SUPPLEMENTARY INFORMATION: Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2019–13, dated April 4, 2019 (‘‘Canadian AD CF–2019–13’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain De Havilland Aircraft of Canada Limited Model DHC–8–400, –401, and –402 airplanes. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0702. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain De Havilland Aircraft of Canada Limited Model DHC–8–400 series airplanes. The NPRM was published in the Federal Register on October 4, 2019 (84 FR 53070). The NPRM was prompted by a report of a quality escape in the manufacturing of APD switches, which consisted of the presence of contamination on the switch contact pin. The NPRM proposed to require identification and testing, and reidentification or replacement if necessary, of affected APDs. The FAA is issuing this AD to address such PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 6749 contamination that could insulate the contact pin from the diaphragm and result in an undetected fire or late detection of a fire. See the MCAI for additional background information. Comments The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Request To Update Type Certificate (TC) Holder Bombardier Aviation reported that ownership of the affected airplanes was transferred to De Havilland Aircraft of Canada Limited. Bombardier requested that the FAA revise the NPRM to identify De Havilland as the U.S. TC holder. The FAA acknowledges the change of ownership identified by the commenter and has revised this final rule accordingly. The FAA also notes that any future revisions to the referenced service information, Bombardier Service Bulletin 84–26–19, Revision ‘A,’ dated February 11, 2019, will be issued by De Havilland Aircraft of Canada Limited. Request To Limit Required Actions Horizon Air requested that the FAA revise the proposed AD to limit the required actions to those specified in paragraph 3.B., ‘‘Procedure,’’ of Bombardier Service Bulletin 84–26–19, Revision ‘A,’ dated February 11, 2019. Horizon noted that the proposed AD would require ‘‘the Accomplishment Instructions’’ of the service information, which also includes paragraph 3.A., ‘‘Job Set-Up,’’ and paragraph 3.C., ‘‘Close Out.’’ Horizon Air stated that those sections do not directly correct the unsafe condition. The FAA agrees with the commenter’s request and has revised paragraph (h) of this AD accordingly. Request To Remove Requirement To Return Failed APDs Horizon Air requested that the FAA remove paragraph (i) of the proposed AD (‘‘Return of Failed APDs’’). Horizon Air alleged that this requirement would place an unnecessary cost and regulatory burden on operators who must create, track, and maintain records to demonstrate compliance with the required return criteria. Horizon Air added that return of any failed loop (APD) could be done via operators’ field service/product support network with Kidde Aerospace and Defense (part of United Technologies Aerospace Systems (UTAS)). Horizon further asserted that E:\FR\FM\06FER1.SGM 06FER1 6750 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations the FAA did not justify the proposed requirement to return failed APDs to Kidde Aerospace and Defense or explain how this would improve the level of safety. The FAA does not agree that the requirement to return failed APDs to Kidde Aerospace and Defense places an unnecessary cost and regulatory burden on operators. Bombardier Service Bulletin 84–26–19, Revision ‘A,’ dated February 11, 2019, refers to Kidde Aerospace and Defense Service Bulletin 10–1096–26–511, Paragraph 3.3.F, which specifies returning the part with a Return Authorization form to Kidde Aerospace and Defense so that operators can receive a free-of-charge replacement. The cost of an APD varies from $6,300 to $9,300, depending on the type. With seven APDs on the aircraft, it is actually a cost benefit to return failed APDs to obtain replacements free of charge. In addition, when an unsafe condition involves an escape in a manufacturer’s quality control (QC) system, returning failed parts or reporting certain findings can be instrumental in determining the extent and nature of the QC problem, especially in cases where the data may not be available through other established means. The information collected from the return of the failed APDs is necessary to ensure that proper corrective action will be taken. The FAA has not changed this AD regarding this issue. Additional Change to Proposed AD Paragraph (j) of the proposed AD (‘‘Parts Installation Limitation’’) would allow installation of an affected APD if it is successfully tested and reidentified in accordance with Bombardier Service Bulletin 84–26–19, Revision ‘A,’ dated February 11, 2019. We have revised paragraph (j) in this AD to also allow installation of an affected APD that is tested and reidentified in accordance with Bombardier Service Bulletin 84– 26–19, dated October 24, 2018. Conclusion The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. The FAA has 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. The FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 Bombardier issued Service Bulletin 84–26–19, Revision ‘A,’ dated February 11, 2019. This service information describes procedures for identification and testing, and reidentification or replacement if necessary, of affected APDs. 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 The FAA estimates that this AD affects 65 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Up to 10 work-hours × $85 per hour = Up to $850 The FAA estimates the following costs to do any necessary on-condition actions that would be required based on Cost on U.S. operators Parts cost Cost per product $0 Up to $850 ............................................................... the results of any required actions. The FAA has no way of determining the Up to $55,250. number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS * Labor cost Parts cost Up to 124 work-hours × $85 per hour = Up to $10,540 ......................................... Up to $51,076 ........................................ Cost per product Up to $61,616. * The FAA has received no definitive data to provide cost estimates for the on-condition return of parts, except the FAA estimates that it would take about 1 work-hour per product to comply with the associated paperwork necessary for the return of parts. lotter on DSKBCFDHB2PROD with RULES According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate. 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 VerDate Sep<11>2014 19:34 Feb 05, 2020 Jkt 250001 requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-13, dated April 4, 
2019 (``Canadian AD CF-2019-13'') (also referred to as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain De Havilland Aircraft of Canada Limited 
Model DHC-8-400, -401, and -402 airplanes. You may examine the MCAI in 
the AD docket on the internet at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2019-0702.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain De Havilland 
Aircraft of Canada Limited Model DHC-8-400 series airplanes. The NPRM 
was published in the Federal Register on October 4, 2019 (84 FR 53070). 
The NPRM was prompted by a report of a quality escape in the 
manufacturing of APD switches, which consisted of the presence of 
contamination on the switch contact pin. The NPRM proposed to require 
identification and testing, and reidentification or replacement if 
necessary, of affected APDs. The FAA is issuing this AD to address such 
contamination that could insulate the contact pin from the diaphragm 
and result in an undetected fire or late detection of a fire. See the 
MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Request To Update Type Certificate (TC) Holder

    Bombardier Aviation reported that ownership of the affected 
airplanes was transferred to De Havilland Aircraft of Canada Limited. 
Bombardier requested that the FAA revise the NPRM to identify De 
Havilland as the U.S. TC holder.
    The FAA acknowledges the change of ownership identified by the 
commenter and has revised this final rule accordingly. The FAA also 
notes that any future revisions to the referenced service information, 
Bombardier Service Bulletin 84-26-19, Revision `A,' dated February 11, 
2019, will be issued by De Havilland Aircraft of Canada Limited.

Request To Limit Required Actions

    Horizon Air requested that the FAA revise the proposed AD to limit 
the required actions to those specified in paragraph 3.B., 
``Procedure,'' of Bombardier Service Bulletin 84-26-19, Revision `A,' 
dated February 11, 2019. Horizon noted that the proposed AD would 
require ``the Accomplishment Instructions'' of the service information, 
which also includes paragraph 3.A., ``Job Set-Up,'' and paragraph 3.C., 
``Close Out.'' Horizon Air stated that those sections do not directly 
correct the unsafe condition.
    The FAA agrees with the commenter's request and has revised 
paragraph (h) of this AD accordingly.

Request To Remove Requirement To Return Failed APDs

    Horizon Air requested that the FAA remove paragraph (i) of the 
proposed AD (``Return of Failed APDs''). Horizon Air alleged that this 
requirement would place an unnecessary cost and regulatory burden on 
operators who must create, track, and maintain records to demonstrate 
compliance with the required return criteria. Horizon Air added that 
return of any failed loop (APD) could be done via operators' field 
service/product support network with Kidde Aerospace and Defense (part 
of United Technologies Aerospace Systems (UTAS)). Horizon further 
asserted that

[[Page 6750]]

the FAA did not justify the proposed requirement to return failed APDs 
to Kidde Aerospace and Defense or explain how this would improve the 
level of safety.
    The FAA does not agree that the requirement to return failed APDs 
to Kidde Aerospace and Defense places an unnecessary cost and 
regulatory burden on operators. Bombardier Service Bulletin 84-26-19, 
Revision `A,' dated February 11, 2019, refers to Kidde Aerospace and 
Defense Service Bulletin 10-1096-26-511, Paragraph 3.3.F, which 
specifies returning the part with a Return Authorization form to Kidde 
Aerospace and Defense so that operators can receive a free-of-charge 
replacement. The cost of an APD varies from $6,300 to $9,300, depending 
on the type. With seven APDs on the aircraft, it is actually a cost 
benefit to return failed APDs to obtain replacements free of charge. In 
addition, when an unsafe condition involves an escape in a 
manufacturer's quality control (QC) system, returning failed parts or 
reporting certain findings can be instrumental in determining the 
extent and nature of the QC problem, especially in cases where the data 
may not be available through other established means. The information 
collected from the return of the failed APDs is necessary to ensure 
that proper corrective action will be taken. The FAA has not changed 
this AD regarding this issue.

Additional Change to Proposed AD

    Paragraph (j) of the proposed AD (``Parts Installation 
Limitation'') would allow installation of an affected APD if it is 
successfully tested and reidentified in accordance with Bombardier 
Service Bulletin 84-26-19, Revision `A,' dated February 11, 2019. We 
have revised paragraph (j) in this AD to also allow installation of an 
affected APD that is tested and reidentified in accordance with 
Bombardier Service Bulletin 84-26-19, dated October 24, 2018.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule with the changes described previously 
and minor editorial changes. The FAA has 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.
    The FAA also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    Bombardier issued Service Bulletin 84-26-19, Revision `A,' dated 
February 11, 2019. This service information describes procedures for 
identification and testing, and reidentification or replacement if 
necessary, of affected APDs. 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

    The FAA estimates that this AD affects 65 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
             Labor cost                  Parts cost        Cost per product          Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Up to 10 work-hours x $85 per hour =              $0   Up to $850.............  Up to $55,250.
 Up to $850.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

                Estimated Costs of On-Condition Actions *
------------------------------------------------------------------------
          Labor cost              Parts cost        Cost per product
------------------------------------------------------------------------
Up to 124 work-hours x $85     Up to $51,076..  Up to $61,616.
 per hour = Up to $10,540.
------------------------------------------------------------------------
* The FAA has received no definitive data to provide cost estimates for
  the on-condition return of parts, except the FAA estimates that it
  would take about 1 work-hour per product to comply with the associated
  paperwork necessary for the return of parts.

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the cost estimate.

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 
Information Collection Clearance Officer, Federal Aviation 
Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

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.

[[Page 6751]]

    The FAA is 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
