**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.

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 theDHC–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. 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,

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. List of Subjects in 14 CFR Part 39

**SUPPLEMENTARY INFORMATION :**  I. 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 http:// 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. To avoid confusion in terminology, this rule changes all
