We propose to supersede Airworthiness Directive (AD) 2014-16- 02, for certain Bombardier, Inc. Model CL-600-1A11 (CL-600) airplanes. AD 2014-16-02 currently requires revising the airplane flight manual to prohibit thrust reverser operation, doing repetitive detailed inspections of both engine thrust reversers for cracks, and modifying the thrust reversers if necessary. The modification of the thrust reversers is also an optional terminating action for the repetitive inspections. Since we issued AD 2014-16-02, we have determined 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. We are proposing 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.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2014-16-
02, for certain Bombardier, Inc. Model CL-600-1A11 (CL-600) airplanes. 
AD 2014-16-02 currently requires revising the airplane flight manual to 
prohibit thrust reverser operation, doing repetitive detailed 
inspections of both engine thrust reversers for cracks, and modifying 
the thrust reversers if necessary. The modification of the thrust 
reversers is also an optional terminating action for the repetitive 
inspections. Since we issued AD 2014-16-02, we have determined 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. We 
are proposing 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.

DATES: We must receive comments on this proposed AD by February 8, 
2016.

Discussion

    On August 4, 2014, we issued AD 2014-16-02, Amendment 39-17926 (79 
FR 46968, August 12, 2014). AD 2014-16-02 requires actions intended to 
address an unsafe condition on certain Bombardier, Inc. Model CL-600-
1A11 (CL-600) airplanes. AD 2014-16-02 is parallel to Canadian AD CF-
2014-19, dated June 20, 2014, which additionally mandated repair or 
modification of the thrust reversers. At that time, we had determined 
that the compliance time for that action would allow enough time to 
provide notice and opportunity for prior public comment on the merits 
of the actions. The preamble to AD 2014-16-02 indicated we were 
considering further rulemaking to require repair or modification of the 
thrust reversers. We now have determined that further rulemaking is 
necessary.

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 Mandatory 
Continuing Airworthiness Information (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 the same type design.

Costs of Compliance

    We estimate that this proposed AD affects 18 airplanes of U.S. 
registry.
    The actions required by AD 2014-16-02, Amendment 39-17926 (79 FR 
46968, August 12, 2014), and retained in this proposed AD, take about 
29 work-hours per product, at an average labor rate of $85 per work-
hour. Based on these figures, the estimated cost of the actions that 
are required by AD 2014-16-02 is $2,465 per product.
    We also estimate that it would take about 100 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $509 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be $162,162, or $9,009 per 
product.
    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 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.

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 February 8, 2016.

(b) Affected ADs

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

(c) Applicability

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

    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 No Changes

    This paragraph restates the requirements of paragraph (g) of AD 
2014-16-02, Amendment 39-17926 (79 FR 46968, August 12, 2014), with 
no changes. 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), (g)(2), (g)(3), and 
(g)(4) 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), (g)(2), (g)(3), and (g)(4) of this AD, as

2014-16-02, Amendment 39-17926 (79 FR 46968, August 12, 2014), with 
no changes. Within 25 flight cycles or 90 days, whichever occurs 
first, after August 12, 2014 (the effective date of AD 2014-16-02), 
do detailed inspections (including a borescope inspection) of both 
engine thrust reversers for cracks, in accordance with the 
Accomplishment Instructions of Bombardier Alert Service Bulletin 
A600-0769, Revision 01, dated June 26, 2014.
    (1) If no cracking is found during any inspection required by 
paragraph (h) of this AD, repeat the inspection required by 
paragraph (h) of this AD thereafter at intervals not to exceed 100 
flight cycles until the repair or modification specified in 
paragraph (i) or (k) of this AD is done.
    (2) If any cracking is found during any inspection required by 
paragraph (h) of this AD, before further flight, modify the thrust 
reversers on both engines, in accordance with the Accomplishment

    This paragraph restates the requirements of paragraph (j) of AD 
2014-16-02, Amendment 39-17926 (79 FR 46968, August 12, 2014), with 
no changes. This paragraph provides credit for actions required by 
paragraphs (h) and (i) of this AD, if those actions were performed 
before August 12, 2014 (the effective date of AD 2014-16-02) using 
Bombardier Alert Service Bulletin A600-0769, dated June 19, 2014, 
which is not incorporated by reference in this AD.

(k) New Requirement of This AD: Repair/Modify

    Within 24 months after the effective date of this AD, repair or 
modify the thrust reversers on both engines, using a method approved 
by the Manager, New York Aircraft Certification Office (ACO), ANE-
