Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC–8–102, –103, –106, –201, –202, –301, –311, and –315 series airplanes. This proposed AD was prompted by a report of a pilot commanding an in-flight engine shut down in response to a low oil pressure warning indication. Further investigation revealed the mounting studs in the engine mounted alternating current (AC) generator mounting plate were pulled out of position and the threaded interface in the plate was corroded. This proposed AD would require repetitive inspections for SUMMARY: PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 discrepancies on certain AC generator mounting adapters, and replacing discrepant adapters with serviceable ones. This proposed AD would also require revising the maintenance program to incorporate a repetitive task specified in certain temporary revisions. We are proposing this AD to detect and correct corrosion in the AC generator mounting plate, which could result in a gap between the AC generator and the generator mounting plate, and cause loss of engine oil and consequent engine failure.

Discussion wreier-aviles on DSK5TPTVN1PROD with PROPOSALS Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive, CF–2012–29, dated November 22, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: An incident has been reported on the DHC–8 aeroplane of a pilot commanded inflight engine shut down in response to a[n] engine low oil pressure warning indication. Further investigation revealed the mounting studs in the engine mounted AC generator mounting plate were pulled out of position and the threaded interface in the plate corroded. This resulted in a gap between the AC generator and the generator mounting plate, leading to the loss of engine oil and the ensuing illumination of the associated engine low oil pressure warning indication. To ensure the integrity of the affected units, Part I of this [TCCA] AD mandates an [general visual and mechanical] inspection of the affected AC generator mounting adapters part numbers (P/N) 31708–500 or 31708–501, and, as applicable, replacement with new or serviceable mounting plates. Part II of this [TCCA] AD mandates the incorporation of a repeat Maintenance Review Board (MRB) inspection applicable to the replacement of the AC generator mounting adapters P/Ns 31708–510 or 31708–511 only. You may obtain further information by examining the MCAI in the AD docket. VerDate Mar<15>2010 14:58 Aug 27, 2013 Jkt 229001 Relevant Service Information Bombardier has issued the following service information: • Bombardier Service Bulletin 8–24– 88, dated December 13, 2011. • de Havilland Dash 8 Series 100 Temporary Revision MRB–153, dated July 10, 2012, Part 1 Section 2–Systems, of the de Havilland Dash 8 Series 100 Maintenance Program Manual PSM 1– 8–7 MRB Report. • de Havilland Dash 8 Series 200 Temporary Revision MRB 2–31, dated July 10, 2012, Part 1 Section 2–Systems of the de Havilland Dash 8 Series 200 Maintenance Program Manual PSM 1– 82–7 MRB Report. • de Havilland Dash 8 Series 300 Temporary Revision MRB 3–162, dated July 10, 2012, Part 1 Section 2–Systems of the de Havilland Dash 8 Series 300 Maintenance Program Manual PSM 1– 83–7 MRB Report. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these actions, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (j)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 88 products of U.S. registry. PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 53081 We also estimate that it would take about 5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $4,000 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 parts. 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 the proposed AD on U.S. operators to be $389,400, or $4,425 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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, 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed 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); 3. Will not affect intrastate aviation in Alaska; and 4. Will not have a significant economic impact, positive or negative, E:\FR\FM\28AUP1.SGM 28AUP1 53082 Federal Register / Vol. 78, No. 167 / Wednesday, August 28, 2013 / Proposed Rules 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 proposed AD and placed it in the AD docket.

Executive Summary of Rule This rule updates the oil and gas regulations governing Osage County. It is intended to strengthen the management and administration of the Osage mineral estate for the benefit of the Osage. These provisions provide updated reporting and inspection requirements, further specify lessee obligations with respect to operations, revise royalty rate calculations and update the amounts for bonds, fines and penalties. II. Background On October 14, 2011, the United States and the Osage Nation (formerly known as the Osage Tribe) signed a Settlement Agreement to resolve litigation regarding alleged mismanagement of the Osage Nation’s oil and gas mineral estate, among other claims. In the Settlement Agreement, the parties agreed that it would be mutually beneficial ‘‘to address means of improving the trust management of the Osage Mineral Estate, the Osage Tribal Trust Account, and Other Osage Accounts.’’ The parties agreed that a review and revision of the existing regulations is warranted to better assist the Bureau of Indian Affairs (BIA) in managing the Osage Mineral Estate. The parties agreed to engage in a negotiated rulemaking for this purpose. For additional information on the negotiated rulemaking, please visit https:// www.bia.gov/osageregneg/. The Committee submitted its report to BIA on April 25, 2013. BIA has based this proposed rule on the report. III. Detailed Explanation of Revisions This rule revises 25 CFR part 226 by changing all references to the ‘‘Osage Tribal Council’’ to the ‘‘Osage Minerals Council’’ because the Osage Tribal Council no longer exists and the Osage Minerals Council has the authority to make decisions regarding the Osage minerals estate.

RIN 2120-AA64


Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, 
-311, and -315 series airplanes. This proposed AD was prompted by a 
report of a pilot commanding an in-flight engine shut down in response 
to a low oil pressure warning indication. Further investigation 
revealed the mounting studs in the engine mounted alternating current 
(AC) generator mounting plate were pulled out of position and the 
threaded interface in the plate was corroded. This proposed AD would 
require repetitive inspections for discrepancies on certain AC 
generator mounting adapters, and replacing discrepant adapters with 
serviceable ones. This proposed AD would also require revising the 
maintenance program to incorporate a repetitive task specified in 
certain temporary revisions. We are proposing this AD to detect and 
correct corrosion in the AC generator mounting plate, which could 
result in a gap between the AC generator and the generator mounting 
plate, and cause loss of engine oil and consequent engine failure.

DATES: We must receive comments on this proposed AD by October 15, 2013

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive, CF-
2012-29, dated November 22, 2012 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    An incident has been reported on the DHC-8 aeroplane of a pilot 
commanded in-flight engine shut down in response to a[n] engine low 
oil pressure warning indication.
    Further investigation revealed the mounting studs in the engine 
mounted AC generator mounting plate were pulled out of position and 
the threaded interface in the plate corroded. This resulted in a gap 
between the AC generator and the generator mounting plate, leading 
to the loss of engine oil and the ensuing illumination of the 
associated engine low oil pressure warning indication.
    To ensure the integrity of the affected units, Part I of this 
[TCCA] AD mandates an [general visual and mechanical] inspection of 
the affected AC generator mounting adapters part numbers (P/N) 
31708-500 or 31708-501, and, as applicable, replacement with new or 
serviceable mounting plates.
    Part II of this [TCCA] AD mandates the incorporation of a repeat 
Maintenance Review Board (MRB) inspection applicable to the 
replacement of the AC generator mounting adapters P/Ns 31708-510 or 
31708-511 only.

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

Relevant Service Information

    Bombardier has issued the following service information:
     Bombardier Service Bulletin 8-24-88, dated December 13, 
2011.
     de Havilland Dash 8 Series 100 Temporary Revision MRB-153, 
dated July 10, 2012, Part 1 Section 2-Systems, of the de Havilland Dash 
8 Series 100 Maintenance Program Manual PSM 1-8-7 MRB Report.
     de Havilland Dash 8 Series 200 Temporary Revision MRB 2-
31, dated July 10, 2012, Part 1 Section 2-Systems of the de Havilland 
Dash 8 Series 200 Maintenance Program Manual PSM 1-82-7 MRB Report.
     de Havilland Dash 8 Series 300 Temporary Revision MRB 3-
162, dated July 10, 2012, Part 1 Section 2-Systems of the de Havilland 
Dash 8 Series 300 Maintenance Program Manual PSM 1-83-7 MRB Report.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections). Compliance with 
these inspections is required by 14 CFR 91.403(c). For airplanes that 
have been previously modified, altered, or repaired in the areas 
addressed by these actions, the operator may not be able to accomplish 
the inspections described in the revisions. In this situation, to 
comply with 14 CFR 91.403(c), the operator must request approval for an 
alternative method of compliance according to paragraph (j)(1) of this 
AD. The request should include a description of changes to the required 
inspections that will ensure the continued operational safety of the 
airplane.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 88 products of U.S. registry. We also estimate that 
it would take about 5 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $4,000 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 
parts. 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 the proposed AD on U.S. operators to 
be $389,400, or $4,425 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
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, 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
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);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative,

[[Page 53082]]

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 proposed AD and placed it in the AD docket.
