Airworthiness Directives; Viking Air Limited (Type Certificate 
Previously Held by Bombardier, Inc.; Canadair Limited) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2011-03-08, 
which applied to certain Bombardier, Inc., Model CL-215-1A10 (CL-215), 
CL-215-6B11 (CL-215T Variant), and CL-215-6B11 (CL-415 Variant) 
airplanes. AD 2011-03-08 required an inspection to determine the number 
of flight cycles accumulated by certain accumulators installed on the 
airplane, and repetitive inspections of the accumulators for cracks, 
and replacement if necessary. This AD retains those inspections and the 
accumulator replacement if necessary, and adds a new terminating action 
to address the identified unsafe condition. This AD was prompted by the 
development of a terminating action for the repetitive inspections. We 
are issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective October 11, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 11, 
2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of March 
14, 2011 (76 FR 6536, February 7, 2011).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2011-03-08, Amendment 39-16592 (76 FR 6536, 
February 7, 2011) (``AD 2011-03-08''). AD 2011-03-08 applied to certain 
Bombardier, Inc., Model CL-215-1A10 (CL-215), CL-215-6B11 (CL-215T 
Variant), and CL-215-6B11 (CL-415 Variant) airplanes. The NPRM 
published in the Federal Register on May 18, 2017 (82 FR 22766). The 
NPRM was prompted by the development of a terminating action 
(relocation of the affected accumulators, and incorporation of new 
airworthiness limitations), which addresses the unsafe condition. The 
NPRM proposed to continue to require an inspection to determine the 
number of flight cycles accumulated by applicable accumulators (i.e., 
brake, aileron, elevator, and rudder accumulators) installed on the 
airplane, repetitive ultrasonic inspections of the accumulators for 
cracks, and

[[Page 42025]]

replacement of any accumulator in which a crack is detected. The NPRM 
also proposed to require a new terminating action for the repetitive 
inspections. We are issuing this AD to prevent failure of the screw cap 
or end cap of certain accumulators, which could result in impact damage 
to various components, potentially resulting in fuel spillage, 
uncommanded flap movement, or loss of aileron control.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2009-42R2, dated May 30, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ''the MCAI''), to correct an 
unsafe condition for certain Viking Air Limited Model CL-215-1A10 (CL-
215), CL-215-6B11 (CL-215T Variant), and CL-215-6B11 (CL-415 Variant) 
airplanes. The MCAI states:

    Seven cases of on-ground hydraulic accumulator screw cap or end 
cap failure have been experienced on CL-600-2B19 (CRJ) aeroplane, 
resulting in loss of the associated hydraulic system and high-energy 
impact damage to adjacent systems and structure. To date, the lowest 
number of flight cycles accumulated at the time of failure has been 
6991.
    Although there have been no failures to date on any CL-215-1A10 
(CL-215) or CL-215-6B11 (CL-215T and CL-415) aeroplane, similar 
accumulators, Part Number (P/N) 08-8423-010 (MS28700-3), to those 
installed on the CL-600-2B19, are installed on the aeroplane models 
listed in the Applicability section of this [Canadian] AD.
    A detailed analysis of the systems and structure in the 
potential line of trajectory of a failed screw cap/end cap for each 
accumulator has been conducted. It has identified that the worst-
case scenarios would be impact damage to various components, 
potentially resulting in fuel spillage, uncommanded flap movement, 
or loss of aileron control.
    This [Canadian] AD mandates repetitive [ultrasonic] inspections 
of the accumulators for cracks and replacement of any accumulator in 
which a crack is detected.
    Revision 1 of this [Canadian] AD clarified the text of the 
[Canadian] AD, including the P/N of the affected accumulators.
    This revision provides the terminating action [relocation of 
affected accumulators and incorporation of new airworthiness 
limitations] to this [Canadian] AD. It also modifies the 
applicability range for the CL-215-1A10 (CL-215); the CL-215 is out 
of production and the last aeroplane produced was serial number 
1125.

    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-2017-
0474.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Explanation of Changes Made to This Final Rule

    We have revised this final rule to identify the legal name of the 
manufacturer as published in the most recent type certificate data 
sheet for the affected airplane models.
    In the proposed AD, we inadvertently listed the wrong publication 
dates for service information in two places. Table 4 to paragraph (o) 
of the proposed AD referred to Bombardier Service Bulletin 215-4470, 
Revision 1, dated December 13, 2013. We have corrected the publication 
date for this document to June 27, 2014, in this AD. Additionally, 
paragraph (r)(1)(iii) of the proposed AD referred to Bombardier Service 
Bulletin 215-3158, dated March 28, 2012. We have corrected the 
publication date for this document to March 21, 2012, in this AD.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD with the changes described 
previously and minor editorial changes. We have determined that these 
changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., has issued the following service information:
     Bombardier Service Bulletin 215-552, Revision 2, dated 
June 18, 2015. This service information describes procedures to 
relocate the aileron hydraulic accumulator aft of its current location.
     Bombardier Service Bulletin 215-3158, Revision 2, dated 
April 15, 2014; and Bombardier Service Bulletin 215-4423, Revision 5, 
dated March 17, 2016. This service information describes procedures to 
relocate the aileron, elevator, and rudder hydraulic accumulators aft 
and outboard of their current locations. These documents are distinct 
since they apply to different airplane models.
     Bombardier Service Bulletin 215-557, Revision 1, dated 
June 27, 2014; Bombardier Service Bulletin 215-3182, Revision 1, dated 
June 27, 2014; and Bombardier Service Bulletin 215-4470, Revision 1, 
dated June 27, 2014. This service information describes procedures to 
establish the number of flight hours for each accumulator and determine 
if it has been used on another type of aircraft. These documents are 
distinct since they apply to different airplane models.
     Bombardier Temporary Revision 5-56, dated December 13, 
2013; Bombardier Temporary Revision 295/7, dated December 13, 2013; 
Bombardier Temporary Revision LLC-1, dated December 13, 2013; and 
Bombardier Temporary Revision LLC-3, dated December 13, 2013. This 
service information provides a 10,000-hour accumulator life limitation 
for certain accumulators. These documents are distinct since they apply 
to different airplane models.
    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.

Costs of Compliance

    We estimate that this AD affects 7 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    According to the manufacturer, some of the costs of this 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
