service any propeller that has 10,000
hours or more total TIS, or that has an
unknown total TIS. Also, this AD
requires initial and repetitive propeller
blade inspections for damage, and repair
if necessary. This AD results from
testing by the manufacturer that
identified stress conditions that affect
the fatigue life and damage tolerance of
C406 and C409 propellers, when
installed on TCM IO–520, TSIO–520, or
IO–550 reciprocating engines. We are
issuing this AD to prevent blade or hub
failure that could result in separation of
a propeller blade and loss of control of
the airplane.
DATES: This AD becomes effective May
17, 2007. The Director of the Federal
Register approved the incorporation by
reference of certain publications listed
in the regulations as of May 17, 2007.

SUPPLEMENTARY INFORMATION: The FAA
proposed to amend 14 CFR part 39 with
a proposed AD. The proposed AD
applies to McCauley Propeller Systems
C406 and C409 propellers, installed on
TCM IO–520, TSIO–520, or IO–550
reciprocating engines. We published the
proposed AD in the Federal Register on
Nov. 16, 2005 (70 FR 69472). That
action proposed to require adding an
operational RPM restriction on the C406
and C409 propellers, and installing an
RPM restriction placard in the cockpit.
We coordinated the proposed placard
placement with the responsible Aircraft
Certification Offices within the Small
Airplane Directorate, and all proposed
installations include a manifold
pressure gauge. That action also
proposed to add a 10,000-hour total
time-in-service (TIS) life limit for these
propellers. That action also proposed to
remove from service any propeller that
has 10,000 hours or more total TIS, or
that has an unknown total TIS. Finally,
that action proposed to require initial
and repetitive propeller blade
inspections for damage, and repair if
necessary.

Examining the AD Docket
You may examine the docket that
contains the AD, any comments
received, and any final disposition in
person at the Docket Management
Facility between 9 a.m. and 5 p.m.,
Monday through Friday, except Federal
holidays. The Docket Office (telephone
(800) 647–5227) is located on the plaza
level of the Department of
Transportation Nassif Building at the
street address stated in ADDRESSES.
Comments will be available in the AD
docket shortly after the DMS receives
them.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Financial Burden and Potential Unsafe
Condition
One commenter states that this AD
will impose a financial burden on
owners and operators of airplanes with
this propeller installation because of the
increased number of inspections and
additional wear on the propeller system
increasing the probability of the
propeller system failing. The commenter
also suggests that stamping a letter on
the propeller model to designate a lifelimited propeller could create a
potentially unsafe condition because the
stamping can create stress risers and if
improperly treated after stamping, could
contribute to corrosion. The commenter
also notes that the airplane model
designations are incorrect and we
omitted one model from the airplane
model listing. Finally, the commenter
asks why we did not immediately
ground the fleet using this propeller
because of the described severity of the
unsafe condition. We partially agree
with the comments. Each is addressed
in turn. The increased inspections
required by this AD are necessary to
resolve the unsafe condition. Owner
operators must maintain their aircraft in
an airworthy condition, which includes
paying for maintenance. We considered
that cost and discussed it in the cost
section below. We did not change the
AD.
This AD will not result in additional
wear and tear on the propellers, or in
increased failures. This AD resolves an
unsafe condition. All actions required
are either performed with the propeller
installed, or coincident with the next
overhaul or major disassembly. An
experienced, appropriately rated
mechanic can do the inspection and
rework without removing the propeller.
We did not change the AD.
PO 00000
Frm 00036
Fmt 4700
Sfmt 4700
The manufacturer carefully
considered where to stamp the life limit
indication to minimize any stress riser.
We have no indications that his choice
was wrong. We did not change the AD.
We agree that this AD should include
additional models. We changed the AD
to include the Beech 35–A33 and 35–
B33. The Beech 35–A33 and 35–B33 are
now included in Applicability
paragraph (c) Table (1).
Grounding the fleet that has the
suspect propellers installed is not
required. The unsafe condition
identified is due to material fatigue. The
actions required by this AD adequately
address the unsafe condition. We did
not change the AD.
Eliminate the Repetitive Inspections of
This AD
Another commenter states that the AD
does not include a terminating action to
eliminate the recurring inspections
necessary to comply with it. Even if an
operator replaces the existing propeller
with a new propeller, the recurring
inspections are necessary as long as the
replacement propeller is one of same
models identified in the airworthiness
directive. Additionally, the commenter
notes that aircraft performance is also a
consideration. This AD will require
operating the engine and propeller
combination in a less than full engine
power regime, which could compromise
safety in particular situations associated
with departures, arrivals and clearing
obstacles. We partially agree.
This AD imposes the RPM and life
limit to correct an unsafe condition. The
recurring inspections are required to
enhance safety. The RPM restriction,
imposed propeller life limit, and
periodic propeller blade inspection/
rework provide a cost effective means to
correct the unsafe condition without
prematurely retiring the propeller. The
RPM restriction does not affect the
engine full power ratings. Takeoff,
climb, and descent values remain
unchanged. Therefore, this AD does not
compromise safety during departures,
arrivals, and in clearing obstacles. We
did not change the AD.
Recall Impacted Propellers
Another commenter believes that the
FAA should require a recall of all
propeller models listed in the AD so the
manufacturer will be responsible for the
cost of repair and replacement. We do
not agree.
The FAA cannot dictate commercial
business decisions related to AD
actions. We identified the unsafe
condition and are imposing appropriate
corrective action. We did not change the
AD.

Federal Register / Vol. 72, No. 70 / Thursday, April 12, 2007 / Rules and Regulations
Extend the Comment Period
Two commenters asked that we
extend the comment period for the
proposed rule to give the general
aviation community added time to
review non-proprietary data used to
substantiate the proposed action and to
make additional comments. We agree,
and extended the comment period to
give the aviation community time to
respond. The comments that we
responded to above include any
additional comments that came in.
Correct Date of Service Bulletin
The proposed rule referenced
McCauley Propeller Systems Alert
Service Bulletin (ASB) No. ASB248,
dated January 17, 2005. The correct date
is April 19, 2005. We changed the AD
to indicate the correct date of the service
bulletin.
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the changes described
previously. We have determined that
these changes will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Costs of Compliance
This AD will affect about 2,350 C406
and C409 propellers installed on
airplanes of U.S. registry. We estimate it
will take three work-hours per propeller
to perform the proposed inspections and
repairs. We also estimate it will take
about 0.5 work-hour to install the
proposed cockpit placard, and about
950 airplanes will require the placard.
The average labor rate is $80 per workhour. A replacement propeller blade set
will cost about $5,200. We estimate 500
propellers in the fleet (or about 21
percent) would require propeller blade
set replacement. Based on these figures,
we estimate the total cost of the AD to
U.S. operators to be $3,202,000.
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 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
18379
under the criteria of the Regulatory
Flexibility Act.
We prepared a summary of the costs
to comply with this AD and placed it in
the AD Docket. You may get a copy of
this summary at the address listed
under ADDRESSES.

AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) to
supersede AD 2006–17–04, which
applies to certain Cessna Aircraft
Company (Cessna) Models 172R, 172S,
182T, T182T, 206H, and T206H
airplanes. AD 2006–17–04 currently
requires you to inspect the two end
fittings on each of the flexible fuel hoses
located in the engine compartment for
the correct torque values, and, if any
incorrect torque values are found during
the inspection, tighten the hose end
fittings to the correct torque values. This
AD results from four reports of loose
fuel lines connected to the fuel servo or
fuel flow transducer. Two reports were
of in-flight engine failure on a Model
T182T airplane. A third report was of
in-flight engine failure on a Model 206H
airplane. A fourth report was of a Model
172S airplane losing engine power on
final approach. Consequently, this AD
would require you to establish the
correct torque values of the end fittings
PO 00000
Frm 00038

Sfmt 4700
on fuel hoses for certain Cessna Models
172R, 172S, 182T, T182T, 206H, and
T206H airplanes. This AD clarifies that
the torque values need to be physically
established and visual inspection only
is not sufficient. We are issuing this AD
to detect and correct potential loss of
fuel flow, which may result in partial or
complete loss of engine power and/or
uncontrolled engine compartment fire

Airworthiness Directives; McCauley Propeller Systems Models
3A32C406/82NDB-X and D3A32C409/82NDB-X Propellers
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
McCauley Propeller Systems models 3A32C406/82NDB-X and D3A32C409/82NDB-
X propellers, installed on Teledyne Continental Motors (TCM) IO-520,
TSIO-520, or IO-550 reciprocating engines. These propellers are herein
referred to as C406 and C409 propellers, respectively. This AD requires
adding an operational revolutions per minute (RPM) restriction on the
C406 and C409 propellers, and installing an RPM restriction placard in
the cockpit. This AD also adds a 10,000-hour total time-in-service
(TIS) life limit for these propellers. This AD also removes from
[[Page 18378]]
service any propeller that has 10,000 hours or more total TIS, or that
has an unknown total TIS. Also, this AD requires initial and repetitive
propeller blade inspections for damage, and repair if necessary. This
AD results from testing by the manufacturer that identified stress
conditions that affect the fatigue life and damage tolerance of C406
and C409 propellers, when installed on TCM IO-520, TSIO-520, or IO-550
reciprocating engines. We are issuing this AD to prevent blade or hub
failure that could result in separation of a propeller blade and loss
of control of the airplane.
DATES: This AD becomes effective May 17, 2007. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of May 17, 2007.
ADDRESSES: You can get the service information identified in this AD
from McCauley Propeller Systems, P.O. Box 7704, Wichita, KS 67277-7704;
telephone (800) 621-7767.

FOR FURTHER INFORMATION CONTACT: Jeff D. Janusz, Aerospace Engineer,
Wichita Aircraft Certification Office, Small Airplane Directorate, 1801
Airport Road, Room 100, Wichita, KS 67209, telephone: 316-946-4148,
fax: 316-946-4107.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed AD. The proposed AD applies to McCauley Propeller
Systems C406 and C409 propellers, installed on TCM IO-520, TSIO-520, or
IO-550 reciprocating engines. We published the proposed AD in the
Federal Register on Nov. 16, 2005 (70 FR 69472). That action proposed
to require adding an operational RPM restriction on the C406 and C409
propellers, and installing an RPM restriction placard in the cockpit.
We coordinated the proposed placard placement with the responsible
Aircraft Certification Offices within the Small Airplane Directorate,
and all proposed installations include a manifold pressure gauge. That
action also proposed to add a 10,000-hour total time-in-service (TIS)
life limit for these propellers. That action also proposed to remove
from service any propeller that has 10,000 hours or more total TIS, or
that has an unknown total TIS. Finally, that action proposed to require
initial and repetitive propeller blade inspections for damage, and
repair if necessary.
Examining the AD Docket
You may examine the docket that contains the AD, any comments
received, and any final disposition in person at the Docket Management
Facility between 9 a.m. and 5 p.m., Monday through Friday, except
Federal holidays. The Docket Office (telephone (800) 647-5227) is
located on the plaza level of the Department of Transportation Nassif
Building at the street address stated in ADDRESSES. Comments will be
available in the AD docket shortly after the DMS receives them.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Financial Burden and Potential Unsafe Condition
One commenter states that this AD will impose a financial burden on
owners and operators of airplanes with this propeller installation
because of the increased number of inspections and additional wear on
the propeller system increasing the probability of the propeller system
failing. The commenter also suggests that stamping a letter on the
propeller model to designate a life-limited propeller could create a
potentially unsafe condition because the stamping can create stress
risers and if improperly treated after stamping, could contribute to
corrosion. The commenter also notes that the airplane model
designations are incorrect and we omitted one model from the airplane
model listing. Finally, the commenter asks why we did not immediately
ground the fleet using this propeller because of the described severity
of the unsafe condition. We partially agree with the comments. Each is
addressed in turn. The increased inspections required by this AD are
necessary to resolve the unsafe condition. Owner operators must
maintain their aircraft in an airworthy condition, which includes
paying for maintenance. We considered that cost and discussed it in the
cost section below. We did not change the AD.
This AD will not result in additional wear and tear on the
propellers, or in increased failures. This AD resolves an unsafe
condition. All actions required are either performed with the propeller
installed, or coincident with the next overhaul or major disassembly.
An experienced, appropriately rated mechanic can do the inspection and
rework without removing the propeller. We did not change the AD.
The manufacturer carefully considered where to stamp the life limit
indication to minimize any stress riser. We have no indications that
his choice was wrong. We did not change the AD.
We agree that this AD should include additional models. We changed
the AD to include the Beech 35-A33 and 35-B33. The Beech 35-A33 and 35-
B33 are now included in Applicability paragraph (c) Table (1).
Grounding the fleet that has the suspect propellers installed is
not required. The unsafe condition identified is due to material
fatigue. The actions required by this AD adequately address the unsafe
condition. We did not change the AD.
Eliminate the Repetitive Inspections of This AD
Another commenter states that the AD does not include a terminating
action to eliminate the recurring inspections necessary to comply with
it. Even if an operator replaces the existing propeller with a new
propeller, the recurring inspections are necessary as long as the
replacement propeller is one of same models identified in the
airworthiness directive. Additionally, the commenter notes that
aircraft performance is also a consideration. This AD will require
operating the engine and propeller combination in a less than full
engine power regime, which could compromise safety in particular
situations associated with departures, arrivals and clearing obstacles.
We partially agree.
This AD imposes the RPM and life limit to correct an unsafe
condition. The recurring inspections are required to enhance safety.
The RPM restriction, imposed propeller life limit, and periodic
propeller blade inspection/rework provide a cost effective means to
correct the unsafe condition without prematurely retiring the
propeller. The RPM restriction does not affect the engine full power
ratings. Takeoff, climb, and descent values remain unchanged.
Therefore, this AD does not compromise safety during departures,
arrivals, and in clearing obstacles. We did not change the AD.
Recall Impacted Propellers
Another commenter believes that the FAA should require a recall of
all propeller models listed in the AD so the manufacturer will be
responsible for the cost of repair and replacement. We do not agree.
The FAA cannot dictate commercial business decisions related to AD
actions. We identified the unsafe condition and are imposing
appropriate corrective action. We did not change the AD.
[[Page 18379]]
Extend the Comment Period
Two commenters asked that we extend the comment period for the
proposed rule to give the general aviation community added time to
review non-proprietary data used to substantiate the proposed action
and to make additional comments. We agree, and extended the comment
period to give the aviation community time to respond. The comments
that we responded to above include any additional comments that came
in.
Correct Date of Service Bulletin
The proposed rule referenced McCauley Propeller Systems Alert
Service Bulletin (ASB) No. ASB248, dated January 17, 2005. The correct
date is April 19, 2005. We changed the AD to indicate the correct date
of the service bulletin.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD will affect about 2,350 C406 and C409 propellers installed
on airplanes of U.S. registry. We estimate it will take three work-
hours per propeller to perform the proposed inspections and repairs. We
also estimate it will take about 0.5 work-hour to install the proposed
cockpit placard, and about 950 airplanes will require the placard. The
average labor rate is $80 per work-hour. A replacement propeller blade
set will cost about $5,200. We estimate 500 propellers in the fleet (or
about 21 percent) would require propeller blade set replacement. Based
on these figures, we estimate the total cost of the AD to U.S.
operators to be $3,202,000.
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 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
