Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2014– 0212, dated September 19, 2014 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for certain PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 Grob-Werke Models G115EG and G120A airplanes. The MCAI states: An operator of a G 115E aeroplane experienced a total loss of electrical power in flight. The root cause was found to be a defective starter solenoid causing an internal short circuit, which resulted in breakdown of the system voltage. This condition, if not detected and corrected, could result in reduced control of the aeroplane. To address this potential unsafe condition, GROB Aircraft AG issued Service Bulletin (SB) MSB1078–196 for G 115 aeroplanes and SB MSB1121–144 for G 120 aeroplanes to provide instructions for inspection and corrective action. For the reason described above, this AD requires a one-time inspection of the starter solenoid and, depending on the findings, replacement of the starter. A technical solution is currently under development and further AD action may follow. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2014–0848. Relevant Service Information GROB Aircraft has issued Service Bulletin No. MSB1078–196 and Service Bulletin No. MSB1121–144, both dated July 14, 2014. 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Interim Action We consider this proposed AD interim action. GROB Aircraft is currently working on a final technical solution to resolve the unsafe condition. If final action is later identified, we might consider further rulemaking. Costs of Compliance We estimate that this proposed AD will affect 6 products of U.S. registry. We also estimate that it would take about 4 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. E:\FR\FM\23OCP1.SGM 23OCP1 Federal Register / Vol. 79, No. 205 / Thursday, October 23, 2014 / Proposed Rules Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $2,040, or $340 per product. In addition, we estimate that any necessary follow-on actions would take about 4 work-hours and require parts costing $600, for a cost of $940 per product. We have no way of determining the number of products that may need these actions. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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. mstockstill on DSK4VPTVN1PROD with PROPOSALS 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2014-0212, dated September 19, 2014 (referred to after this as 
``the MCAI''), to correct an unsafe condition for certain Grob-Werke 
Models G115EG and G120A airplanes. The MCAI states:

    An operator of a G 115E aeroplane experienced a total loss of 
electrical power in flight. The root cause was found to be a 
defective starter solenoid causing an internal short circuit, which 
resulted in breakdown of the system voltage.
    This condition, if not detected and corrected, could result in 
reduced control of the aeroplane.
    To address this potential unsafe condition, GROB Aircraft AG 
issued Service Bulletin (SB) MSB1078-196 for G 115 aeroplanes and SB 
MSB1121-144 for G 120 aeroplanes to provide instructions for 
inspection and corrective action.
    For the reason described above, this AD requires a one-time 
inspection of the starter solenoid and, depending on the findings, 
replacement of the starter.
    A technical solution is currently under development and further 
AD action may follow.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2014-0848.

Relevant Service Information

    GROB Aircraft has issued Service Bulletin No. MSB1078-196 and 
Service Bulletin No. MSB1121-144, both dated July 14, 2014. 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Interim Action

    We consider this proposed AD interim action. GROB Aircraft is 
currently working on a final technical solution to resolve the unsafe 
condition. If final action is later identified, we might consider 
further rulemaking.

Costs of Compliance

    We estimate that this proposed AD will affect 6 products of U.S. 
registry. We also estimate that it would take about 4 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour.

[[Page 63341]]

    Based on these figures, we estimate the cost of this proposed AD on 
U.S. operators to be $2,040, or $340 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 4 work-hours and require parts costing $600, for a cost of 
$940 per product. We have no way of determining the number of products 
that may need these actions.

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.

any airplane to which the AMOC applies, notify your appropriate 
principal inspector (PI) in the FAA Flight Standards District Office 
(FSDO), or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
