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 Fmt 4700 Sfmt 4700 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 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 http:// 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.

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.

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. FOR FURTHER INFORMATION CONTACT: Donald P. Pate, Flight Procedure Standards Branch (AMCAFS–420), Flight Technologies and Programs Division, Flight Standards Service, Federal Aviation Administration, Mike Monroney Aeronautical Center, 6500 South MacArthur Blvd. Oklahoma City, OK 73169 (Mail Address: P.O. Box 25082 Oklahoma City, OK 73125) 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.

Airworthiness Directives; McCauley Propeller Systems Five-Blade 
Propeller Assemblies

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

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 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 water-methanol 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,

[[Page 71757]]

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

    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 http://
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

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

directive:

2005-24-08 McCauley Propeller Systems: Amendment 39-14388. Docket 
No. FAA-2005-22690; Directorate Identifier 2005-NE-35-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December 
15, 2005.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to McCauley Propeller Systems propeller 
assemblies, part numbers (P/Ns) B5JFR36C1101/114GCA-0, C5JFR36C1102/
L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0. These 
propeller assemblies are installed on BAE Systems (Operations) 
Limited Jetstream Model 4100 series airplanes.

Unsafe Condition

    (d) 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.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified unless the 
actions have already been done.

Propeller Hub Reduced Life Limits

    (f) Remove any propeller hub from service that is currently, or 
ever was, operated on an engine with a water-methanol assist system, 
not later than 6,000 hours time-in-service (TIS).
    (g) Remove any other propeller hub from service not later than 
18,000 hours TIS.
    (h) Remove 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.

Prohibition of Hubs Exceeding Life Limit

    (i) Any propeller hub removed from service after exceeding its 
life limit must not be returned to service on any installation.

Propeller Hub Initial Inspection

    (j) For all installed propeller hubs, perform an eddy current 
inspection (ECI) within 200 hours TIS or 60 days after the effective 
date of this AD, whichever occurs first. Use the Accomplishment 
Instructions of McCauley Alert Service Bulletin (ASB) No. ASB250, 
dated September 12, 2005, to do the inspection.

Propeller Hub Repetitive Inspections

    (k) Thereafter, for all installed propeller hubs with 12,000 or 
more hours TIS:
    (1) Perform repetitive ECIs within 1,800 hours TIS or 12 months, 
whichever occurs first.
    (2) Use the Accomplishment Instructions of McCauley ASB No. 
ASB250, dated September 12, 2005, to do the inspections.

[[Page 71758]]

    (l) 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, due to the 6,000 hours 
TIS hub reduced life limit.
