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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-03-
08, for 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 currently requires 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. Since we issued AD 2011-03-08, we determined 
that a terminating action is necessary to address the identified unsafe 
condition. This proposed AD would add a requirement for the terminating 
action. We are proposing this AD to address the unsafe condition on 
these products.

DATES: We must receive comments on this proposed AD by July 3, 2017.

Discussion

    On January 26, 2011, we issued AD 2011-03-08, Amendment 39-16592 
(76 FR 6536, February 7, 2011) (``AD 2011-03-08''), for 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 was 
prompted by reports of seven cases of on-ground hydraulic accumulator 
screw cap or end cap failure, which have resulted in loss of the 
associated hydraulic system and

[[Page 22767]]

high-energy impact damage to adjacent systems and structure. AD 2011-
03-08 requires 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. AD 2011-03-08 also 
requires repetitive ultrasonic inspections of the accumulators for 
cracks and replacement of any accumulator in which a crack is detected. 
We issued AD 2011-03-08 to detect and correct cracking of the 
accumulator, which could result in loss of the associated hydraulic 
system and high-energy impact damage to adjacent systems and structure, 
potentially resulting in fuel spillage, uncommanded flap movement, or 
loss of aileron control.
    Since we issued AD 2011-03-08, terminating action for the 
repetitive inspections has been developed. We have determined that a 
terminating action (relocation of the affected accumulators, and 
incorporation of new airworthiness limitations) is necessary to address 
the identified unsafe condition.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2009-42R2, dated June 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-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 the 
affected accumulators, and incorporating 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.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Bombardier, Inc., service information:
     Bombardier Canadair 215 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.

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 7 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 replacement 
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 replacement.

    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.

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) 
2011-03-08, Amendment 39-16592 (76 FR 6536, February 7, 2011) (``AD 
2011-03-08''), and adding the following new AD:

Bombardier, Inc. (Type Certificate Previously Held by Canadair 
Limited): Docket No. FAA-2017-0474; Directorate Identifier 2016-NM-
096-AD.

(a) Comments Due Date

    We must receive comments by July 3, 2017.

(b) Affected ADs

    This AD replaces AD 2011-03-08, Amendment 39-16592 (76 FR 6536, 
February 7, 2011) (``AD 2011-03-08'').

(c) Applicability

    This AD applies to Bombardier, Inc. (Type Certificate previously 
held by Canadair Limited) airplanes, certificated in any category, 
identified in paragraphs (c)(1) through (c)(3) of this AD.
    (1) Model CL-215-1A10 (CL-215) airplanes, serial numbers 1001 
through 1125 inclusive.

through 2990 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 29, Hydraulic 
power.

(e) Reason

    This AD was prompted by reports of on-ground hydraulic 
accumulator screw cap or end cap failure resulting in a loss of the 
associated hydraulic system and high-energy impact damage to 
adjacent systems and structure. We are issuing this AD to prevent 
failure of the screw cap or end cap, which could result in impact 
damage to various components, potentially resulting in fuel 
spillage, uncommanded flap movement, or loss of aileron control.

(f) Compliance

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

(g) Retained Inspection To Determine Flight Cycles, With No Changes

    This paragraph restates the requirements of paragraph (g) of AD 
2011-03-08, with no changes. Within 50 flight hours after March 14, 
2011 (the effective date of AD 2011-03-08), inspect to determine the 
number of flight cycles accumulated by each of the applicable 
accumulators (i.e., brake, aileron, elevator, and rudder 
accumulators) having part number 08-8423-010 (MS28700-3) installed 
on the airplane. A review of airplane maintenance records is 
acceptable in lieu of this inspection if the number of flight cycles 
accumulated can be conclusively determined from that review.

accumulator with a serviceable accumulator, in accordance with Part 
B of the Accomplishment Instructions of the applicable Bombardier 
service bulletin listed in table 1 to paragraphs (h), (i), and (k) 
of this AD. Doing the replacement does not end the inspection 
requirements of paragraphs (h) and (i) of this AD. Repeat the 
inspections required by paragraph (h) or (i) of this AD, as 
applicable, at intervals not to exceed 750 flight cycles until the 
actions required by paragraphs (n), (o), and (p) of this AD have 
been done.

(o) New Establishment of Accumulator Number of Flight Hours and 
Determination of Previous Use of the Accumulator

    Within 12 months after the effective date of this AD, establish 
the number of flight hours for each accumulator, and determine 
whether any accumulator has been used in service on another type of 
airplane other than Model CL-215-1A10 (CL-215), CL-215-6B11 (CL-215T 
Variant), and CL-215-6B11 (CL-415 Variant), in accordance with the 
Accomplishment Instructions in the applicable Bombardier service 
bulletin specified in table 4 to paragraph (o) of this AD. If any 
accumulator is found that has been in service on another type of 
airplane other than Model CL-215-1A10 (CL-215), CL-215-6B11 (CL-215T 
Variant), or CL-215-6B11 (CL-415 Variant), replace the accumulator 
within 50 flight hours after determining an affected accumulator is 
installed.
