Discussion

The Civil Aviation Safety Authority (CASA), which is the aviation authority for Australia, has issued AD No. AD/ GA8/7, dated September 2, 2013 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

The GippsAero GA8 and GA8–TC 320 aircraft Mk II fuel system features an integral sump tank located in the floor structure forward of the co-pilot seat. The current configuration of the compartments adjacent to the Mk II sump tank do not meet the requirements of regulation 23.967(b) of the Federal Aviation Regulations of the United States of America in that they are not suitably ventilated and drained to prevent the accumulation of flammable fluids or vapours.

This AD requires modifying the fuel system for ventilation and drainage. You may examine the MCAI on the Internet
at http://www.regulations.gov by searching for and locating it in Docket No. FAA–2013–0823.

Relevant Service Information

GippsAero has issued Mandatory Service Bulletin SB–GA8–2012–96, Issue 4, dated August 12, 2013. 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 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

FAA’s Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the integral sump tank in the fuel system is not suitably ventilated and drained to prevent the accumulation of flammable fluids or vapors, which could lead to a flammability issue. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include ‘‘Docket No. FAA–2013–0823; Directorate Identifier 2013–CE–027– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those
comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.


### 58873 Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Rules and Regulations

Costs of Compliance

We estimate that this AD will affect 35 products of U.S. registry. We alsoestimate that it will take about 3 workhours per product to do the fuel system ventilation and drainage modification requirement of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $8,925, or $255 per product.

In addition, we estimate that it will take about 4 work-hours per product to do the cargo pod modification. The average labor rate is $85 per work-hour. Required parts would cost about $1,000 per product, for a cost of $1,340 per product. We have no way of determining the number of products that may need this action.

According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 this AD:

(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. List of Subjects in 14 CFR Part 39

**Airworthiness Directives; PILATUS AIRCRAFT LTD. Airplanes** 

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

**ACTION :**  Final rule.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for PILATUS AIRCRAFT LTD. Model PC– 12/47E airplanes. 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 common grounding of both the pilot primary flight display (PFD) and the Electronic Standby Instrument System (ESIS). If the common ground fails both navigations systems could fail simultaneously, which could result in loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.

**DATES :**  This AD is effective October 30,
2013. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of October 30, 2013.

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 July 17, 2013 (78 FR 42723). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

During a design review of the electrical supply of navigation equipment installed on certain PC 12/47E aeroplanes, common grounding of the pilot Primary Flight Display (PFD) and the Electronic Standby Instrument System (ESIS) was identified.

This condition, if not corrected, could lead, in case of failure of PFD and ESIS common ground, to simultaneous loss of more than one pilot flight information display and inhibition of flight parameter presentation, possibly resulting in reduced ability to control the aeroplane.

To address this potentially unsafe condition, Pilatus Aircraft Ltd. introduced a modification in production to relocate the ESIS ground connection. This modification is available for affected in-service aeroplanes through Pilatus Aircraft Ltd Service Bulletin (SB) No 34–038. For the reasons described above, this AD requires relocation of the ESIS ground connection. The MCAI can be found in the AD docket on the Internet at http://www.regulations.gov/ #!documentDetail;D=FAA-2013-0610-
0002

. Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 42723, July 17, 2013) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (78 FR 42723, July 17, 2013) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 42723, July 17, 2013). Costs of Compliance

We estimate that this AD will affect 230 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 AD. The average labor rate is $85 per work-hour. Required parts would cost about $40 per product.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $106,950, or $465 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
