final rule amending its
health standards for asbestos exposure
at metal and nonmetal mines, surface
coal mines, and surface areas of
underground coal mines on February
29, 2008 (73 FR 11284). The rule
became effective on April 29, 2008. To
assure that the mining community fully
understands MSHA’s intent with
respect to certain provisions of the
existing standards, the Agency is issuing
this technical amendment. This
technical amendment clarifies MSHA’s
definition of asbestos and analytical
methods the Agency uses to enforce the
existing asbestos exposure limit. As
stated above, these clarifications do not
change any substantive requirements
and reflect MSHA’s intent as explained
in the preamble to the final rule issued
on February 29, 2008.
