Transportation (DOT).
ACTION: Final rule; request for
comments.
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:
The review of manufacturing process and
service experience has shown that the ALRP–
5 fuel metering pump units released to
service between May 2006 and April 2007
can be vulnerable for seizing. This
vulnerability is demonstrated by occurrence
of aluminum and bronze chips at the filter.
This condition, if not corrected might lead to
seizing of the pump and engine RPM
decrease.
This AD requires actions that are
intended to address the unsafe
condition described in the MCAI, which
could result in low-time pump seizure,
loss of engine fuel flow and engine
power, possibly leading to an
autorotation landing.
DATES: This AD becomes effective
March 24, 2009.
We must receive comments on this
AD by April 20, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2007–0153–E,
dated May 25, 2007 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
jlentini on PROD1PC65 with RULES
The review of manufacturing process and
service experience has shown that the ALRP–
5 fuel metering pump units released to
service between May 2006 and April 2007
can be vulnerable for seizing. This
vulnerability is demonstrated by occurrence
of aluminum and bronze chips at the filter.
This condition, if not corrected might lead to
seizing of the pump and engine RPM
decrease.
This AD requires initial and repetitive
visual inspections of the fine filter in
certain serial number ALRP–5 fuel
metering pumps for aluminum and
bronze chips at the filter, and removal
of the pump from service if the filter
fails the inspection. You may obtain
further information by examining the
MCAI in the AD docket.

Differences Between the AD and the
MCAI or Service Information
We have reviewed the MCAI and, in
general, agree with its substance. But we
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.
FAA’s Determination and Requirements
of This AD
This product has been approved by
the aviation authority of Poland, and is
approved for operation in the United
States. Pursuant to our bilateral
agreement with Poland, 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 the information provided by Poland
and determined the unsafe condition
exists and is likely to exist or develop
on other products of the same type
design. This AD requires initial and
repetitive visual inspections of the fine
filter in certain serial number ALRP–5
fuel metering pumps for aluminum and
bronze chips at the filter, and removal
of the pump from service if the filter
fails the inspection.
FAA’s Determination of the Effective
Date
Since no domestic operators use this
product, notice and opportunity for
public comment before issuing this AD
are unnecessary. Therefore, we are
adopting this regulation immediately.
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–2008–1068;
Directorate Identifier 2008–NE–33–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 with FAA
personnel concerning this AD. Using the
PO 00000
Frm 00023
Fmt 4700
Sfmt 4700

search function of the Web site, anyone
can find and read the comments in any
of our dockets, including, if provided,
the name of the individual who sent the
comment (or signed the comment on
behalf of an association, business, labor
union, etc.). You may review the DOT’s
complete Privacy Act Statement in the
Federal Register published on April 11,
2000 (65 FR 19477–78).
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.

SUPPLEMENTARY INFORMATION:
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2007-0153-E, dated May 25, 2007 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
The review of manufacturing process and service experience has
shown that the ALRP-5 fuel metering pump units released to service
between May 2006 and April 2007 can be vulnerable for seizing. This
vulnerability is demonstrated by occurrence of aluminum and bronze
chips at the filter. This condition, if not corrected might lead to
seizing of the pump and engine RPM decrease.
This AD requires initial and repetitive visual inspections of the
fine filter in certain serial number ALRP-5 fuel metering pumps for
aluminum and bronze chips at the filter, and removal of the pump from
service if the filter fails the inspection. You may obtain further
information by examining the MCAI in the AD docket.

We have reviewed the MCAI and, in general, agree with its
substance. But we 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.
FAA's Determination and Requirements of This AD
This product has been approved by the aviation authority of Poland,
and is approved for operation in the United States. Pursuant to our
bilateral agreement with Poland, 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 the information
provided by Poland and determined the unsafe condition exists and is
likely to exist or develop on other products of the same type design.
This AD requires initial and repetitive visual inspections of the fine
filter in certain serial number ALRP-5 fuel metering pumps for aluminum
and bronze chips at the filter, and removal of the pump from service if
the filter fails the inspection.
FAA's Determination of the Effective Date
Since no domestic operators use this product, notice and
opportunity for public comment before issuing this AD are unnecessary.
Therefore, we are adopting this regulation immediately.
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-2008-1068; Directorate
Identifier 2008-NE-33-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
with FAA personnel concerning this AD. Using the search function of the
Web site, anyone can find and read the comments in any of our dockets,
including, if provided, the name of the individual who sent the comment
(or signed the comment on behalf of an association, business, labor
union, etc.). You may review the DOT's complete Privacy Act Statement
in the Federal Register published on April 11, 2000 (65 FR 19477-78).
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.

Reason
(d) European Aviation Safety Agency (EASA) AD No. 2007-0153-E,
dated May 25, 2007, states:
The review of manufacturing process and service experience has
shown that the ALRP-5 fuel metering pump units released to service
between May 2006 and April 2007 can be vulnerable for seizing. This
vulnerability is demonstrated by occurrence of aluminum and bronze
chips at the filter. This condition, if not corrected might lead to
seizing of the pump and engine RPM decrease.
We are issuing this AD to prevent low-time pump seizure, loss of
engine fuel flow and engine power, possibly leading to an
autorotation landing.
Actions and Compliance
(e) Unless already done, do the following visual inspections
using paragraph (f) of this AD.
Initial Inspection
(1) Visually inspect the fuel metering pump fine filter before
further flight.
Fuel Metering Pumps With More Than 30 Hours Time-In-Service
(2) For fuel metering pumps with more than 30 hours time-in-
service (TIS) on the effective date of this AD, re-inspect the
filter within 5 hours TIS after reaching 50 hours TIS since the
initial inspection specified in paragraph (e)(1) of this AD.
Fuel Metering Pumps With 30 or Fewer Hours Time-In-Service
(3) For fuel metering pumps with 30 or fewer hours TIS on the
effective date of this AD, re-inspect the filter after each flight
day, not to exceed 4 hours TIS between each inspection, until
reaching 30 hours TIS.
(4) Re-inspect the filter within 5 hours TIS after reaching 50
hours TIS since the last inspection specified in paragraph (e)(3) of
this AD.
If Filter Fails Inspection
(5) If the filter fails any inspection, remove the fuel metering
pump from service and install a serviceable fuel metering pump.
(f) Visually inspect the pump fine filter as follows:
(1) Remove the fine filter from the ALRP-5 pump and visually
inspect it. Information on removing the fine filter can be found in
PZL-10W Maintenance Manual, Document No. 19.0.400.
(2) If there is no evidence of any metal chips on the filter,
wash and reinstall the filter, and vent the fuel system.
(3) If metal chips are found on the filter, evaluate the chips
as follows:
(i) Aluminum or bronze chips are not allowed.
(ii) Metallic particles seen as reflection of light are
allowable in maximum quantity of 10 per filter segment (row) but not
more than 30 for the entire filter.
Definition
(g) For the purpose of this AD, a serviceable fuel metering pump
is one that does not have a serial number listed in this AD, is one
that has successfully completed the inspections required by this AD,
or is one listed in this AD that has been repaired since being
listed in WSK Obligatory Bulletin No. E-19W123/DOA/2007, dated May
2007.
