Federal Register / Vol. 72, No. 91 / Friday, May 11, 2007 / Rules and Regulations
Affected ADs
(b) None.
(3) Reporting Requirements: For any
reporting requirement in this AD, under the
provisions of the Paperwork Reduction Act,
the Office of Management and Budget (OMB)
has approved the information collection
requirements and has assigned OMB Control
Number 2120–0056.
Applicability
(c) This AD applies to Turbomeca Arriel
2B1 turboshaft engines. These engines are
installed on, but not limited to, Eurocopter
AS 350 B3 and EC 130 B4 single-engine
helicopters.
Reason
(d) European Aviation Safety Agency
(EASA) AD No. 2007–0085, dated April 2,
2007, states:
Two cases of flameout have been reported
on Arriel 2B1 engines: one when lowering
collective pitch on ground at landing and one
when switching from Flight Position to idle
Position on ground.
Both flameout events are explained as
follows:
In case of stepper motor loss of steps to a
value below the ‘‘level 1 failure’’ detection
threshold, the fuel flow of the anti-flameout
limit can be reduced.
The reduction can be sufficient to cause an
engine flameout when decreasing rapidly the
demand for power (it can therefore also
happen in-flight).
This condition may lead to an
uncommanded in-flight shutdown. On a
single-engine helicopter, the result may be an
emergency autorotation landing or, at worst,
an accident.
To prevent this, software version 5.02 (TU
144C) increases the anti-flameout limit in the
event of small stepper motor loss of steps
(below the ‘‘level 1 failure’’ detection
threshold).
Actions and Compliance
(e) Unless already done, do the following
actions.
(1) As soon as practicable, but no later than
August 31, 2007, modify the digital
electronic control unit (DECU) by
downloading the TU144C software version
5.02, using the Instructions to be
Incorporated of Turbomeca Mandatory
Service Bulletin (MSB) No. 292 73 2144,
dated January 5, 2007.
(2) Send Turbomeca the DECU replacement
compliance certificate, as specified in
paragraph 2D(1)(a)3 of Turbomeca MSB No.
292 73 2144, dated January 5, 2007.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. The streamlined
E:\FR\FM\11MYR1.SGM
11MYR1
Federal Register / Vol. 72, No. 91 / Friday, May 11, 2007 / Rules and Regulations
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 Civil Aviation Authority of New
Zealand, which is the aviation authority
for New Zealand, has issued DCA/
750XL/12A, drafted: March 27, 2007,
effective date: March 29, 2007 (referred
to after this as ‘‘the MCAI’’), to correct
an unsafe condition for the specified
products. The MCAI states:
* * *failure of the Autopilot System
Computer resulting in the possibility of an
out of trim condition, which may lead to loss
of aircraft control * * *
The MCAI requires disconnection of
the autopilot, inspection of the pitch
servo, and modification of the autopilot
pitch trim circuit. You may obtain
further information by examining the
MCAI in the AD docket.

Relevant Service Information
Pacific Aerospace Limited has issued
Mandatory Service Bulletin PACSB/XL/
025, dated March 5, 2007. The actions
described in this service information are
intended to correct the unsafe condition
identified in the MCAI.
FAA’s Determination and Requirements
of the AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are issuing this
AD because we evaluated all
information provided by the State of
Design Authority and determined the
unsafe condition exists and is likely to
exist or develop on other products of the
same type design.
Currently within the United States
there are no known Pacific Aerospace
Limited Model 750XL airplanes with an
S-Tec X55 autopilot system installed.
VerDate Aug<31>2005
18:01 May 10, 2007
Jkt 211001
There are no products of this type
currently registered in the United States.
However, this rule is necessary to
ensure that the described unsafe
condition is addressed if any of these
products are placed on the U.S. Register
in the future.
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
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 FAA policies.
Any such differences are highlighted in
a Note within the AD.
Comments Invited
Since there are currently no domestic
operators of this product, notice and
opportunity for public comment before
issuing this AD are unnecessary.
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–2007–27859;
Directorate Identifier 2007–CE–033–
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://
dms.dot.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,
PO 00000
Frm 00007
Fmt 4700
Sfmt 4700
26717
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 that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
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.

FAA AD Differences
pwalker on PROD1PC71 with RULES
Note: This AD differs from the MCAI and/
or service information as follows:
(1) The MCAI requires an interim action of
disconnecting the autopilot following Pacific
Aerospace Limited Alert Service Bulletin
PACSB/XL/001, dated February 16, 2007.
Since there are no products of this type
currently registered in the United States, and
Pacific Aerospace Limited Mandatory Service
Bulletin PACSB/XL/025, dated March 5,
2007, supersedes Pacific Aerospace Limited
Alert Service Bulletin PACSB/XL/001, dated
February 16, 2007, we are not requiring
disconnection of the autopilot. Instead we
require the autopilot comply with the
terminating actions in Pacific Aerospace
Limited Mandatory Service Bulletin PACSB/
XL/025, dated March 5, 2007.
(2) The MCAI allows modification of the
pitch trim circuit within 150 hours time-inservice. Since there are no products of this
type currently registered in the United States,
we are requiring modification of the pitch
trim circuit before a domestic airworthiness
certificate can be issued.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, Small Airplane
Directorate, FAA, has the authority to
approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. The streamlined
[[Page 26717]]
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 Civil Aviation Authority of New Zealand, which is the aviation
authority for New Zealand, has issued DCA/750XL/12A, drafted: March 27,
2007, effective date: March 29, 2007 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states:
* * *failure of the Autopilot System Computer resulting in the
possibility of an out of trim condition, which may lead to loss of
aircraft control * * *
The MCAI requires disconnection of the autopilot, inspection of the
pitch servo, and modification of the autopilot pitch trim circuit. You
may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Pacific Aerospace Limited has issued Mandatory Service Bulletin
PACSB/XL/025, dated March 5, 2007. The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI.
FAA's Determination and Requirements of the AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are issuing this AD because we
evaluated all information provided by the State of Design Authority and
determined the unsafe condition exists and is likely to exist or
develop on other products of the same type design.
Currently within the United States there are no known Pacific
Aerospace Limited Model 750XL airplanes with an S-Tec X55 autopilot
system installed. There are no products of this type currently
registered in the United States. However, this rule is necessary to
ensure that the described unsafe condition is addressed if any of these
products are placed on the U.S. Register in the future.
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
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 FAA policies. Any such differences are
highlighted in a Note within the AD.
Comments Invited
Since there are currently no domestic operators of this product,
notice and opportunity for public comment before issuing this AD are
unnecessary.
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-2007-27859; Directorate
Identifier 2007-CE-033-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://
dms.dot.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 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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends14 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:
2007-10-08 Pacific Aerospace Limited: Amendment 39-15049; Docket No.
FAA-2007-27859; Directorate Identifier 2007-CE-033-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective June 15,
2007.
[[Page 26718]]
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model 750XL airplanes, serial numbers
125, 126, and 127, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 22:
Autopilot.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
* * * failure of the Autopilot System Computer resulting in the
possibility of an out of trim condition, which may lead to loss of
aircraft control* * *
Actions and Compliance
(f) Unless already done, do the following actions before further
flight.
(1) Modify the autopilot pitch trim circuit with additional
protective features following Pacific Aerospace Limited Mandatory
Service Bulletin PACSB/XL/025, dated March 5, 2007.
(2) Inspect the Pitch Servo to confirm part number (P/N) 108-15-
P1 is installed following Pacific Aerospace Limited Mandatory
Service Bulletin PACSB/XL/025, dated March 5, 2007.
(i) If Pitch Servo P/N 108-15-P1 is installed, no further action
is necessary.
(ii) If Pitch Servo P/N 108-15-P1 is not installed, replace the
Pitch Servo with P/N 108-15-P1 following Pacific Aerospace Limited
Mandatory Service Bulletin PACSB/XL/025, dated March 5, 2007.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows:
(1) The MCAI requires an interim action of disconnecting the
autopilot following Pacific Aerospace Limited Alert Service Bulletin
PACSB/XL/001, dated February 16, 2007. Since there are no products
of this type currently registered in the United States, and Pacific
Aerospace Limited Mandatory Service Bulletin PACSB/XL/025, dated
March 5, 2007, supersedes Pacific Aerospace Limited Alert Service
Bulletin PACSB/XL/001, dated February 16, 2007, we are not requiring
disconnection of the autopilot. Instead we require the autopilot
comply with the terminating actions in Pacific Aerospace Limited
Mandatory Service Bulletin PACSB/XL/025, dated March 5, 2007.
(2) The MCAI allows modification of the pitch trim circuit
within 150 hours time-in-service. Since there are no products of
this type currently registered in the United States, we are
requiring modification of the pitch trim circuit before a domestic
airworthiness certificate can be issued.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Small Airplane Directorate, FAA, has the authority to approve AMOCs
