Download as PDF nlaroche on DSK30NT082PROD with PROPOSALS 18722 Federal Register / Vol. 82, No. 76 / Friday, April 21, 2017 / Proposed Rules proposed California FMMO. Upon issuance of a Final Decision, producers and/or cooperative associations potentially affected by the proposed California FMMO would be authorized to vote in the referendum regarding their support of the Final Decision. Under this referendum, cooperative associations would be able to elect to bloc vote on behalf of their members; in this case, cooperative associations would submit to AMS a Cooperative Ballot in addition to a Certificate of Resolution and an Intent to Bloc Vote indicating the cooperative association’s decision to vote on behalf of its members. Cooperative associations that either check ‘‘no’’ or who do not return their Intent to Bloc Vote form to AMS promptly would be designated as not bloc voting on behalf of their members. In this case, a Milk Producer’s Ballot would be sent to each producer associated with that cooperative. Producers who are not associated with a cooperative would be sent a Milk Producer’s Ballot to indicate their support for or against the promulgation of the proposed California FMMO. These same ballots will be used by USDA to carry out future referendum procedures to determine support for promulgation or amendatory proceedings in other FMMO rulemakings. Estimate of Burden: Public reporting burden for this collection of information is estimated to average 0.25 hours per response. Respondents: Milk producers and cooperative associations. Estimated Number of Respondents: 1,443. Estimated Total Annual Responses: 1,453. Estimated Number of Responses per Respondent: 1. Estimated Total Annual Burden on Respondents: 363.25. As with all FMMOs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry. USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this document. USDA has performed this initial RFA analysis regarding the impact of this document on small businesses. An estimated 1,453 responses would provide information to AMS. The estimated cost of providing the information to AMS by respondents would be $12,205.20. This total has been estimated by multiplying 363.25 total hours required for reporting and recordkeeping by $33.60, the average mean hourly earnings of Farmers, Ranchers, and Other Agricultural VerDate Sep<11>2014 13:52 Apr 20, 2017 Jkt 241001 Managers, as denoted by the U.S. Department of Labor Statistics National Compensation Survey. The proposed California FMMO’s referendum procedures have been carefully reviewed, and every effort has been made to minimize any unnecessary recordkeeping costs or requirements, including efforts to utilize procedures already administered by USDA. Request for Public Comment Under the Paperwork Reduction Act Comments are invited on: (1) The accuracy of the agency’s estimate of the burden of the proposed collection of information including the validity of the methodology and assumptions used; (2) ways to enhance the quality, utility, and clarity of the information to be collected; and (3) ways to minimize the burden of the collection of information on those who are to respond, including the use of appropriate automated, electronic, mechanical, or other technological collection techniques or other forms of information technology. Comments concerning the information collection requirements contained in this action should reference OMB No. 0581–NEW. In addition, the docket number, date, and page number of this issue of the Federal Register also should be referenced. Comments should be sent to the same addresses referenced in the ADDRESSES section of this document. A 60-day comment period is provided to allow interested persons to comment on this proposed information collection. All written comments received will be summarized and included in the request for OMB approval. All comments will also become a matter of public record. Dated: April 17, 2017.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion nlaroche on DSK30NT082PROD with PROPOSALS The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2016– 0259, dated December 21, 2016 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During service and annual inspection, DG found that some fuel hoses with textile fabric covering, installed from the beginning of the year 2015, had become weak or untight with time. The suspected root cause for this premature degradation is a manufacturing defect of a certain batch of fuel hoses. This condition, if not detected and corrected, may lead to kinking of the fuel hoses, possibly resulting in a reduced fuel supply and consequent partial or total loss of available power. To address this unsafe condition, DGFlugzeugbau published Technical Note TN 800–44, 500–10, DG–SS–02 providing inspection and replacement instructions. For the reason described above, this AD requires inspection and replacement of the affected fuel hoses. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2017–0343. VerDate Sep<11>2014 13:52 Apr 20, 2017 Jkt 241001 Related Service Information Under 1 CFR Part 51 DG Flugzeugbau GmbH has issued Technical note No. 800–44, 500–10, DG–SS–02, are all dated November 9, 2016, and co-published as one document. The service information describes procedures for inspecting and replacing the fuel hoses. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM. 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. Costs of Compliance We estimate that this proposed AD will affect 59 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with each inspection required by this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the inspection cost of this proposed AD on U.S. operators to be $10,030, or $170 per product. In addition, we estimate that each replacement action required by this proposed AD would take about 8 workhours and require parts costing $500. Based on these figures, we estimate the replacement cost of this proposed AD on U.S. operators to be $69,620, or $1,180 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 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 18723 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2016-0259, dated December 21, 2016 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During service and annual inspection, DG found that some fuel 
hoses with textile fabric covering, installed from the beginning of 
the year 2015, had become weak or untight with time. The suspected 
root cause for this premature degradation is a manufacturing defect 
of a certain batch of fuel hoses.
    This condition, if not detected and corrected, may lead to 
kinking of the fuel hoses, possibly resulting in a reduced fuel 
supply and consequent partial or total loss of available power.
    To address this unsafe condition, DG-Flugzeugbau published 
Technical Note TN 800-44, 500-10, DG-SS-02 providing inspection and 
replacement instructions.
    For the reason described above, this AD requires inspection and 
replacement of the affected fuel hoses.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0343.

Related Service Information Under 1 CFR Part 51

    DG Flugzeugbau GmbH has issued Technical note No. 800-44, 500-10, 
DG-SS-02, are all dated November 9, 2016, and co-published as one 
document. The service information describes procedures for inspecting 
and replacing the fuel hoses. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section of this NPRM.

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.

Costs of Compliance

    We estimate that this proposed AD will affect 59 products of U.S. 
registry. We also estimate that it would take about 2 work-hours per 
product to comply with each inspection required by this proposed AD. 
The average labor rate is $85 per work-hour.
    Based on these figures, we estimate the inspection cost of this 
proposed AD on U.S. operators to be $10,030, or $170 per product.
    In addition, we estimate that each replacement action required by 
this proposed AD would take about 8 work-hours and require parts 
costing $500. Based on these figures, we estimate the replacement cost 
of this proposed AD on U.S. operators to be $69,620, or $1,180 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 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

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by adding the following new AD:

DG Flugzeugbau GmbH: Docket No. FAA-2017-0343; Directorate 
Identifier 2017-CE-005-AD.

(a) Comments Due Date

    We must receive comments by June 5, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to certain DG Flugzeugbau GmbH Models DG-400, 
DG-500M, DG-

[[Page 18724]]

500MB, DG-800A, and DG-800B gliders, all serial numbers, that:
    (1) Have textile fabric covered fuel hoses installed in the 
fuselage; and
    (2) are certificated in any category.

    Note 1 to paragraph (c) of this AD: Metal fabric covered fuel 
hoses installed in the engine area are not affected by this AD.

(d) Subject

    Air Transport Association of America (ATA) Code 28: Fuel.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated 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 a manufacturing 
defect in certain textile fabric covered fuel hoses, which could 
cause the fuel hose to fail. We are issuing this AD to prevent 
failure of the fuel hose, which could cause reduced fuel supply and 
result in partial or total loss of power.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Within the next 30 days after the effective date of this AD, 
inspect all textile fabric covered fuel hoses located in the 
fuselage following Instructions 1. of DG Flugzeugbau GmbH Technical 
note (TN) No. 800-44, 500-10, DG-SS-02, dated November 9, 2016.

    Note 2 to paragraph (f)(1) through (6) of this AD: DG 
Flugzeugbau GmbH Technical note (TN) No. 800-44, DG Flugzeugbau GmbH 
Technical note (TN) No. 500-10, and DG Flugzeugbau GmbH Technical 
note (TN) No. DG-SS-02 are all dated November 9, 2016, and co-
published as one document.

    (2) If any kinking or wet fabric covering is found during the 
inspection required in paragraph (f)(1) of this AD, within the next 
14 days after the inspection, replace all textile fabric covered 
fuel hoses located in the fuselage following Instructions 2. of DG 
Flugzeugbau GmbH TN No. 800-44, 500-10, DG-SS-02, dated November 9, 
2016.
    (3) If no kinking or wet fabric covering is found during the 
inspection required in paragraph (f)(1) of this AD, within the next 
12 months after the effective date of this AD, replace all textile 
fabric covered fuel hoses located in the fuselage following 
Instructions 2. of DG Flugzeugbau GmbH TN No. 800-44, 500-10, DG-SS-
02, dated November 9, 2016.
    (4) Within 12 months after doing the replacements required in 
paragraph (f)(2) or (f)(3) of this AD, as applicable, and 
repetitively thereafter at intervals not to exceed 12 months, 
inspect all fuel hoses in the fuselage for any signs of wear, 
fissures, kinks, lack of tight fit, or leaks. For this inspection, 
the ignition switch must be turned on to run the electric fuel pump 
to demonstrate an operating fuel pressure, as specified in 
Instructions 4. of DG Flugzeugbau GmbH TN No. 800-44, 500-10, DG-SS-
02, dated November 9, 2016.
    (5) If any signs of wear, fissures, kinks, lack of tight fit, or 
leaks are found during any inspection required in paragraph (f)(4) 
of this AD, replace the defective fuel hose in the fuselage 
following Instructions 2. of DG Flugzeugbau GmbH TN No. 800-44, 500-
10, DG-SS-02, dated November 9, 2016. Continue with the repetitive 
inspections as specified in paragraph (f)(4) of this AD.
    (6) If no signs of wear, fissures, kinks, lack of tight fit, or 
leaks are found during any inspection required in paragraph (f)(4) 
of this AD, at intervals not to exceed 10 years, replace the fuel 
hoses in the fuselage with new fuel hoses following Instructions 2. 
of DG Flugzeugbau GmbH TN No. 800-44, 500-10, DG-SS-02, dated 
November 9, 2016.
