We are revising an earlier proposal to supersede Airworthiness Directive (AD) 2014-16-02 for certain Bombardier, Inc. Model CL-600- 1A11 (CL-600) airplanes. This action revises the notice of proposed rulemaking (NPRM) by reducing the compliance time to modify the thrust reversers, and adding new modification procedures. We are proposing this AD to address the unsafe condition on these products. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

Discussion

    We issued an NPRM to amend 14 CFR part 39 to supersede AD 2014-16-
02, Amendment 39-17926 (79 FR 46968, August 12, 2014) (``AD 2014-16-
02''). AD 2014-16-02 applies to certain Bombardier, Inc. Model CL-600-
1A11 (CL-600) airplanes. The NPRM published in the Federal Register on 
December 24, 2015 (80 FR 80293) (``the NPRM''). The NPRM was prompted 
by a determination that it is necessary to add a requirement to repair 
or modify the thrust reversers, which would terminate the requirements 
of AD 2014-16-02. The NPRM proposed to continue to require the actions 
specified in AD 2014-16-02. The NPRM also proposed to require repair or 
modification of the thrust reversers. This action revises the NPRM by 
reducing the compliance time to modify the thrust reversers, and adding 
new modification procedures.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM, Transport Canada Civil Aviation (TCCA), 
which is the aviation authority for Canada, issued Canadian 
Airworthiness Directive CF-2014-19R1, dated March 14, 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-600-1A11 (CL-600) airplanes. The MCAI states:

    There have been two reported incidents of partial deployment of 
an engine thrust reverser in-flight, caused by a failure of the 
translating sleeve at the thrust reverser actuator attachment 
points. Inspection of the same area on some other thrust reversers 
revealed cracks emanating from the holes under the nut plates.
    In both incidents, the affected aeroplane landed safely without 
any noticeable controllability issues, however structural failure of 
thrust reverser actuator attachment points resulting in thrust 
reverser deployment or dislodgment in flight is a safety hazard 
warranting an immediate mitigating action.
    To help in mitigating any immediate safety hazard, Bombardier 
Inc. has revised the Aircraft Flight Manual (AFM) through Temporary 
Revisions (TR) 600/29, 600/30, 600-1/24 and 600-1/26, to prohibit 
the thrust reverser operation on affected aeroplanes. Additionally, 
as an interim corrective action, Bombardier Inc. has issued alert 
service bulletin (ASB) A600-0769 requiring an inspection and/or a 
mechanical lock out of the thrust reverser to prevent it from moving 
out of forward thrust mode.
    Original [TCCA] Emergency AD CF-2014-19 was issued 20 June 2014 
to mandate the incorporation of above mentioned revised AFM 
procedures and compliance with ASB A600-0769. This [TCCA] AD is now 
being revised to include the terminating action in accordance with 
Part C of the ASB A600-0769 Rev 02 dated 22 February 2016.

    We reduced the compliance time for modification of the thrust 
reversers specified in paragraph (k) of this SNPRM to match the 
compliance time specified in the MCAI. We also added new procedures in 
paragraph (k) of this SNPRM for modifying the thrust reversers.
    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-2015-
7529.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Alert Service Bulletin A600-0769, Revision 
02, dated February 22, 2016. The service information describes 
procedures for modifying the thrust reversers on both engines. The 
modification includes inspections for cracks and elongated holes.
    We also reviewed the following TRs, which introduce procedures to 
prohibit thrust reverser operation. These documents are distinct since 
they apply to different airplane configurations.
     Canadair TR 600/29-2, dated January 18, 2016, to the 
Canadair CL-600-1A11 AFM.
     Canadair TR 600-1/24-2, dated January 18, 2016, to the 
Canadair CL-600-1A11 AFM (Winglets).
    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.

Comments

    We gave the public the opportunity to participate in developing 
this proposed AD. We considered the comments received.

Request To Cite Most Recent Service Information

    Bombardier, Inc. requested that we revise the proposed AD (in the 
NPRM) to cite the most recent AFMs. Bombardier, Inc. explained that the 
AFM TRs mentioned in paragraph (g) of the proposed AD (in the NPRM) 
have been revised to include AFM TRs 600/30-2, 600-1/26-2, 600/29-2, 
and 600-1/24-2, all dated January 18, 2016.
    We agree to refer to the revised AFM TRs that apply to U.S.-
registered airplanes in paragraphs (g)(1) and (g)(2) of this proposed 
AD. Those TRs are Canadair TR 600/29-2, dated January 18, 2016, to the 
Canadair CL-600-1A11 AFM; and Canadair TR 600-1/24-2, dated January 18, 
2016, to the Canadair CL-600-1A11 AFM (Winglets).
    Bombardier, Inc. also requested that we refer to Bombardier Alert 
Service Bulletin A600-0769, Revision 02, dated February 22, 2016, as 
described previously.
    We agree with the commenter's request. We revised the introductory 
text of paragraph (h) and paragraphs (h)(2), (i), and (k) of this 
proposed AD to refer to Bombardier Alert Service Bulletin A600-0769, 
Revision 02, dated February 22, 2016. We also clarified the

[[Page 89883]]

actions specified in paragraphs (h)(2) and (i) of this proposed AD by 
referring to Part B of Bombardier Alert Service Bulletin A600-0769, 
Revision 02, dated February 22, 2016, for the modification specified in 
those paragraphs.
    In addition, paragraph (k) of the proposed AD (in the NPRM) 
specified doing a repair or modification using a method approved by the 
Manager, New York Aircraft Certification Office (ACO), ANE-170, FAA; or 
Transport Canada Civil Aviation (TCCA); or Bombardier, Inc.'s TCCA 
Design Approval Organization (DAO). Because Part C of Bombardier Alert 
Service Bulletin A600-0769, Revision 02, dated February 22, 2016, is 
the appropriate source of service information for doing the terminating 
action (i.e., modifying the thrust reversers), we have revised 
paragraph (k) of this proposed AD to refer to that service information. 
However, under the provisions of paragraph (n)(1) of this proposed AD, 
we will consider requests for approval of other repairs or 
modifications if sufficient data are submitted to substantiate that the 
repair or modification would provide an acceptable level of safety.

Request To Specify Terminating Action

    Bombardier, Inc. requested that we revise paragraph (k) of the 
proposed AD (in the NPRM) to specify that doing the actions specified 
in that paragraph terminates the requirements of paragraph (g) of the 
proposed AD.
    We agree with the commenter's request. The MCAI states that 
accomplishing the modification in Part C of Bombardier Alert Service 
Bulletin A600-0769, Revision 02, dated February 22, 2016, terminates 
the inspections and interim modification. However, we have determined 
that accomplishing the actions in Part C of Bombardier Alert Service 
Bulletin A600-0769, Revision 02, dated February 22, 2016, also 
terminates the requirement for the AFM revisions specified in paragraph 
(g) of this proposed AD. The TRs specified in paragraph (g) of this 
proposed AD only apply to airplanes on which the actions specified in 
Part C of Bombardier Alert Service Bulletin A600-0769, Revision 02, 
dated February 22, 2016, have not been done. We have revised paragraph 
(k) of this proposed AD accordingly.

Request To Revise Phone Number and Email

    Bombardier, Inc. requested that we revise the NPRM to include 
revised contact information for the widebody customer response center.
    We agree and have revised the ADDRESSES section of this SNPRM and 
paragraph (o)(2) of this proposed AD accordingly.

FAA's Determination and Requirements of This SNPRM

    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.
    Certain changes described above expand the scope of the NPRM. As a 
result, we have determined that it is necessary to reopen the comment 
period to provide additional opportunity for the public to comment on 
this SNPRM.

Differences Between This SNPRM and the MCAI or Service Information

    Part C of Bombardier Alert Service Bulletin A600-0769, Revision 02, 
dated February 22, 2016, specifies to do certain inspections for cracks 
and elongated holes, but does not specify corrective actions for 
airplanes on which any crack or elongated hole is found. Paragraph (l) 
of this proposed AD would require that for any cracking or elongated 
hole, a repair be done using a method approved by the Manager, New York 
ACO, ANE-170, FAA; or TCCA; or Bombardier, Inc.'s TCCA DAO.

Costs of Compliance

    We estimate that this proposed AD would affect 18 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

                                         hour = $8,500.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary modifications 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of airplanes that might need 
this modification:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions for the inspections that 
are part of the new modification specified in this proposed AD.

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

[[Page 89884]]

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 removing Airworthiness Directive (AD) 
2014-16-02, Amendment 39-17926 (79 FR 46968, August 12, 2014), and 
adding the following new AD:

Bombardier, Inc.: Docket No. FAA-2015-7529; Directorate Identifier 
2014-NM-207-AD.

(a) Comments Due Date

    We must receive comments by January 27, 2017.

(b) Affected ADs

    This AD replaces AD 2014-16-02, Amendment 39-17926 (79 FR 46968, 
August 12, 2014) (``AD 2014-16-02'').

(c) Applicability

    This AD applies to Bombardier, Inc. Model CL-600-1A11 (CL-600) 
airplanes, certificated in any category, serial numbers 1004 through 
1085 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 78, Engine 
Exhaust.

(e) Reason

    This AD was prompted by reports of partial deployment of an 
engine thrust reverser in flight caused by a failure of the 
translating sleeve at the thrust reverser attachment points. We are 
issuing this AD to detect and correct cracks of the translating 
sleeve at the thrust reverser actuator attachment points, which 
could result in deployment or dislodgement of an engine thrust 
reverser in flight and subsequent reduced control of the airplane.

(f) Compliance

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

(g) Retained Airplane Flight Manual (AFM) Revision With Revised Service 
Information

    This paragraph restates the requirements of paragraph (g) of AD 
2014-16-02, with revised service information. Within 1 calendar day 
after August 12, 2014 (the effective date of AD 2014-16-02): Revise 
the applicable sections of the AFM to include the information 
specified in the temporary revisions (TRs) identified in paragraphs 
(g)(1) and (g)(2) of this AD, as applicable. These TRs introduce 
procedures to prohibit thrust reverser operation. Operate the 
airplane according to the limitations and procedures in the TRs 
identified in paragraphs (g)(1) and (g)(2) of this AD, as 
applicable. The revision required by paragraph (g) of this AD may be 
done by inserting copies of the applicable TRs identified in 
paragraphs (g)(1) and (g)(2) of this AD into the AFM. When these TRs 
have been included in the general revisions of the AFM, the general 
revisions may be inserted in the AFM, provided the relevant 
information in the general revision is identical to that in the 
applicable TRs, and the TRs may be removed.
    (1) Canadair TR 600/29-2, dated June 20, 2014, to the Canadair 
CL-600-1A11 AFM; or Canadair TR 600/29-2, dated January 18, 2016, to
