ACTION: Final rule; correcting amendments. AGENCY: The Department of Energy (DOE) corrects two errors in its Occupational Radiation Protection regulations. One error originated in a final rulemaking (FR Doc. 98–27366), which was published in the Federal Register of Wednesday, November 4, 1998 (63 FR 59661). The second error originated in a final rulemaking (FR Doc. E7–10477), which was published in the Federal Register of Friday, June 8, 2007 (72 FR 31903). DATES: Effective Date: April 21, 2009. FOR FURTHER INFORMATION CONTACT: Judith Foulke, (301) 903–5865, e-mail: Judy.Foulke@hq.doe.gov. SUMMARY: mstockstill on PROD1PC66 with RULES Background DOE first published title 10, Code of Federal Regulations, part 835, Occupational Radiation Protection (part 835), as a final rule on December 14, 1993. In the November 4, 1998, amendment to part 835, DOE, in part, revised footnote 1 to appendix D. The revised footnote references an exception noted in footnote 5. The exception is actually found in footnote 6. When DOE proposed amending part 835 on August 10, 2006, DOE proposed correcting this error; however, in the final rule amending part 835 on June 8, 2007, the correction was not made. Accordingly, footnote 1 needs to be revised to reference the exception in footnote 6. When DOE proposed amending part 835 on August 10, 2006, DOE proposed revising the definition of ‘‘absorbed 17:57 Apr 20, 2009 Jkt 217001 1 The values in this appendix, with the exception noted in footnote 6 below, apply to radioactive contamination deposited on, but not incorporated into the interior or matrix of, the contaminated item. Where surface contamination by both alpha- and beta-gamma-emitting nuclides exists, the limits established for alpha- and beta-gammaemitting nuclides apply independently. 14 CFR Part 39 List of Subjects in 10 CFR Part 835 Federal buildings and facilities, Nuclear energy, Nuclear materials, Nuclear power plants and reactors, Nuclear safety, Occupational safety and health, Radiation protection, and Reporting and recordkeeping requirements. ■ Accordingly, 10 CFR part 835 is corrected by making the following correcting amendments: PART 835—OCCUPATIONAL RADIATION PROTECTION 1. The authority citation for part 835 continues to read as follows: ■ Authority: 42 U.S.C. 2201, 7191; 50 U.S.C. 2410. SUPPLEMENTARY INFORMATION: VerDate Nov<24>2008 dose’’ to read: ‘‘Absorbed dose (D) means the average energy absorbed by matter from ionizing radiation per unit mass of irradiated material. The absorbed dose is expressed in units of rad (or gray) (1 rad = 0.01 gray).’’ During the public comment period, a comment was received that the definition should be changed from ‘‘energy absorbed by matter’’ to ‘‘energy imparted.’’ As noted in the preamble to the June 8, 2007, amendment, DOE agreed with the comment and revised the definition to read: ‘‘Absorbed dose (D) means the average energy imparted by ionizing radiation to the matter in a volume element. The absorbed dose is expressed in units of rad (or gray) (1 rad = 0.01 gray).’’ In making this revision, the phrase ‘‘per unit mass of irradiated material’’ was inadvertently deleted from the end of the first sentence. Need for Corrections This correction revises the definition of ‘‘absorbed dose’’ and changes the reference to footnote 6 in footnote 1 of appendix D to part 835. 2. Section 145.14 is amended by revising the section heading to read as follows: ■ 2.

Models PC–12 and PC–12/45 Airplanes AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. 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: This Airworthiness Directive (AD) is prompted by some occurrences where the Deice Pressure Regulator has vented too much hot air into the forward compartment damaging the oxygen cylinder ON/OFF cable, the Ram-Air Scoop cable and the Environmental Control System (ECS) firewall shut-off valve cable. If incorrectly adjusted, or defective, the Deice Pressure Regulator can vent hot air into the forward compartment. This situation can cause overheating and failures of components located inside the forward compartment, which could result in potential loss of several functions essential for safe flight. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective May 26, 2009. On May 26, 2009, the Director of the Federal Register approved the E:\FR\FM\21APR1.SGM 21APR1 Federal Register / Vol. 74, No. 75 / Tuesday, April 21, 2009 / Rules and Regulations incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on February 13, 2009 (74 FR 7198). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: This Airworthiness Directive (AD) is prompted by some occurrences where the Deice Pressure Regulator has vented too much hot air into the forward compartment damaging the oxygen cylinder ON/OFF cable, the Ram-Air Scoop cable and the Environmental Control System (ECS) firewall shut-off valve cable. If incorrectly adjusted, or defective, the Deice Pressure Regulator can vent hot air into the forward compartment. This situation can cause overheating and failures of components located inside the forward compartment, which could result in potential loss of several functions essential for safe flight. For the reason described above, this AD mandates the installation of a flange and scoop in the aircraft skin to vent the hot air from the Deice Pressure Regulator overboard. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. mstockstill on PROD1PC66 with RULES Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use VerDate Nov<24>2008 17:57 Apr 20, 2009 Jkt 217001 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 and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD. Costs of Compliance We estimate that this AD will affect 131 products of U.S. registry. We also estimate that it will take about 2 workhours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $1,000 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD on U.S. operators to be $151,960, or $1,160 per product. 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. PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 18117 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 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.

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:

    This Airworthiness Directive (AD) is prompted by some 
occurrences where the Deice Pressure Regulator has vented too much 
hot air into the forward compartment damaging the oxygen cylinder 
ON/OFF cable, the Ram-Air Scoop cable and the Environmental Control 
System (ECS) firewall shut-off valve cable.
    If incorrectly adjusted, or defective, the Deice Pressure 
Regulator can vent hot air into the forward compartment. This 
situation can cause overheating and failures of components located 
inside the forward compartment, which could result in potential loss 
of several functions essential for safe flight.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on February 13, 2009 
(74 FR 7198). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    This Airworthiness Directive (AD) is prompted by some 
occurrences where the Deice Pressure Regulator has vented too much 
hot air into the forward compartment damaging the oxygen cylinder 
ON/OFF cable, the Ram-Air Scoop cable and the Environmental Control 
System (ECS) firewall shut-off valve cable.
    If incorrectly adjusted, or defective, the Deice Pressure 
Regulator can vent hot air into the forward compartment. This 
situation can cause overheating and failures of components located 
inside the forward compartment, which could result in potential loss 
of several functions essential for safe flight.
    For the reason described above, this AD mandates the 
installation of a flange and scoop in the aircraft skin to vent the 
hot air from the Deice Pressure Regulator overboard.

You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might 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 and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 131 products of U.S. registry. 
We also estimate that it will take about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $80 per work-hour. Required parts will cost about $1,000 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these costs. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $151,960, or $1,160 per product.

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 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES

ON/OFF cable, the Ram-Air Scoop cable and the Environmental Control 
System (ECS) firewall shut-off valve cable.
    If incorrectly adjusted, or defective, the Deice Pressure 
Regulator can vent hot air into the forward compartment. This 
situation can cause overheating and failures of components located 
inside the forward compartment, which could result in potential loss 
of several functions essential for safe flight.
    For the reason described above, this AD mandates the 
installation of a flange and scoop in the aircraft skin to vent the 
hot air from the Deice Pressure Regulator overboard.

Actions and Compliance

    (f) Unless already done, within the next 3 months after May 26, 
2009 (the effective date of this AD), install an overboard vent for 
the airfoil deice system pressure regulator (Modification Kit Number 
500.50.12.332) following the Accomplishment Instructions in PILATUS 
AIRCRAFT LTD. PC12 Service Bulletin No. 30-011, dated July 9, 2008.
