Alternative Methods of Compliance
DEPARTMENT OF TRANSPORTATION
(g) You must perform these mandatory
inspections using the TLS and the applicable
Engine Manual unless you receive approval
to use an alternative method of compliance
under paragraph (h) of this AD. Section 43.16
of the Federal Aviation Regulations (14 CFR
43.16) may not be used to approve alternative
methods of compliance or adjustments to the
times in which these inspections must be
performed.
(h) The Manager, Engine Certification
Office, has the authority to approve
alternative methods of compliance for this
AD if requested using the procedures found
in 14 CFR 39.19.
Maintaining Records of the Mandatory
Inspections
(i) You have met the requirements of this
AD by using a TLS of the manufacturer’s
engine manual changed as specified in
paragraph (f) of this AD, and, for air carriers
operating under part 121 of the Federal
Aviation Regulations (14 CFR part 121), by
modifying your continuous airworthiness
maintenance plan to reflect those changes.
You must maintain records of the mandatory
inspections that result from those changes to
the TLS according to the regulations
governing your operation. You do not need
to record each piece-part inspection as
compliance to this AD. For air carriers
operating under part 121, you may use either
the system established to comply with
section 121.369 or use an alternative system
that your principal maintenance inspector
has accepted if that alternative system:
(1) Includes a method for preserving and
retrieving the records of the inspections
resulting from this AD; and
(2) Meets the requirements of section
121.369(c); and
(3) Maintains the records either
indefinitely or until the work is repeated.
(j) These recordkeeping requirements apply
only to the records used to document the
mandatory inspections required as a result of
revising the TLS as specified in paragraph (f)
of this AD, and do not alter or amend the
recordkeeping requirements for any other AD
or regulatory requirement.

Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule; request for
comments.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD) for
Dowty Propellers Type R321/4–82–F/8,
R324/4–82–F/9, R333/4–82–F/12, and
R334/4–82–F/13 propeller assemblies.
That AD currently requires initial and
repetitive ultrasonic inspections of
propeller hubs, part number (P/N)
660709201. This AD requires the same
initial and repetitive ultrasonic
inspections, but makes some needed
corrections. This AD results from
comments received on AD 2005–20–12.
We are issuing this AD to prevent
propeller hub failure due to cracks in
the hub, which could result in loss of
control of the airplane.
DATES: Effective December 27, 2005. The
Director of the Federal Register
previously approved the incorporation
by reference of certain publications
listed in the regulations as of July 27,
2004 (69 FR 34560, June 22, 2004) and
October 28, 2005 (70 FR 59647, October
13, 2005).
We must receive any comments on
this AD by February 10, 2006.

SUPPLEMENTARY INFORMATION: On
September 26, 2005, we issued AD
2005–20–12, Amendment 39–14306 (70
FR 59647, October 13, 2005). That AD
requires initial and repetitive ultrasonic
inspections of propeller hubs, P/N
660709201. That AD was the result of a
report of a hub separation on a CASA
212 airplane. That condition, if not
corrected, could result in propeller hub
failure due to cracks in the hub, which
could result in loss of control of the
airplane.
Comments
We provided the public the
opportunity to comment on AD 2005–
20–12. We have considered the
comments received.
Allow Use of Appendix D
One commenter, the manufacturer,
requests we allow operators and
inspectors to also use Appendix D of the
referenced service bulletins. We agree
and added the use of Appendix D to this
AD.
Request To Include Flight Cycle Limit
The same commenter requests we
include a flight cycle limit in the
repetitive inspection compliance for
R334/4–82–F/13 propeller assemblies,
to be consistent with the service
bulletin. We agree and changed the
repetitive ultrasonic inspection
compliance to ‘‘within 300 flight hours
time-since-last-inspection or 300 flight
cycles-since-last inspection, whichever
occurs sooner’’.
Request To Correct the Manufacturer’s
Name
The same commenter requests we
correct their former name of Dowty
Aerospace Propellers, to their current
name of Dowty Propellers. We agree and
made the name change.
Request To Clarify Initial Inspection
Compliance
The same commenter requests we
revise paragraph (h) of AD 2005–20–12
to clarify that operators that previously
complied with the initial inspection in
paragraph (f) do not have to comply a
second time to that initial inspection.
We agree. For clarification, we revised
the paragraph, moved it closer to the
Compliance heading, and codified it as
paragraph (f).

Federal Register / Vol. 70, No. 237 / Monday, December 12, 2005 / Rules and Regulations
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.
Special Flight Permits Paragraph
Removed
Paragraph (l) of the current AD, AD
2005–20–12, contains a paragraph
pertaining to special flight permits.
Even though this final rule does not
contain a similar paragraph, we have
made no changes with regard to the use
of special flight permits to operate the
airplane to a repair facility to do the
work required by this AD. In July 2002,
we published a new Part 39 that
contains a general authority regarding
special flight permits and airworthiness
directives; see Docket No. FAA–2004–
8460, Amendment 39–9474 (69 FR
47998, July 22, 2002). Thus, when we
now supersede ADs we will not include
a specific paragraph on special flight
permits unless we want to limit the use
of that general authority granted in
section 39.23.
Relevant Service Information
We have reviewed and approved the
technical contents of Dowty Propellers
Alert MSB No. 61–1119, Revision 4,
dated September 14, 2005, that specifies
initial and repetitive ultrasonic
inspections of the rear wall of the rear
half of the propeller hub for cracks on
Type R334/4–82–F/13 propeller
assemblies used on CASA 212 airplanes.
The CAA classified this service bulletin
as mandatory and issued CAA UK AD
No. G–2005–0027, dated September 8,
2005, to assure the airworthiness of
these Dowty Propellers in the U.K.
Differences Between This AD and the
Service Information
Although Appendix A of Alert MSB
No. 61–1119, Revision 4, dated
September 14, 2005, requires reporting
the inspection data to Dowty Propellers,
this AD requires that you report the data
to the Boston Aircraft Certification
Office of the FAA.
Bilateral Airworthiness Agreement
These propeller models are
manufactured in the U.K. and are type
certificated for operation in the United
States under the provisions of section
21.29 of the Federal Aviation
Regulations (14 CFR 21.29) and the
applicable bilateral airworthiness
agreement. Under this bilateral
airworthiness agreement, the CAA has
kept the FAA informed of the situation
described above. We have examined the
VerDate Aug<31>2005
15:45 Dec 09, 2005
Jkt 208001
73365
findings of the CAA, reviewed all
available information, and determined
that AD action is necessary for products
of this type design that are certificated
for operation in the United States.
that good cause exists for making this
amendment effective in less than 30
days.
FAA’s Determination and Requirements
of This AD
The unsafe condition described
previously is likely to exist or develop
on other Dowty Propellers Type R321/
4–82–F/8, R324/4–82–F/9, R333/4–82–
F/12, and R334/4–82–F/13 propeller
assemblies of the same type design. We
are issuing this AD to prevent propeller
hub failure due to cracks in the hub,
which could result in loss of control of
the airplane. This AD requires:
• Within 10 flight hours (FH) time-inservice (TIS) or 20 days after the
effective date of this AD, whichever
occurs earlier, performing an initial
ultrasonic inspection of the rear halves
of propeller hubs P/N 660709201, that
are installed in Type R334/4–82–F/13
propeller assemblies, and;
• Within 50 FH TIS or 60 days after
the effective date of this AD, whichever
occurs earlier, performing an initial
ultrasonic inspection of the rear halves
of propeller hubs P/N 660709201, that
are installed in Type R321/4–82–F/8,
R324/4–82–F/9, and R333/4–82–F/12
propeller assemblies, and;
• Within 300 FH time-since-lastinspection (TSLI) or 300 flight cyclessince-last-inspection, whichever occurs
sooner, performing a repetitive
ultrasonic inspection of the rear halves
of propeller hubs P/N 660709201, that
are installed in Type R334/4–82–F/13
propeller assemblies, and;
• Within 1,000 FH TSLI performing a
repetitive ultrasonic inspection of the
rear halves of propeller hubs P/N
660709201, that are installed in Type
R321/4–82–F/8, R324/4–82–F/9, and
R333/4–82–F/12 propeller assemblies,
and;
• If not already done, performing an
ultrasonic inspection of the rear halves
of propeller hubs P/N 660709201, that
are installed in Type R321/4–82–F/8,
R324/4–82–F/9, R333/4–82–F/12, and
R334/4–82–F/13 propeller assemblies
that are in storage before installing the
propeller assembly onto an airplane.
You must use the service information
specified in Table 2 of this AD to
perform the inspections required by this
AD.
This AD is a final rule that involves
requirements affecting flight safety and
was not preceded by notice and an
opportunity for public comment;
however, we invite you to submit any
written relevant data, views, or
arguments regarding this AD. Send your
comments to an address listed under
ADDRESSES. Include ‘‘AD Docket No.
2001–NE–50–AD’’ in the subject line of
your comments. If you want us to
acknowledge receipt of your mailed
comments, send us a self-addressed,
stamped postcard with the docket
number written on it; we will datestamp your postcard and mail it back to
you. We specifically invite comments
on the overall regulatory, economic,
environmental, and energy aspects of
the rule that might suggest a need to
modify it. If a person contacts us
verbally, and that contact relates to a
substantive part of this AD, we will
summarize the contact and place the
summary in the docket. We will
consider all comments received by the
closing date and may amend the AD in
light of those comments.
FAA’s Determination of the Effective
Date
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we have found that notice and
opportunity for public comment before
issuing this AD are impracticable, and

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.

Airworthiness Directives; Dowty Propellers Type R321/4-82-F/8,
R324/4-82-F/9, R333/4-82-F/12, and R334/4-82-F/13 Propeller Assemblies
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD) for Dowty Propellers Type R321/4-82-F/8, R324/4-82-F/9, R333/4-82-
F/12, and R334/4-82-F/13 propeller assemblies. That AD currently
requires initial and repetitive ultrasonic inspections of propeller
hubs, part number (P/N) 660709201. This AD requires the same initial
and repetitive ultrasonic inspections, but makes some needed
corrections. This AD results from comments received on AD 2005-20-12.
We are issuing this AD to prevent propeller hub failure due to cracks
in the hub, which could result in loss of control of the airplane.
DATES: Effective December 27, 2005. The Director of the Federal
Register previously approved the incorporation by reference of certain
publications listed in the regulations as of July 27, 2004 (69 FR
34560, June 22, 2004) and October 28, 2005 (70 FR 59647, October 13,
2005).
We must receive any comments on this AD by February 10, 2006.
ADDRESSES: Use one of the following addresses to submit comments on
this AD:

SUPPLEMENTARY INFORMATION: On September 26, 2005, we issued AD 2005-20-
12, Amendment 39-14306 (70 FR 59647, October 13, 2005). That AD
requires initial and repetitive ultrasonic inspections of propeller
hubs, P/N 660709201. That AD was the result of a report of a hub
separation on a CASA 212 airplane. That condition, if not corrected,
could result in propeller hub failure due to cracks in the hub, which
could result in loss of control of the airplane.
Comments
We provided the public the opportunity to comment on AD 2005-20-12.
We have considered the comments received.
Allow Use of Appendix D
One commenter, the manufacturer, requests we allow operators and
inspectors to also use Appendix D of the referenced service bulletins.
We agree and added the use of Appendix D to this AD.
Request To Include Flight Cycle Limit
The same commenter requests we include a flight cycle limit in the
repetitive inspection compliance for R334/4-82-F/13 propeller
assemblies, to be consistent with the service bulletin. We agree and
changed the repetitive ultrasonic inspection compliance to ``within 300
flight hours time-since-last-inspection or 300 flight cycles-since-last
inspection, whichever occurs sooner''.
Request To Correct the Manufacturer's Name
The same commenter requests we correct their former name of Dowty
Aerospace Propellers, to their current name of Dowty Propellers. We
agree and made the name change.
Request To Clarify Initial Inspection Compliance
The same commenter requests we revise paragraph (h) of AD 2005-20-
12 to clarify that operators that previously complied with the initial
inspection in paragraph (f) do not have to comply a second time to that
initial inspection. We agree. For clarification, we revised the
paragraph, moved it closer to the Compliance heading, and codified it
as paragraph (f).
[[Page 73365]]
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.
Special Flight Permits Paragraph Removed
Paragraph (l) of the current AD, AD 2005-20-12, contains a
paragraph pertaining to special flight permits. Even though this final
rule does not contain a similar paragraph, we have made no changes with
regard to the use of special flight permits to operate the airplane to
a repair facility to do the work required by this AD. In July 2002, we
published a new Part 39 that contains a general authority regarding
special flight permits and airworthiness directives; see Docket No.
FAA-2004-8460, Amendment 39-9474 (69 FR 47998, July 22, 2002). Thus,
when we now supersede ADs we will not include a specific paragraph on
special flight permits unless we want to limit the use of that general
authority granted in section 39.23.
Relevant Service Information
We have reviewed and approved the technical contents of Dowty
Propellers Alert MSB No. 61-1119, Revision 4, dated September 14, 2005,
that specifies initial and repetitive ultrasonic inspections of the
rear wall of the rear half of the propeller hub for cracks on Type
R334/4-82-F/13 propeller assemblies used on CASA 212 airplanes. The CAA
classified this service bulletin as mandatory and issued CAA UK AD No.
G-2005-0027, dated September 8, 2005, to assure the airworthiness of
these Dowty Propellers in the U.K.
Differences Between This AD and the Service Information
Although Appendix A of Alert MSB No. 61-1119, Revision 4, dated
September 14, 2005, requires reporting the inspection data to Dowty
Propellers, this AD requires that you report the data to the Boston
Aircraft Certification Office of the FAA.
Bilateral Airworthiness Agreement
These propeller models are manufactured in the U.K. and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Under this bilateral
airworthiness agreement, the CAA has kept the FAA informed of the
situation described above. We have examined the findings of the CAA,
reviewed all available information, and determined that AD action is
necessary for products of this type design that are certificated for
operation in the United States.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other Dowty Propellers Type R321/4-82-F/8, R324/4-82-F/9,
R333/4-82-F/12, and R334/4-82-F/13 propeller assemblies of the same
type design. We are issuing this AD to prevent propeller hub failure
due to cracks in the hub, which could result in loss of control of the
airplane. This AD requires:
Within 10 flight hours (FH) time-in-service (TIS) or 20
days after the effective date of this AD, whichever occurs earlier,
performing an initial ultrasonic inspection of the rear halves of
propeller hubs P/N 660709201, that are installed in Type R334/4-82-F/13
propeller assemblies, and;
Within 50 FH TIS or 60 days after the effective date of
this AD, whichever occurs earlier, performing an initial ultrasonic
inspection of the rear halves of propeller hubs P/N 660709201, that are
installed in Type R321/4-82-F/8, R324/4-82-F/9, and R333/4-82-F/12
propeller assemblies, and;
Within 300 FH time-since-last-inspection (TSLI) or 300
flight cycles-since-last-inspection, whichever occurs sooner,
performing a repetitive ultrasonic inspection of the rear halves of
propeller hubs P/N 660709201, that are installed in Type R334/4-82-F/13
propeller assemblies, and;
Within 1,000 FH TSLI performing a repetitive ultrasonic
inspection of the rear halves of propeller hubs P/N 660709201, that are
installed in Type R321/4-82-F/8, R324/4-82-F/9, and R333/4-82-F/12
propeller assemblies, and;
If not already done, performing an ultrasonic inspection
of the rear halves of propeller hubs P/N 660709201, that are installed
in Type R321/4-82-F/8, R324/4-82-F/9, R333/4-82-F/12, and R334/4-82-F/
13 propeller assemblies that are in storage before installing the
propeller assembly onto an airplane.
You must use the service information specified in Table 2 of this
AD to perform the inspections required by this AD.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this AD, we have found that notice and opportunity for
public comment before issuing this AD 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 was not preceded by notice and an opportunity for public
comment; however, we invite you to submit any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. 2001-NE-50-AD'' in the
subject line of your comments. If you want us to acknowledge receipt of
your mailed comments, send us a self-addressed, stamped postcard with
the docket number written on it; we will date-stamp your postcard and
mail it back to you. We specifically invite comments on the overall
regulatory, economic, environmental, and energy aspects of the rule
that might suggest a need to modify it. If a person contacts us
verbally, and that contact relates to a substantive part of this AD, we
will summarize the contact and place the summary in the docket. We will
consider all comments received by the closing date and may amend the AD
in light of those comments.
Examining the AD Docket
You may examine the AD Docket (including any comments and service
information), by appointment, between 8 a.m. and 4:30 p.m., Monday
through Friday, except Federal holidays. See ADDRESSES for the

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.
[[Page 73366]]
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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary by
sending a request to us at the address listed under ADDRESSES. Include
``AD Docket No. 2001-NE-50-AD'' in your request.
