ACTION: Final rule; request for
comments.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
McCauley Propeller Systems propeller
assemblies installed on BAE Systems
(Operations) Limited Jetstream model
4100 series airplanes. This AD requires
removing certain propeller hubs from
service at new reduced life limits and
eddy current inspections (ECIs) of the
propeller hub. This AD results from
three reports of cracked propeller hubs.
We are issuing this AD to prevent
cracked propeller hubs, which could
cause failure of the propeller hub, blade
separation, and loss of control of the
airplane.
DATES: This AD becomes effective
December 15, 2005. The Director of the
Federal Register approved the
incorporation by reference of certain
publications listed in the regulations as
of December 15, 2005.
We must receive any comments on
this AD by January 30, 2006.

SUPPLEMENTARY INFORMATION: In August
2003, we issued AD 2003–17–10 which
requires initial and repetitive
fluorescent penetrant inspection or
ultrasonic inspection of propeller blade
retention areas for cracks, replacement
of high time propeller blades, and a
onetime inspection of propeller hubs.
That AD resulted from four earlier
reports of cracks in propeller blade
shanks. Since we issued AD 2003–17–
10, we received three more reports of
cracked hubs. In November 2004, we
issued AD 2004–23–16 which requires a
onetime ECI of the propeller hub for
cracks, and if necessary, replacing the
propeller assembly. That AD also
captured inspection results for the
propeller hubs installed on the Jetstream
model 4100 fleet.
We received field reports that during
taxi and ground maneuvering, certain
airplane operators might be violating the
published and placarded propeller
ground revolutions-per-minute (rpm)
restrictions. Operating in the restricted
rpm range during ground operation can
excite a natural propeller blade
frequency that creates damaging stress
loadings on the propeller blades and
hub. The stress loadings can cause
cracks, leading to propeller structural
failure.
Additionally, some operators use a
water-methanol assist system to provide
more engine power during certain
operating conditions. The operating
procedures for the water-methanol assist
system define an airplane brakes-locked
PO 00000
Frm 00008

condition. Testing has shown that using
the water-methanol assist system with
airplane brakes locked creates propeller
loadings exceeding structural fatigue
limits of the propeller hub. This
condition, if not corrected, could result
in cracked hubs, which could cause
failure of the propeller hub, blade
separation, and loss of control of the
airplane.
Relevant Service Information
We reviewed and approved the
technical contents of McCauley Alert
Service Bulletin (ASB) No. ASB250,
dated September 12, 2005. This ASB
introduces new lower life limits for the
propeller hubs identified in this AD,
and describes ECI procedures for them.
FAA’s Determination and Requirements
of This AD
The unsafe condition described
previously is likely to exist or develop
on other McCauley propeller
assemblies, P/Ns B5JFR36C1101/
114GCA–0, C5JFR36C1102/L114GCA–0,
B5JFR36C1103/114HCA–0, and
C5JFR36C1104/L114HCA–0, installed
on BAE Systems (Operations) Limited
Jetstream model 4100 series airplanes.
We are issuing this AD to prevent
cracked hubs, which could cause failure
of the propeller hub, blade separation,
and loss of control of the airplane. This
AD requires:
• Removing any propeller hub from
service that is currently, or ever was,
operated on an engine with a watermethanol assist system, not later than
6,000 hours time-in-service (TIS).
• Removing any other propeller hub
from service not later than 18,000 hours
TIS.
• Removing any propeller hub from
service that exceeds its life limit on the
effective date of this AD, within 50
hours TIS after the effective date of this
AD.
• That any propeller hub removed
from service after exceeding its life limit
must not be returned to service on any
installation.
• For all installed propeller hubs,
performing an ECI within 200 hours TIS
or 60 days after the effective date of this
AD, whichever occurs first.
• Thereafter, for all installed
propeller hubs with 12,000 or more
hours TIS, performing repetitive ECIs
within 1,800 hours TIS or 12 months,
whichever occurs first.
You must use the service information
described previously to perform the
actions required by this AD. This AD
does not require repetitive inspections
for propeller hubs that ever operated on,
or are currently operating on, engines
with a water-methanol assist system,
E:\FR\FM\30NOR1.SGM
30NOR1
Federal Register / Vol. 70, No. 229 / Wednesday, November 30, 2005 / Rules and Regulations
due to the 6,000 hours TIS hub reduced
life limit.
FAA’s Determination of the Effective
Date
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we found that notice and
opportunity for public comment before
issuing this AD are impracticable. Good
cause exists for making this amendment
effective in less than 30 days.
Comments Invited

Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
VerDate Aug<31>2005
19:03 Nov 29, 2005
Jkt 208001
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 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 at the address listed
under ADDRESSES.

IFR Altitudes; Miscellaneous
Amendments
Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
SUMMARY: This amendment adopts
miscellaneous amendments to the
required IFR (instrument flight rules)
altitudes and changeover points for
certain Federal airways, jet routes, or
direct routes for which a minimum or
maximum en route authorized IFR
altitude is prescribed. This regulatory
action is needed because of changes
occurring in the National Airspace
System. These changes are designed to
provide for the safe and efficient use of
the navigable airspace under instrument
conditions in the affected areas.
EFFECTIVE DATE: 0901 UTC, December
22, 2005.

telephone: (405) 954–4164.
SUPPLEMENTARY INFORMATION: This
amendment to part 95 of the Federal
Aviation Regulations (14 CFR part 95)
amends, suspends, or revokes IFR
altitudes governing the operation of all
aircraft in flight over a specified route
or any portion of that route, as well as
the changeover points (COPs) for
Federal airways, jet routes, or direct
routes as prescribed in part 95.
The Rule
The specified IFR altitudes, when
used in conjunction with the prescribed
changeover points for those routes,
ensure navigation aid coverage that is
adequate for safe flight operations and
free of frequency interference. The
reasons and circumstances that create
the need for this amendment involve
matters of flight safety and operational
efficiency in the National Airspace
System, are related to published
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
aeronautical charts that are essential to
the user, and provide for the safe and
efficient use of the navigable airspace.
In addition, those various reasons or
circumstances require making this
amendment effective before the next
scheduled charting and publication date
of the flight information to assure its
timely availability to the user. The
effective date of this amendment reflects
those considerations. In view of the
close and immediate relationship
between these regulatory changes and
safety in air commerce, I find that notice
and public procedure before adopting
this amendment are impracticable and
contrary to the public interest and that
good cause exists for making the
amendment effective in less than 30
days.
Conclusion
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current. It, therefore (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)
does not warrant preparation of a
regulatory evaluation as the anticipated
impact is so minimal. For the same
reason, the FAA certifies that this
amendment will not have a significant
economic impact on a substantial
number of small entities under the
criteria of the Regulatory Flexibility Act.

Operating in the restricted rpm range during ground operation can
excite a natural propeller blade frequency that creates damaging stress

cracks, leading to propeller structural failure.
Additionally, some operators use a water-methanol assist system to

operating procedures for the water-methanol assist system define an
airplane brakes-locked condition. Testing has shown that using the
water-methanol assist system with airplane brakes locked creates
propeller loadings exceeding structural fatigue limits of the propeller
hub. This condition, if not corrected, could result in cracked hubs,
which could cause failure of the propeller hub, blade separation, and
loss of control of the airplane.
Relevant Service Information
We reviewed and approved the technical contents of McCauley Alert

FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this AD, we found that notice and opportunity for public
comment before issuing this AD are impracticable. 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 send us any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. FAA-2005-22690;
Directorate Identifier 2005-NE-35-AD'' in the subject line of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it.
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 with FAA
personnel concerning this AD. Using the search function of the DMS Web
site, anyone can find and read the comments in any of our dockets. This
includes 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) or you may visit

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 Docket Offices 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.
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 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 at the
address listed under ADDRESSES.
