Airworthiness Directives; C Series Aircraft Limited Partnership 
(CSALP) (Type Certificate Previously Held by Bombardier, Inc.) 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
C Series Aircraft Limited Partnership (CSALP) Model BD-500-1A10 and BD-
500-1A11 airplanes. This AD was prompted by reports of dislodged cargo 
compartment blowout panels. This AD requires repetitive inspections for 
any dislodged blow-out panel in the forward and aft cargo compartments, 
reporting of the inspection findings, and reinstallation if necessary. 
We are issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective January 14, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of certain publication listed in this AD as of January 14, 
2019.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain C Series Aircraft 
Limited Partnership (CSALP) Model BD-500-1A10 and BD-500-1A11 
airplanes. The NPRM published in the Federal Register on September 19, 
2018 (83 FR 47315). The NPRM was prompted by reports of dislodged cargo 
compartment blowout panels. The NPRM proposed to require repetitive 
inspections for any dislodged blow-out panel in the forward and aft 
cargo compartments, reporting of the inspection findings, and 
reinstallation if necessary.
    We are issuing this AD to address dislodged cargo compartment blow-
out panels, which could result in openings in the forward and aft cargo 
compartments. In the event of a cargo compartment fire, these 
unintended openings in the forward and aft cargo compartments would 
provide a path for smoke, fire, and Halon to enter the adjacent 
equipment bays, flight deck, and passenger cabin, which could delay 
smoke detection in the forward and aft cargo compartments and result in 
the forward and aft cargo compartments not being able to maintain the 
Halon concentration required for fire suppression. The cargo 
compartment fire may become uncontrollable if this condition is not 
addressed, which could result in the loss of controllability of the 
airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2018-15, dated June 6, 
2018 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain C Series Aircraft Limited Partnership (CSALP) Model BD-500-1A10 
and BD-500-1A11 airplanes. The MCAI states:

    Multiple events of dislodged cargo compartment blow-out panels 
have been reported in-service. It was determined that these events 
were caused by baggage impacting the cargo panel cage, or the cargo 
compartment liner below the cargo panel cage, during baggage loading 
and unloading on the ground, or during flight due to shifting 
luggage.
    Dislodged cargo compartment blow-out panels create openings in 
the forward and aft cargo compartments. In the event of a cargo 
compartment fire, these unintended openings in the forward and aft 
cargo compartments would provide a path for smoke, fire, and Halon 
to enter the adjacent equipment bays, flight deck, and passenger 
cabin, which could delay smoke detection in the forward and aft 
cargo compartments and result in the forward and aft cargo 
compartments not being able to maintain Halon concentration required 
for fire suppression. The cargo compartment fire may become 
uncontrollable if this condition is not corrected.
    This [TCCA] AD mandates repetitive [detailed] inspections of the 
affected forward and aft cargo compartment blow-out panels, and 
reporting of inspection findings where dislodged blow-out panels 
have been found [and re-installation of dislodged blow-out panels].

    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 
0799.

Comments

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

Change to Product Name

    The type certificate holder for Model BD-500-1A10 and BD-500-1A11 
airplanes has changed from ``Bombardier, Inc.,'' to ``C Series Aircraft 
Limited Partnership (CSALP).'' We have revised this AD accordingly.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule with the change 
described previously and minor editorial changes. We have determined 
that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

check,'' Issue 002, dated May 16, 2018. This service information 
describes procedures for an inspection for any dislodged blow-out panel 
in the forward and aft cargo compartments.
    Bombardier has issued C Series Data Module BD500-A-J50-10-01-00AAA-
521A-A, ``Decompression panels dislodging--Return to basic 
configuration,'' Issue 002, dated May 16, 2018. This service 
information describes procedures for re-installation of dislodged 
forward and aft cargo compartment blow-out panels.
    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 affects 21 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85           $1,785
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
action that would be required based on the results of any required 
actions. We have no way of determining the number of aircraft that 
might need this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                               Cost per
                   Labor cost                     Parts cost    product
------------------------------------------------------------------------
2 work-hours x $85 per hour = $170..............         $0        $170
------------------------------------------------------------------------

    We estimate that it would take about 1 work-hour per product to 
comply with the on-condition reporting requirement in this AD. The 
average labor rate is $85 per hour. Based on these figures, we estimate 
the cost of reporting the inspection results on U.S. operators to be 
$85 per product.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW, Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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):

2018-25-04 C Series Aircraft Limited Partnership (CSALP) (Type 
Certificate Previously Held by Bombardier, Inc.): Amendment 39-
19515; Docket No. FAA-2018-0799; Product Identifier 2018-NM-117-AD.

[[Page 63399]]

(a) Effective Date

    This AD is effective January 14, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to C Series Aircraft Limited Partnership (CSALP) 
(Type Certificate Previously Held by Bombardier, Inc.) airplanes, 
certificated in any category, identified in paragraphs (c)(1) and 
(c)(2) of this AD.
    (1) Model BD-500-1A10 airplanes, serial numbers 50001 and 
subsequent, equipped with blow-out panel part number D762213-503, 
D762216-505, or D762209-503.

subsequent, equipped with blow-out panel part number D762213-503, 
D762216-505, or D762209-503.

(d) Subject

    Air Transport Association (ATA) of America Code 50, Cargo and 
accessory compartment.

(e) Reason

    This AD was prompted by reports of dislodged cargo compartment 
blow-out panels. We are issuing this AD to address this condition, 
which could result in openings in the forward and aft cargo 
compartments. In the event of a cargo compartment fire, these 
unintended openings in the forward and aft cargo compartments would 
provide a path for smoke, fire, and Halon to enter the adjacent 
equipment bays, flight deck, and passenger cabin, which could delay 
smoke detection in the forward and aft cargo compartments and result 
in the forward and aft cargo compartments not being able to maintain 
the Halon concentration required for fire suppression. The cargo 
compartment fire may become uncontrollable if this condition is not 
addressed, which could result in the loss of controllability of the 
airplane.

(f) Compliance

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

(g) Repetitive Inspections of the Forward and Aft Cargo Compartment 
Blow-Out Panels and Re-Installation

    Within 7 days or 50 flight cycles, whichever occurs first, after 
the effective date of this AD, do a detailed inspection for any 
dislodged blow-out panel in the forward and aft cargo compartments, 
in accordance with C Series (Bombardier) Data Module BD500-A-J50-10-
01-01AAA-310B-A, ``Forward and aft cargo compartment blow-out 
panels--Visual check,'' Issue 002, dated May 16, 2018. Re-install 
all dislodged forward and aft cargo compartment blow-out panels 
before further flight, in accordance with C Series (Bombardier) Data 
Module BD500-A-J50-10-01-00AAA-521A-A, ``Decompression panels 
dislodging--Return to basic configuration,'' Issue 002, dated May 
16, 2018. Thereafter, at intervals not to exceed 100 flight cycles, 
repeat the detailed inspection for any dislodged blow-out panel in 
the forward and aft cargo compartments.

(h) Reporting

    If any blow-out panel in the forward or aft cargo compartments 
is found dislodged during any inspection required by paragraph (g) 
of this AD, at the applicable time specified in paragraph (h)(1) or 
(h)(2) of this AD, report findings to the Bombardier customer 
response center (CRC) via email: [email protected]. 
Reportable findings include the airplane serial number on which any 
dislodged blow-out panel was found, the date of inspection, and the 
part number and location of each dislodged blow-out panel.
    (1) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (2) If the inspection was done before the effective date of this 
AD: Submit the report within 30 days after the effective date of 
this AD.

(i) Paperwork Reduction Act Burden Statement

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty 
for failure to comply with a collection of information subject to 
the requirements of the Paperwork Reduction Act unless that 
collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 1 hour per response, including the 
time for reviewing instructions, completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Comments concerning the accuracy of this 
burden and suggestions for reducing the burden should be directed to 
the FAA at: 800 Independence Ave. SW, Washington, DC 20591, Attn: 
Information Collection Clearance Officer, AES-200.
