SUPPLEMENTARY INFORMATION: 



Discussion



    Transport Canada Civil Aviation (TCCA), which is the aviation 

authority for Canada, has issued Canadian Airworthiness Directive CF-

2016-35, dated November 16, 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:



    It is possible for the shrouds of the High Pressure (HP) bleed 

air ducts located in the main wheel wells and overwing areas to 

deteriorate and consequently, their maximum permitted leakage rate 

could be exceeded. If a significant bleed air leak is not sensed by 

the detection system, hot air impingement may cause damage to the 

adjacent structure and system components or create a fire hazard.

    This [Canadian] AD is issued to mandate a modification of the 

bleed-air duct and detection system, as well as a revision of the 

Airworthiness Limitation tasks to correspond with this modification.



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

0699.

FAA's Determination and Requirements of This 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 issuing this AD because we 

evaluated all pertinent information and determined the unsafe condition 

exists and is likely to exist or develop on other products of the same 

type design.

    This AD requires revisions to certain operator maintenance 

documents to include new actions (e.g., inspections). Compliance with 

these actions is required by 14 CFR 91.403(c). For airplanes that have 

been previously modified, altered, or repaired in the areas addressed 

by this AD, the operator may not be able to accomplish the actions 

described in the revisions. In this situation, to comply with 14 CFR 

91.403(c), the operator must request approval for an alternative method 

of compliance according to paragraph (k)(1) of this AD. The request 

should include a description of changes to the required inspections 

that will ensure the continued operational safety of the airplane.



FAA's Determination of the Effective Date



    Since there are currently no domestic operators of this product, 

notice and opportunity for public comment before issuing this AD are 

unnecessary.



Comments Invited



    This AD is a final rule that involves requirements affecting flight 

safety, and we did not precede it by notice and opportunity for public 

comment. We invite you to send any written relevant data, views, or 

arguments about this AD. Send your comments to an address listed under 

the ADDRESSES section. Include ``Docket No. FAA-2017-0699; Directorate 

Identifier 2017-NM-004-AD'' at the beginning of your comments. We 

specifically invite comments on the overall regulatory, economic, 

environmental, and energy aspects of this AD. We will consider all 

comments received by the closing date and may amend this AD based on 

those comments.

    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 

will also post a report summarizing each substantive verbal contact we 

receive about this AD.



Costs of Compliance



    We estimate that this AD affects 0 airplanes of U.S. registry.

    We also estimate that it will take about 91 work-hours per product 

to comply with the basic requirements of this AD. The average labor 

rate is $85 per work-hour. Required parts cost are not available. Based 

on these figures, we estimate the cost of this AD on U.S. operators to 

be $0, or $7,735 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



[[Page 39343]]



products identified in this rulemaking action.



Regulatory Findings



    We determined that this AD will not have federalism implications 

under Executive Order 13132. This AD will 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 that this AD:

    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.

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

directive (AD):



2017-15-08 Bombardier, Inc.: Amendment 39-18968; Docket No. FAA-

2017-0699; Directorate Identifier 2017-NM-004-AD.



(a) Effective Date



    This AD becomes effective September 5, 2017.



(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 19001 through 19048 inclusive.



(d) Subject

(e) Reason



    This AD was prompted by a report of a possibility that the 

shrouds of the high pressure bleed air ducts could deteriorate and 

their maximum permitted leakage rate could be exceeded. We are 

issuing this AD to prevent a bleed air leak from exceeding the 

maximum permitted leakage rate, which if not sensed by the detection 

system, could cause hot air impingement to damage the adjacent 

structure and system components or create a fire hazard.



(f) Compliance



    Comply with this AD within the compliance times specified, 

unless already done.



(g) Modification



    At the earlier of the times specified in paragraphs (g)(1) and 

(g)(2) of this AD: Modify the bleed-air duct and detection system, 

in accordance with the Accomplishment Instructions of Bombardier 

Service Bulletin 670BA-36-022, Revision B, dated December 20, 2016.

first after the effective date of this AD.

    (2) Within the next 10,000-flight-hours scheduled maintenance 

check after the effective date of this AD.



(h) Maintenance or Inspection Program Revision



    Within 30 days after the effective date of this AD: Revise the 

maintenance or inspection program, as applicable, by incorporating 

the service information specified in figure 1 to paragraph (h) of 

this AD. The initial compliance time for tasks 28-12-00-601 and 28-

12-00-602 is at the later of the applicable times specified in the 

service information specified in figure 1 to paragraph (h) of this 

AD, or within 30 days after the effective date of this AD, whichever 

occurs later. The initial compliance times for tasks 25-85-00-101, 

36-20-00-101, and 36-20-00-102 are specified in Figure 2 to 

paragraph (h) of this AD. When these temporary revisions (TRs) have 

been included in general revisions of the maintenance requirement 

manual (MRM), the general revisions may be inserted in the MRM, 

provided the relevant information in the general revision is 

identical to the TRs specified in figure 1 to paragraph (h) of this 

AD.
