(b) Places of production requirements. (1) Registered places of production of tree tomatoes destined for export to the continental United States must be determined by APHIS and the NPPO of Ecuador to be free from A. fraterculus and C. capitata based on trapping conducted in accordance with the operational workplan. If the flies per trap per day exceed levels specified in the operational workplan, the place of production will be prohibited from exporting tree tomatoes to the continental United States until APHIS and the NPPO of Ecuador jointly agree that the risk has been mitigated. The NPPO must keep records regarding the placement and monitoring of all traps, as well as records of all pest detections in these traps, for at least 1 year and provide the records to APHIS, upon request. (2) Places of production must remove fallen tree tomato fruit in accordance with the operational workplan. Fallen fruit may not be included in field containers of fruit brought to the packinghouse to be packed for export. (3) The NPPO of Ecuador must inspect fields at registered places of production at least once during the growing season for Tamarillo mosaic virus. Sites must be determined by the NPPO to be free of the virus as a result of these inspections. (4) Starting 60 days before harvest and continuing throughout the shipping season, the NPPO of Ecuador must visit and inspect registered places of production monthly for signs of infestation. The NPPO of Ecuador must allow APHIS to monitor these inspections. The NPPO of Ecuador must also certify to APHIS that registered places of production have effective fruit fly trapping programs and control guidelines in place to reduce pest populations. (5) If APHIS or the NPPO of Ecuador determines that a registered place of production has failed to follow the requirements in this paragraph (b), the place of production will be excluded from the export program until APHIS and the NPPO of Ecuador jointly agree that the place of production has taken appropriate remedial measures to address the plant pest risk. (c) Packinghouse requirements. (1) During the time registered packinghouses are in use for packing VerDate Sep<11>2014 17:44 Jun 20, 2017 Jkt 241001 tree tomatoes for export to the continental United States, the packinghouse can only accept tree tomatoes that are from registered places of production and that are produced in accordance with this section. (2) Tree tomatoes must be packed in insect-proof cartons or containers, or covered with insect-proof mesh or plastic tarpaulin, within 24 hours of harvest. These safeguards must remain intact until the tree tomatoes arrive in the United States, or the consignment will not be allowed to enter the United States. (3) All openings to the outside of the packinghouse must be covered by screening with openings of not more than 1.6 mm or by some other barrier that prevents pests from entering. The packinghouse must have double doors at the entrance to the facility and at the interior entrance to the area where the tree tomatoes are packed. (d) Phytosanitary inspections. A biometric sample of tree tomato fruit jointly agreed upon by the NPPO of Ecuador and APHIS must be inspected in Ecuador by the NPPO of Ecuador or officials authorized by the NPPO of Ecuador following post-harvest processing. The sample must be visually inspected for N. elegantalis and Tamarillo mosaic virus. A portion of the fruit must then be cut open and inspected for A. fraterculus and C. capitata. (1) If N. elegantalis is found, the entire lot of fruit will be prohibited from import into the United States unless it is treated with an approved quarantine treatment monitored by APHIS. (2) If Tamarillo mosaic virus is found, the entire lot of fruit will be prohibited from importation into the United States. (3) If a single larva of A. fraterculus or C. capitata is found, the entire lot of fruit will be prohibited from importation to the United States and the place of production producing that fruit will be suspended from the export program until appropriate measures, as agreed upon by the NPPO of Ecuador and APHIS, have been taken. (e) Phytosanitary certificate. Each consignment of fresh tree tomato fruit from Ecuador must be accompanied by a phytosanitary certificate, issued by the NPPO of Ecuador, that contains an additional declaration that the tomatoes were produced in accordance with the requirements of this section, and have been inspected and found free of A. fraterculus, C. capitata, N. elegantalis, and the Tamarillo mosaic virus.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2016–22, dated June 24, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL– 600–2C10 (Regional Jet Series 700, 701, & 702), Model CL–600–2D15 (Regional Jet Series 705), Model CL–600–2D24 (Regional Jet Series 900), and Model CL–600–2E25 (Regional Jet Series 1000) airplanes. The MCAI states: An inspection by the vendor revealed that a number of Rubber Bull Gear (RBG) Wheels installed in the Horizontal Stabilizer Trim Actuator (HSTA) of the CL–600–2C10, CL– 600–2D15, CL–600–2D24 and CL–600–2E25 aeroplanes were manufactured from the incorrect material specification. The use of the incorrect material specification has a direct impact on the RBG Wheels life limit. The teeth of these non-conforming RBG Wheels may experience premature wear out and if not corrected, this condition could result in difficulties in maneuvering the aeroplane. This [Canadian] AD mandates replacement of the RBGs whose wheels have been made using an incorrect material specification. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0562. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 670BA–27–072, Revision A, dated October 26, 2016. This service information describes procedures for identification of affected HSTAs, and replacement if necessary. 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. 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 these same type designs. Costs of Compliance We estimate that this proposed AD affects 544 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Inspection and Replacement ...... Up to 20 work-hours × $85 per hour = $1700 ............. asabaliauskas on DSKBBXCHB2PROD with PROPOSALS 1 We Cost per product Parts cost (1) Cost on U.S. operators Up to $1700 ...... Up to $924,800. have received no definitive data that would enable us to provide cost estimates for the parts cost specified in this proposed AD. According to the manufacturer, some of the costs of this proposed 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, VerDate Sep<11>2014 17:44 Jun 20, 2017 Jkt 241001 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 PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 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 E:\FR\FM\21JNP1.SGM 21JNP1 28268 Federal Register / Vol. 82, No. 118 / Wednesday, June 21, 2017 / Proposed Rules 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

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-22, dated June 24, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc., Model CL-600-2C10 
(Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet 
Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-
600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

    An inspection by the vendor revealed that a number of Rubber 
Bull Gear (RBG) Wheels installed in the Horizontal Stabilizer Trim 
Actuator (HSTA) of the CL-600-2C10, CL-600-2D15, CL-600-2D24 and CL-
600-2E25 aeroplanes were manufactured from the incorrect material 
specification. The use of the incorrect material specification has a 
direct impact on the RBG Wheels life limit. The teeth of these non-
conforming RBG Wheels may experience premature wear out and if not 
corrected, this condition could result in difficulties in 
maneuvering the aeroplane.
    This [Canadian] AD mandates replacement of the RBGs whose wheels 
have been made using an incorrect material specification.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0562.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 670BA-27-072, Revision A, 
dated October 26, 2016. This service information describes procedures 
for identification of affected HSTAs, and replacement if necessary. 
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.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 544 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                Cost on  U.S.
            Action                   Labor cost         Parts cost      Cost per product          operators
----------------------------------------------------------------------------------------------------------------
Inspection and Replacement...  Up to 20 work-hours x           (\1\)  Up to $1700.........  Up to $924,800.
                                $85 per hour = $1700.
----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that would enable us to provide cost estimates for the parts cost
  specified in this proposed AD.

    According to the manufacturer, some of the costs of this proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a

[[Page 28268]]

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

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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2017-0562; Directorate Identifier 
2017-NM-027-AD.

(a) Comments Due Date

    We must receive comments by August 7, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Bombardier, Inc., airplanes identified in 
paragraphs (c)(1) through (c)(4) of this AD, certificated in any 
category, equipped with horizontal stabilizer trim actuator (HSTA) 
part number 8489-7 or 8489-7R.
    (1) Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) 
airplanes.

incorrect material specification. We are issuing this AD to prevent 
premature wear-out of the teeth of the RBG wheels, which could cause 
difficulties in maneuvering the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Serial Number Verification

    Within 600 flight hours after the effective date of this AD, 
inspect to determine whether the serial number (S/N) of the 
installed HSTA is listed in paragraph 1.A, ``Effectivity,'' of 
Bombardier Service Bulletin 670BA-27-072, Revision A, dated October 
26, 2016. If the S/N of the installed HSTA is not listed in 
paragraph 1.A, ``Effectivity,'' of Bombardier Service Bulletin 
670BA-27-072, Revision A, dated October 26, 2016, no further action 
is required by this AD, except as required by paragraph (j) of this 
AD. A review of airplane maintenance records is acceptable in lieu 
of this inspection if the part number of the HSTA can be 
conclusively determined from that review.

(h) Replacement
