ACTION: Final rule.
AGENCY:
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
It has been reported that with the existing
configuration, a certain failure could cause
overspeed of the gas generator rotor resulting
in uncontained burst of the turbine liberating
high-energy fragments.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective April
16, 2007. The Director of the Federal
Register approved the incorporation by
reference of certain publications listed
in this AD as of April 16, 2007.

SUPPLEMENTARY INFORMATION:
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
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
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
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on December 18, 2006 (71 FR
75684). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states that:
It has been reported that with the existing
configuration, a certain failure could cause
overspeed of the gas generator rotor resulting
in uncontained burst of the turbine liberating
high-energy fragments. The occurrence that
the high-energy fragments would be
uncontained is considered a potentially
dangerous situation which requires
imperative corrective action. The purpose of
the modification, which has been made
mandatory, is to limit gas generator speed
during an acceleration towards overspeed by
installation of a modified Electronic Control
Unit (ECU) and Drain Valve. In addition, the
modification also renders the exhaust gas
temperature (EGT) control function
compliant with the certificated
specifications. In operation, if EGT exceeds
the certificated limit value, turbine blade
shedding could occur.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
E:\FR\FM\12MRR1.SGM
12MRR1
Federal Register / Vol. 72, No. 47 / Monday, March 12, 2007 / Rules and Regulations
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
described in a separate paragraph of the
AD, and take precedence over the
actions copied from the MCAI.
Costs of Compliance
Based on the service information, we
estimate that this AD will affect about
3 products of U.S. registry. We also
estimate that it will take about 10 workhours per product to comply with this
AD. The average labor rate is $80 per
work-hour. Required parts will cost
about $1,000 per product. Where the
service information lists required parts
costs that are covered under warranty,
we have assumed that there will be no
charge for these costs. As we do not
control warranty coverage for affected
parties, some parties may incur costs
higher than estimated here. Based on
these figures, we estimate the cost of the
AD on U.S. operators to be $5,400 or
$1,800 per product.
hsrobinson on PROD1PC76 with RULES
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;
VerDate Aug<31>2005
17:49 Mar 09, 2007
Jkt 211001
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.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://dms.dot.gov; or in
person at the Docket Management
Facility between 9 a.m. and 5 p.m.,
Monday through Friday, except Federal
holidays. The AD docket contains the
NPRM, the regulatory evaluation, any
comments received, and other
information. The street address for the
Docket Office (telephone (800) 647–
5227) is in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.

ACTION: Final rule.
SUMMARY: The Food and Drug
Administration (FDA) and the Health
Resources and Services Administration
(HRSA) are amending their regulations
to include as part of an organ those
blood vessels recovered with the organ
that are intended for use in organ
transplantation (HRSA regulation); and
to exclude such blood vessels from the
definition of human cells, tissues, or
cellular or tissue-based products (HCT/
Ps) (FDA regulation). The purpose of
this final rule is to amend the
regulations so that blood vessels
recovered with organs and intended for
use in organ transplantation, and
labeled as such, are governed by the
regulations pertaining to organs. The
regulation of other recovered blood
vessels remains unchanged. We (HRSA
and FDA) believe that this change will
eliminate the burden resulting from an
organ procurement organization’s efforts
to comply with both FDA and HRSA
rules with respect to blood vessels (FDA
jurisdiction) and organs (HRSA
jurisdiction).

This rule is effective on April 11,
2007.

SUPPLEMENTARY INFORMATION:
I. Introduction
HRSA oversees transplantation of
organs through the Organ Procurement
and Transplantation Network (OPTN),
which sets policies related to the
procurement, transplantation, and
allocation of human organs (see 42 CFR
part 121). FDA currently regulates blood
vessels. However, FDA does not regulate
vascularized human organs (see 21 CFR
1270.3(j)(4) and 1271.3(d)(1)). FDA’s
jurisdiction over blood vessels intended
for use in organ transplantation overlaps
with HRSA’s oversight of the OPTN.
There is a routine practice of
recovering blood vessels intended for
use in organ transplantation during
organ procurement and using such
blood vessels to connect donor organ
and recipient vessels. Blood vessels
intended for use in organ
transplantation are recovered with
human organs by Organ Procurement
Organizations (OPOs) and stored for use
at transplant centers. Both OPOs and
transplant centers are already subject to
HRSA oversight because of their organ
procurement and transplantation
activities. The application of both HRSA
and FDA regulatory requirements to
these facilities in relation to organs and
blood vessels procured for use in organ
transplantation is not supported by a
need for such dual oversight. In order to
avoid the duplication of efforts and
reduce the burden on affected facilities,
this final rule transfers from FDA to
HRSA jurisdiction over blood vessels
intended and labeled for use in organ
transplantation. This final rule does not
affect the regulation of blood vessels
intended for transplantation that do not
involve organ transplantation.
Jurisdiction over such blood vessels
remains with FDA.
Under this final rule, blood vessels
labeled and intended solely for use in
organ transplantation will be subject to
HRSA requirements in 42 CFR part 121
and any enforceable OPTN policies
established under 42 CFR part 121. To
be regulated under HRSA requirements,
such blood vessels intended for use in
organ transplantation must be labeled
‘‘For use in organ transplantation only.’’
However, they are not required to be
attached to the organ(s), transplanted
simultaneously with such organ(s) to
the same recipient, or transplanted with
the organ(s) from the same donor. For
example, occasionally blood vessels not
used immediately for the
transplantation of a donated organ are
stored for a number of days and
subsequently used to modify the organ
transplant in the same recipient or to
accomplish transplantation in the

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
It has been reported that with the existing configuration, a
certain failure could cause overspeed of the gas generator rotor
resulting in uncontained burst of the turbine liberating high-energy
fragments.
We are issuing this AD to require actions to correct the unsafe
condition on these products.

SUPPLEMENTARY INFORMATION:
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
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on December 18, 2006
(71 FR 75684). That NPRM proposed to correct an unsafe condition for
the specified products. The MCAI states that:
It has been reported that with the existing configuration, a
certain failure could cause overspeed of the gas generator rotor
resulting in uncontained burst of the turbine liberating high-energy
fragments. The occurrence that the high-energy fragments would be
uncontained is considered a potentially dangerous situation which
requires imperative corrective action. The purpose of the
modification, which has been made mandatory, is to limit gas
generator speed during an acceleration towards overspeed by
installation of a modified Electronic Control Unit (ECU) and Drain
Valve. In addition, the modification also renders the exhaust gas
temperature (EGT) control function compliant with the certificated
specifications. In operation, if EGT exceeds the certificated limit
value, turbine blade shedding could occur.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
[[Page 10921]]
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are described in a separate paragraph of the AD, and take precedence
over the actions copied from the MCAI.
Costs of Compliance
Based on the service information, we estimate that this AD will
affect about 3 products of U.S. registry. We also estimate that it will
take about 10 work-hours per product to comply with this AD. The
average labor rate is $80 per work-hour. Required parts will cost about
$1,000 per product. Where the service information lists required parts
costs that are covered under warranty, we have assumed that there will
be no charge for these costs. As we do not control warranty coverage
for affected parties, some parties may incur costs higher than
estimated here. Based on these figures, we estimate the cost of the AD
on U.S. operators to be $5,400 or $1,800 per product.
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 a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at https://
dms.dot.gov; or in person at the Docket Management Facility between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket contains the NPRM, the regulatory evaluation, any comments
received, and other information. The street address for the 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:
2007-05-20 Microturbo: Amendment 39-14981. Docket No. FAA-2006-
24846; Directorate Identifier 2006-NE-21-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective April
16, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Microturbo Saphir 20 Models 095 Auxiliary
Power Units (APU) installed on, but not limited to, Eurocopter AS
332C, AS 332L, AS 332L1, and AS 332L2 helicopters.
Reason
(d) Direction Generale De l'Aviation Civile Airworthiness
Directive F-2005-146, dated August 17, 2005, states:
It has been reported that with the existing configuration, a
certain failure could cause overspeed of the gas generator rotor
resulting in uncontained burst of the turbine liberating high-energy
fragments. The occurrence that the high-energy fragments would be
uncontained is considered a potentially dangerous situation which
requires imperative corrective action. The purpose of the
modification, which has been made mandatory, is to limit gas
generator speed during an acceleration towards overspeed by
installation of a modified Electronic Control Unit (ECU) and Drain
Valve. In addition, the modification also renders the exhaust gas
temperature (EGT) control function compliant with the certificated
specifications. In operation, if EGT exceeds the certificated limit
value, turbine blade shedding could occur.
Actions and Compliance
(e) Unless already done, do the following actions except as stated
in paragraph (f) below.
(1) Within 60 days after the effective date of this AD, replace the
existing ECU and drain valve.
(2) Follow paragraph 2. of Accomplishment Instructions of
Microturbo Alert Service Bulletin (ASB) No. 095-49A11, Edition 2, dated
October 7, 2005, to do these actions.
FAA AD Differences
(f) This AD differs from the mandatory continuing airworthiness
information (MCAI) and/ or service information as follows:
(1) The MCAI issued by an airworthiness authority of another
country refers to Microturbo ASB No. 095-49A11, dated July 27, 2005.
(2) This AD refers to Edition 2 of that ASB, dated October 7, 2005,
which contains revised torque values.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Boston
Aircraft Certification Office, FAA, has the authority to approve AMOCs
for this AD, if requested using the procedures found in 14 CFR 39.19.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority (or
their delegated agent). You are required to assure the product is
airworthy before it is returned to service.
(3) Reporting Requirements: None.
