FAA AD Differences
Note 2: This AD differs from the MCAI
and/or service information as follows:
(1) The maintenance tasks specified in the
first row of the table in ‘‘Part IV. Maintenance
Actions’’ of the MCAI do not specify a
corrective action if an actuator is not
serviceable (i.e., torque test results are not
satisfactory). However, this AD requires
contacting the FAA or installing a serviceable
actuator before further flight if torque test
results are not satisfactory. (Reference
paragraph (f)(4) of this AD.)
(2) Although paragraph 2. of ‘‘Part III.
Training’’ of the MCAI recommends
accomplishing the initial training within 1
year, this AD requires accomplishing the
training before November 30, 2008, in order
to ensure that the actions are completed prior
to the onset of cold weather operations.
(3) The MCAI does not specify which
actuators are applicable to the actions
specified in ‘‘Part C’’ of Bombardier Service

AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for certain
oxygen reserve cylinders. This AD
results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country with which we have a
bilateral agreement to identify and
correct an unsafe condition on an
aviation product. The MCAI describes
the unsafe condition as:
This Airworthiness Directive (AD) is
issued following information concerning the
risk of high-pressure oxygen cylinder tearing
with sudden emptying. These cylinders are
used for missions at high altitudes or to
ensure respiratory air for passengers feeling
sick.
It has been demonstrated that the material
characteristics of the Aluminum Alloy 5283
(AA5283) from which the cylinders are
manufactured deteriorate in the course of
time and may possibly lead these oxygen
cylinders to tear and abruptly vent aboard an
aircraft.
This unsafe condition requires
immediate action due to the risk of
oxygen cylinders exploding on board an
aircraft and creating a fire hazard. This
AD requires actions that are intended to
address this unsafe condition.

Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
follow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct
unsafe conditions on U.S.-certificated
products.
This AD references the MCAI and
related service information that we
considered in forming the engineering
basis to correct the unsafe condition.
The AD contains text copied from the
MCAI and for this reason might not
follow our plain language principles.

Discussion
The European Aviation Safety Agency
(EASA), which is the technical agent for
the member states of the European
community, has issued EASA AD No.
2006–0286R1, dated March 22, 2007, to
correct an unsafe condition for the
specified products.
The MCAI states:
This Airworthiness Directive (AD) is
issued following information concerning the
risk of high-pressure oxygen cylinder tearing
with sudden emptying. These cylinders are
used for missions at high altitudes or to
ensure respiratory air for passengers feeling
sick.
It has been demonstrated that the material
characteristics of the Aluminum Alloy 5283
(AA5283) from which the cylinders are
manufactured deteriorate in the course of
time and may possibly lead these oxygen
cylinders to tear and abruptly vent aboard an
aircraft.
You may obtain further information
by examining the MCAI and the service
information in the AD docket.
Relevant Service Information
Intertechnique has issued Service
Bulletin No. GLD/GLF–35–150, dated
September 20, 2006 and Eurocopter has
issued Alert Service Bulletin Nos.
05.00.54 for the Model AS350B3
helicopters and 05.42 for the Model SA
315B helicopters, both dated August 16,
2006. The actions described in the
MCAI are intended to correct the same
unsafe condition identified in the
service information.
FAA’s Determination and Requirements
of This AD
The Model Airbus 300 series; Pilatus
P–6; Dassault Aviation Mystere-Falcon
20; Falcon 50, Falcon 200, and Falcon
900 airplanes; Eurocopter AS350 and
Eurocopter SA315 helicopters; and
other aircraft may be equipped with
these oxygen reserve cylinders, which
are not approved by the Department of
Transportation (DOT). Without the DOT
approval, these oxygen reserve cylinders
are not eligible for use in aircraft
operating in the United States. Pursuant
to our bilateral agreement with France,
the State of Design, we have been
notified of the unsafe condition
described in the MCAI and service
information. We are issuing this AD
because we evaluated all pertinent
information and determined the unsafe
condition exists and is likely to exist or
develop on aircraft of various type
designs.
Differences Between the AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
PO 00000
Frm 00009
Fmt 4700

general, agree with their substance.
However, we have made the following
changes:
• The MCAI requires removal of the
affected oxygen cylinders at specific
time intervals; however, this AD
requires removal before further flight.
• The MCAI requires certain
procedures to be used for emptying the
cylinders as well as certain action for
cylinders held as spares.
These actions are beyond the scope of
the action needed to correct this unsafe
condition and are not included in this
AD. These differences are highlighted in
the ‘‘Differences Between the FAA AD
and the MCAI’’ section of this AD.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because of the risk of oxygen
cylinders exploding on board an aircraft
and creating a fire hazard. Therefore, we
determined that notice and opportunity
for public comment before issuing this
AD are impracticable and that good
cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and
opportunity for public comment. We
invite you to send any written relevant
data, views, or arguments about this AD.
Send your comments to an address
listed under the ADDRESSES section.
Include ‘‘Docket No. FAA–2007–0374;
Directorate Identifier 2007–SW–02–AD’’
at the beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
this AD. We will consider all comments
received by the closing date and may
amend this AD because of those
comments.
We will post all comments we
receive, without change, to https://
regulations.gov including any personal
information you provide. We will also
post a report summarizing each
substantive verbal contact we receive
about this AD.
Costs of Compliance
We estimate that this AD will affect
about 468 aircraft of U.S. registry. We
also estimate that it will take about 1⁄2
of a work-hour per aircraft to remove the
cylinders. The average labor rate is $80
per work-hour. Based on these figures,
we estimate the cost of this AD on U.S.

§ 39.13
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
section 106, describes the authority of
the FAA Administrator. ‘‘Subtitle VII:
Aviation Programs,’’ describes in more
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in ‘‘Subtitle VII,
Part A, Subpart III, Section 44701:
General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.
Regulatory Findings
We determined that this AD will not
have federalism implications under
Executive Order 13132. This AD will
not have a substantial direct effect on
the States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify this AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
3. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
We prepared an economic evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

the Aluminum Alloy 5283 (AA5283) from which the cylinders are
manufactured deteriorate in the course of time and may possibly lead
these oxygen cylinders to tear and abruptly vent aboard an aircraft.
You may obtain further information by examining the MCAI and the
service information in the AD docket.
Relevant Service Information
Intertechnique has issued Service Bulletin No. GLD/GLF-35-150,
dated September 20, 2006 and Eurocopter has issued Alert Service
Bulletin Nos. 05.00.54 for the Model AS350B3 helicopters and 05.42 for
the Model SA 315B helicopters, both dated August 16, 2006. The actions
described in the MCAI are intended to correct the same unsafe condition
identified in the service information.
FAA's Determination and Requirements of This AD
The Model Airbus 300 series; Pilatus P-6; Dassault Aviation
Mystere-Falcon 20; Falcon 50, Falcon 200, and Falcon 900 airplanes;
Eurocopter AS350 and Eurocopter SA315 helicopters; and other aircraft
may be equipped with these oxygen reserve cylinders, which are not
approved by the Department of Transportation (DOT). Without the DOT
approval, these oxygen reserve cylinders are not eligible for use in
aircraft operating in the United States. Pursuant to our bilateral
agreement with France, the State of Design, we have been notified of
the unsafe condition described in the MCAI and service information. We
are issuing this AD because we evaluated all pertinent information and
determined the unsafe condition exists and is likely to exist or
develop on aircraft of various type designs.
Differences Between the AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. However, we have made the
following changes:
The MCAI requires removal of the affected oxygen cylinders
at specific time intervals; however, this AD requires removal before
further flight.
The MCAI requires certain procedures to be used for
emptying the cylinders as well as certain action for cylinders held as
spares.
These actions are beyond the scope of the action needed to correct
this unsafe condition and are not included in this AD. These
differences are highlighted in the ``Differences Between the FAA AD and
the MCAI'' section of this AD.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because of
the risk of oxygen cylinders exploding on board an aircraft and
creating a fire hazard. Therefore, we determined that notice and
opportunity for public comment before issuing this AD are impracticable
and that good cause exists for making this amendment effective in fewer
than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2007-0374; Directorate
Identifier 2007-SW-02-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to https://
regulations.gov including any personal information you provide. We will
also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD will affect about 468 aircraft of U.S.
registry. We also estimate that it will take about \1/2\ of a work-hour
per aircraft to remove the cylinders. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of this AD on
U.S.
[[Page 1970]]
operators to be $4000, assuming that oxygen cylinders are installed on
100 aircraft.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.
For the reasons discussed above, I certify this AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2007-26-11 Intertechnique Zodiac Aircraft Systems: Amendment 39-
15313. Docket No. FAA-2007-0374; Directorate Identifier 2007-SW-02-
AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective January
28, 2008.
Other Affected ADs
(b) None.
Applicability
(c) This AD applies to Intertechnique (F5341), aluminum alloy
AA5283, oxygen cylinders manufactured by Societe Metallurgique de
Gerzat SAS with GLD series, GLF series, PC2300 or SLF300 part
numbers, installed in any aircraft certificated in any category.
These oxygen reserve cylinders are installed on but not limited to
Model Airbus 300 series; Pilatus P-6; Dassault Aviation Mystere-
Falcon 20, Falcon 50, Falcon 200, and Falcon 900 airplanes; and
Eurocopter AS350 and Eurocopter SA315 helicopters.
Reason
(d) The mandatory continued airworthiness information (MCAI)
states:
This Airworthiness Directive (AD) is issued following
information concerning the risk of high-pressure oxygen cylinder
tearing with sudden emptying. These cylinders are used for missions
at high altitudes or to ensure respiratory air for passengers
feeling sick.
It has been demonstrated that the material characteristics of
the Aluminum Alloy 5283 (AA5283) from which the cylinders are
manufactured deteriorate in the course of time and may possibly lead
these oxygen cylinders to tear and abruptly vent aboard an aircraft.
Actions and Compliance
(e) Unless already done, remove any affected oxygen reserve
cylinder before further flight.
Differences Between the FAA AD and the MCAI
(f) This AD differs from the MCAI as follows:
(1) The MCAI requires removal of the affected oxygen cylinders
at specific time intervals; however, this AD requires removal before
further flight.
(2) The MCAI requires certain procedures to be used for emptying
the cylinders as well as certain action for cylinders held as
spares. These actions are beyond the scope of the action needed to
correct this unsafe condition and are not included in this AD.
