15,000 hours TIS.
Example 2: S/N yyy was originally a Group
3 airplane; later it was modified with a
PT6A–34, 750 horsepower, turbine engine
when the wing front lower spar caps had
5,300 hours TIS on them. The wing front
lower spar caps now have 7,700 hours TIS.
Usage Factor = 5,300 hours/28,800 + (7,700
¥ 5,300)/6,200 = 0.571
Equivalent Group 1 hours = 6,200 × 0.571 =
3,540 hours.
The wing front lower spar caps will need
to be replaced at 6,200 equivalent Group 1
total hours TIS, which is within the next
2,660 hours TIS (6,200 ¥ 3,540 = 2,660).

ACTION: Final rule; request for
comments.
SUMMARY: The FAA is revising an
existing airworthiness directive (AD),
which applies to certain AVOX Systems
and B/E Aerospace oxygen cylinder
assemblies, as installed on various
transport airplanes. That AD currently
requires removing certain oxygen
cylinder assemblies from the airplane.
This AD removes certain oxygen
cylinder part numbers from the
applicability. This AD was prompted by
the reported rupture of a high-pressure
gaseous oxygen cylinder, which had
insufficient strength characteristics due
to improper heat treatment. We are
issuing this AD to prevent an oxygen
cylinder from rupturing, which,
depending on the location, could result
in structural damage and rapid
decompression of the airplane, damage
to adjacent essential flight equipment,
deprivation of the necessary oxygen
supply for the flightcrew, and injury to

Discussion
On November 25, 2009, we issued AD
2009–21–10, amendment 39–16049 (74
FR 63063, December 2, 2009). That AD
applies to certain AVOX Systems and B/
E Aerospace oxygen cylinder
assemblies, as installed on various
transport airplanes. That AD requires
removing certain oxygen cylinder
assemblies from the airplane. That AD
was prompted by the reported rupture
of a high-pressure gaseous oxygen
cylinder, which had insufficient
strength characteristics due to improper
heat treatment. The actions specified in
that AD are intended to prevent an
oxygen cylinder from rupturing, which,
depending on the location, could result
in structural damage and rapid

decompression of the airplane, damage
to adjacent essential flight equipment,
deprivation of the necessary oxygen
supply for the flightcrew, and injury to
cabin occupants or maintenance or
other support personnel.
Actions Since AD Was Issued
Since we issued AD 2009–21–10, we
have been notified that its applicability
(in paragraph (c)) erroneously includes
oxygen cylinder assemblies having part
numbers B43570–3 and B43570–5.
Those oxygen cylinder assemblies are
manufactured from composite material,
instead of steel, and the erroneous part
numbers do not correspond to any serial
numbers listed in the AD. Composite
oxygen tanks are not subject to the
identified unsafe condition. These part
numbers have been removed from Table
1 of this AD.
We have also been notified that serial
numbers K617383 through K617423
inclusive and K757064 through
K757066 inclusive have been
withdrawn from service. These serial
numbers have been removed from Table
3 of this AD.
FAA’s Determination and Requirements
of This AD
Certain affected airplanes have been
approved by the aviation authorities of
other countries, and are approved for
operation in the United States.
The unsafe condition described
previously is likely to exist or develop
in other products of these same type
designs. For this reason, we are issuing
this AD to revise AD 2009–21–10. This
new AD retains the requirements of the
existing AD, but removes part numbers
B43570–3 and B43570–5 from the
applicability of this AD, and removes
certain serial numbers from Table 3 of
this AD.
Additional Change to AD
We have revised this AD to identify
the legal name of certain manufacturers
as published in the most recent type
certificate data sheet for the affected
airplane models.
FAA’s Justification and Determination
of the Effective Date
This AD addresses the consequences
of the potential rupture of certain
oxygen cylinder assemblies. Because of
our requirement to promote safe flight of
civil aircraft and thus the critical need
to ensure the proper functioning of the
oxygen cylinders and the short
compliance time involved with this
action, this AD must be issued
immediately.
Because an unsafe condition exists
that requires the immediate adoption of

20JAR1
3142
Federal Register / Vol. 75, No. 12 / Wednesday, January 20, 2010 / Rules and Regulations
this AD, we find that notice and
opportunity for prior public comment
hereon are impracticable and that good
cause exists for making this amendment
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not provide you with notice and
an opportunity to provide your
comments before it becomes effective.
However, we invite you to send any
written data, views, or arguments about
this AD. Send your comments to an
address listed under the ADDRESSES
section. Include ‘‘Docket No. FAA–
2010–0029; Directorate Identifier 2009–
NM–262–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://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this AD.
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

Aerospace: Amendment 39–16179.
Docket No. FAA–2010–0029; Directorate
Identifier 2009–NM–262–AD.
that is likely to exist or develop on
products identified in this rulemaking
action.
Regulatory Findings
We have 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 that the regulation:
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 a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.
Effective Date
(a) This airworthiness directive (AD) is
effective February 4, 2010.
Affected ADs
(b) This AD revises AD 2009–21–10,
Amendment 39–16049.
Applicability
(c) This AD applies to the oxygen cylinder
assemblies, approved under United States
Department of Transportation Regulations for
Type 3HT cylinders, identified in Table 1 of
this AD. These oxygen cylinder assemblies
may be installed on various transport
airplanes, certificated in any category,
identified in but not limited to the airplanes
included in Table 2 of this AD.

SUPPLEMENTARY INFORMATION:
Discussion
On November 25, 2009, we issued AD 2009-21-10, amendment 39-16049
(74 FR 63063, December 2, 2009). That AD applies to certain AVOX
Systems and B/E Aerospace oxygen cylinder assemblies, as installed on

immediately.
Because an unsafe condition exists that requires the immediate
adoption of
[[Page 3142]]
this AD, we find that notice and opportunity for prior public comment
hereon are impracticable and that good cause exists for making this
amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
``Docket No. FAA-2010-0029; Directorate Identifier 2009-NM-262-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://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
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 have 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 that the regulation:
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 a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Subject
(d) Air Transport Association (ATA) of America Code 35: Oxygen.
Unsafe Condition
(e) This AD was prompted by the reported rupture of a high-
pressure gaseous oxygen cylinder, which had insufficient strength
characteristics due to improper heat treatment. The Federal Aviation
Administration is issuing this AD to prevent an oxygen cylinder from
rupturing, which, depending on the location, could result in
structural damage and rapid decompression of the airplane, damage to
adjacent essential flight equipment, deprivation of the necessary
oxygen supply for the flightcrew, and injury to cabin occupants or
maintenance or other support personnel.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Restatement of Requirements of AD 2009-21-10, With Revised Serial
Numbers
Inspection
(g) Within 90 days after December 17, 2009 (the effective date
of AD 2009-21-10), inspect to determine the serial number of the
oxygen cylinder assemblies installed in the airplane. The serial
number is stamped into the steel cylinder near the neck. A review of
airplane records is acceptable in lieu of this inspection if the
serial numbers of the oxygen cylinder assemblies can be conclusively
determined from that review. For any oxygen cylinder assembly that
has a serial number identified in Table 3 of this AD: Remove it from
the airplane before further flight.
