SUPPLEMENTARY INFORMATION: On April 4, 2016, we published in the Federal Register (81 FR 19063, Docket No. APHIS–2015–0051) a proposal to the fruits and vegetables regulations to list lemon (Citrus limon (L.) Burm. f.) from Chile as eligible for importation into the continental United States subject to a systems approach. Our review of the information supporting the safe importation into the United States of citrus from Chile under the listed phytosanitary measures is examined in a commodity import evaluation document (CIED) titled ‘‘Importation of Fresh Lemons (Citrus limon (L.) Burm. F.), from Chile into the Continental United States Using a Systems Approach.’’ The CIED was based on a pathway-initiated risk assessment (PRA), titled ‘‘Importation of Fresh Lemons (Citrus limon (L.) Burm. f.) from Chile into the Continental United States.’’ The draft PRA was made available for review and comment on the APHIS Web page in 2014. However, we did not make the PRA available with the proposed rule for further review and comment. A commenter on the proposed rule asked that we make the PRA available again. In response to this comment we are making the PRA available for review and reopening the comment period. Copies of the CIED and PRA may be obtained from the person listed under FOR FURTHER INFORMATION CONTACT or viewed on the Regulations.gov Web site or in our reading room (see ADDRESSES above for a link to Regulations.gov and information on the location and hours of the reading room). Comments on the proposed rule were required to be received on or before June 3, 2016. We are reopening the comment period on Docket No. APHIS–2015– VerDate Sep<11>2014 17:00 Aug 25, 2016 Jkt 238001 0051 for an additional 30 days. We will also consider all comments received between June 4, 2016, and the date of this notice. This action will allow interested persons additional time to prepare and submit comments.

Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL–600–2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports of two cases where the main landing gear (MLG) failed to fully extend; it was determined that interference between the MLG door and the MLG fairing seal prevented the MLG door from opening fully. This proposed AD would require repetitive detailed inspections of the MLG fairing, fairing seal, door, and adjacent structures; and replacement or repair of affected parts and fasteners, or removal of the door, if necessary. This proposed AD would also require installation of a safety guide in the MLG fairing and an increase of the spacing between the MLG door and the fairing, which would terminate the repetitive inspections. We are proposing this AD to detect and correct interference between the MLG door and the MLG fairing seal. Such interference could result in a MLG failing to fully extend, which could cause an unsafe asymmetric landing configuration. DATES: We must receive comments on this proposed AD by October 11, 2016.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2015–30, dated January 13, 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– 600–2E25 (Regional Jet Series 1000) airplanes. The MCAI states: Two cases of main landing gear (MLG) failure to fully extend have been reported on model CL–600–2C10/–2D15/–2D24 aeroplanes. Investigation determined that interference between the MLG door and the MLG fairing seal prevented the MLG door from opening. Although model CL–600–2E25 aeroplanes feature new MLG door design, similar interference between the MLG door and the MLG fairing seal could exist on aeroplanes listed in the Applicability section of this [Canadian] AD. An MLG failing to extend may result in an unsafe asymmetric landing configuration. This [Canadian] AD mandates the repetitive inspection and rectification, as required, of the MLG fairing and seal, MLG door, and adjacent structures, until the mandatory terminating action is completed. The terminating action includes installation of a safety guide in the MLG fairing and an increase of the spacing between the MLG door and the fairing, which would terminate the repetitive inspections. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2016–8847. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 670BA–32–041, dated March 28, 2013. The service information describes procedures for detailed inspections of the MLG fairing, fairing seal, door, and adjacent structures; replacement or repair of affected parts and fasteners and removal of the door. We have also reviewed Bombardier Service Bulletin 670BA–32–049, May 26, 2015. The service information 58875 describes procedures for installation of a safety guide in the MLG fairing and an increase of the spacing between the MLG door and the fairing. 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 40 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspection and Installation ...... 50 work-hours × $85 per hour = $4,250 ................................ $0 $4,250 $170,000 We estimate the following costs to do any necessary replacements/removals that would be required based on the results of the proposed inspection. We have received no definitive data on the costs for the on-condition repairs that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need these replacements/removals/repairs: ON-CONDITION COSTS Action Labor cost Replacement of damaged fairing seal. Removal of MLG door Parts cost 6 work-hours × $85 per hour = $510 per seal replacement. 3 work-hours × $85 per hour = $255 per removal of MLG door. $921 per seal ......... $0 ........................... Cost on U.S. operators Cost per product $1,431 per seal replacement. $255 per removal of MLG door. $57,240 per seal replacement. $10,200 per removal of MLG door. OPTIONAL ACTIONS mstockstill on DSK3G9T082PROD with PROPOSALS Action Labor cost Parts cost Cost per product Cost on U.S. operators Installation of MLG door ...... 13 work-hours × $85 per hour = $1,105 ........................... $0 $1,105 $44,200 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 17:00 Aug 25, 2016 Jkt 238001 section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, E:\FR\FM\26AUP1.SGM 26AUP1 58876 Federal Register / Vol. 81, No. 166 / Friday, August 26, 2016 / Proposed Rules 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. 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.

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 CL-600-2E25 (Regional Jet Series 1000) 
airplanes. This proposed AD was prompted by reports of two cases where 
the main landing gear (MLG) failed to fully extend; it was determined 
that interference between the MLG door and the MLG fairing seal 
prevented the MLG door from opening fully. This proposed AD would 
require repetitive detailed inspections of the MLG fairing, fairing 
seal, door, and adjacent structures; and replacement or repair of 
affected parts and fasteners, or removal of the door, if necessary. 
This proposed AD would also require installation of a safety guide in 
the MLG fairing and an increase of the spacing between the MLG door and 
the fairing, which would terminate the repetitive inspections. We are 
proposing this AD to detect and correct interference between the MLG 
door and the MLG fairing seal. Such interference could result in a MLG 
failing to fully extend, which could cause an unsafe asymmetric landing 
configuration.

DATES: We must receive comments on this proposed AD by October 11, 
2016.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-30, dated January 13, 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-
2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

    Two cases of main landing gear (MLG) failure to fully extend 
have been reported on model CL-600-2C10/-2D15/-2D24 aeroplanes. 
Investigation determined that interference between the MLG door and 
the MLG fairing seal prevented the MLG door from opening.
    Although model CL-600-2E25 aeroplanes feature new MLG door 
design, similar interference between the MLG door and the MLG 
fairing seal could exist on aeroplanes listed in the Applicability 
section of this [Canadian] AD. An MLG failing to extend may result 
in an unsafe asymmetric landing configuration.
    This [Canadian] AD mandates the repetitive inspection and 
rectification, as required, of the MLG fairing and seal, MLG door, 
and adjacent structures, until the mandatory terminating action is 
completed.

    The terminating action includes installation of a safety guide in 
the MLG fairing and an increase of the spacing between the MLG door and 
the fairing, which would terminate the repetitive inspections. You may 
examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
8847.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 670BA-32-041, dated March 
28, 2013. The service information describes procedures for detailed 
inspections of the MLG fairing, fairing seal, door, and adjacent 
structures; replacement or repair of affected parts and fasteners and 
removal of the door. We have also reviewed Bombardier Service Bulletin 
670BA-32-049, May 26, 2015. The service information describes 
procedures for installation of a safety guide in the MLG fairing and an 
increase of the spacing between the MLG door and the fairing.
    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 40 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements/
removals that would be required based on the results of the proposed 
inspection. We have received no definitive data on the costs for the 
on-condition repairs that would be required based on the results of the 
proposed inspection. We have no way of determining the number of 
aircraft that might need these replacements/removals/repairs:

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,

[[Page 58876]]

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.

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-2016-8847; Directorate Identifier 
2016-NM-020-AD.

(a) Comments Due Date

    We must receive comments by October 11, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model CL-600-2E25 (Regional 
Jet Series 1000) airplanes, certificated in any category, serial 
numbers 19002 through 19041.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by reports of two cases where the main 
landing gear (MLG) failed to fully extend; it was determined that 
interference between the MLG door and the MLG fairing seal prevented 
the MLG door from opening fully. We are issuing this AD to detect 
and correct interference between the MLG door and the MLG fairing 
seal. Such interference could result in a MLG failing to fully 
extend, which could cause an unsafe asymmetric landing 
configuration.

(f) Compliance

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

(g) Inspection of MLG Fairing, Seal, Door, and Adjacent Structures

    Within 660 flight hours after the effective date of this AD, 
conduct a detailed inspection for damage to the MLG fairing, fairing 
seal, door, and adjunct structures, and for missing parts and 
fasteners, in accordance with Part A of the Accomplishment 
Instructions of Bombardier Service Bulletin 670BA-32-041, dated 
March 28, 2013. Repeat the inspection thereafter at intervals not to 
exceed 660 flight hours until the installation required by paragraph 
(m) of this AD is done.

(h) Replacement of MLG Fairing Seal or Door Removal

    If damage to the MLG fairing seal is found during any inspection 
required by paragraph (g) of this AD, before further flight, replace 
the seal, in accordance with Part B of the Accomplishment
