We propose to supersede Airworthiness Directive (AD) 2012-25- 02, which applies to certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2012-25-02 requires revising the airworthiness limitations section (AWL) of the instructions for continued airworthiness (ICA) of the maintenance requirements manual by incorporating new procedures for repetitive inspections for cracking of the rear pressure bulkhead (RPB). AD 2012- 25-02 also requires revising the maintenance program to incorporate a revised task which requires an improved non-destructive inspection procedure. Since we issued AD 2012-25-02, additional in-service crack findings resulted in the development of a structural modification to the RPB. This proposed AD would mandate modification of the RPB and would add repetitive inspections for cracking of the RPB web, which would terminate certain actions in this proposed AD. We are proposing this AD to address the unsafe condition on these products.

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) 2012-25-
02, which applies to certain Bombardier, Inc. Model CL-600-2B19 
(Regional Jet Series 100 & 440) airplanes. AD 2012-25-02 requires 
revising the airworthiness limitations section (AWL) of the 
instructions for continued airworthiness (ICA) of the maintenance 
requirements manual by incorporating new procedures for repetitive 
inspections for cracking of the rear pressure bulkhead (RPB). AD 2012-
25-02 also requires revising the maintenance program to incorporate a 
revised task which requires an improved non-destructive inspection 
procedure. Since we issued AD 2012-25-02, additional in-service crack 
findings resulted in the development of a structural modification to 
the RPB. This proposed AD would mandate modification of the RPB and 
would add repetitive inspections for cracking of the RPB web, which 
would terminate certain actions in this proposed AD. We are proposing 
this AD to address the unsafe condition on these products.

Discussion

    We issued AD 2012-25-02, Amendment 39-17283 (77 FR 73902, December 
12, 2012) (``AD 2012-25-02''), for certain Bombardier, Inc. Model CL-
600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2012-25-02 
requires revising the AWL of the ICA of the Canadair Regional Jet 
Maintenance Requirements Manual by incorporating new procedures for 
repetitive detailed and special detailed inspections for cracking of 
the RPB. AD 2012-25-02 also requires revising the maintenance program 
to incorporate a revised task specified in a certain temporary 
revision, which requires an improved non-destructive inspection 
procedure; and adds airplanes to the applicability. AD 2012-25-02 
resulted from multiple reports of cracks on the forward face of the RPB 
web. We issued AD 2012-25-02 to detect and correct cracking in the RPB, 
which could result in reduced structural integrity and rapid 
decompression of the airplane.

Actions Since AD 2012-25-02 Was Issued

    Since we issued AD 2012-25-02, additional in-service crack findings 
resulted in the development of a structural modification to the RPB.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2011-30R2, dated June 12, 2017 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model CL-600-2B19 
(Regional Jet Series 100 & 440) airplanes. The MCAI states:

    Cracks on the forward face of the Rear Pressure Bulkhead (RPB) 
web have been discovered on three CL-600-2B19 aeroplanes in-service.
    A Temporary Revision has been made to Part 2 of the Maintenance 
Requirements Manual (MRM) to revise the existing AWL task by 
introducing an improved Non-Destructive Inspection (NDI) procedure 
to ensure that fatigue cracking of the RPB is detected and 
corrected.
    The original issue of this [TCCA] AD [which corresponds to FAA 
AD 2012-25-02] mandated the incorporation of a new NDI procedure for 
AWL task number 53-61-153.
    Additional in-service findings have resulted in the issue of 
revision 1 of this [TCCA] AD, which mandates a structural 
modification to the rear pressure bulkhead with revised threshold 
and repeat inspection intervals. This modification is intended to 
preclude the onset of multiple site fatigue damage for the remaining 
service life of the aeroplane. If not corrected, a failure of the 
RPB could result in loss of structural integrity of the aeroplane.
    Revision 2 of this [TCCA] AD requires an inspection to be 
carried out prior to modification of the RPB. This revision also 
requires an additional modification to be completed on the RPB prior 
to terminating AWL task number 53-61-153. It also includes 
provisions to account for certain repairs as well as [alternative 
methods of compliance] AMOCs issued to earlier revisions of this 
[TCCA] AD.

    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-2018-
0794.

     Bombardier REO 601R-53-61-5828, Revision A, dated March 
16, 2017. This service information describes procedures for a repair to 
FS 621.00 pressure bulkhead web at left buttock line (LBL) 27.5.
    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.

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 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 proposed 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 (p)(1) of this proposed AD. 
The request should include a description of changes to the required 
actions that will ensure the continued damage tolerance of the affected 
structure.

Differences Between This Proposed AD and the Service Information

    The MCAI includes the following statement: ``If it is not possible 
to complete all of the instructions in the SBs [service bulletins] . . 
. due to the configuration of the aircraft, contact Bombardier Inc. for 
approved instructions.'' This issue is addressed in 14 CFR 39.17, which 
states that ``If a change in a product affects your ability to 
accomplish the actions required by the AD in any way, you must request 
FAA approval of an alternative method of compliance . . .'' Since we do 
not currently have the authority to delegate AMOC approvals to foreign 
civil aviation authorities, the FAA is responsible for these approvals.

Costs of Compliance

    We estimate that this proposed AD affects 457 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

[[Page 46430]]



                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 917 work-hours x $85 per hour =  Up to $6,000...........  Up to $83,945..........  Up to $38,362,865.
 Up to $77,945.
----------------------------------------------------------------------------------------------------------------

    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions 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 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 proposed 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 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.
