SUPPLEMENTARY INFORMATION: Discussion Transport Canada, which is the aviation authority for Canada, has issued AD No. CF–2019–39, dated October 31, 2019 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for Diamond Aircraft Industries Models DA 40, DA 40 D, DA PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 40 F, and DA 40 NG airplanes. The MCAI states: Diamond Aircraft Industries (DAI) has received reports of fuel tank connection hose deterioration on the DA 40 aeroplanes. In a number of cases, rubber parts from the hoses were found in the fuel tank and gascolator. Investigation determined that the affected connection hoses originated from two isolated batches. Some of the affected hoses were installed on aeroplanes during production, while others were sold as replacement parts. Deterioration of fuel tank connection hoses, if not corrected, could result in contamination of the fuel system and restriction of fuel flow, leading to fuel starvation and reduced control of the aeroplane. To address this unsafe condition, DAI issued Mandatory Service Bulletins (MSBs) to provide instructions for identifying and replacing the affected parts. The MSBs also provide instructions to inspect the fuel tank chambers and remove rubber parts that have detached from the hoses. This AD mandates replacement of the affected parts, associated inspections and corrective actions detailed in the MSBs. You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0644. Related Service Information Under 1 CFR Part 51 The FAA reviewed the following Diamond Aircraft Industries Mandatory Service Bulletins: MSB 40–087, Revision 3, dated November 5, 2019, for the Model DA 40 airplanes; MSB F4– 037, Revision 3, dated November 5, 2019, for the Model DA 40 F airplanes; and MSB 40NG–064, Revision 2, dated August 29, 2019, for the Model DA 40 NG airplanes. The FAA also reviewed the following Diamond Aircraft Industries Work Instructions: WI–MSB 40–087, Revision 0, dated July 1, 2019, for the Model DA 40 airplanes; WI–MSB F4–037, Revision 0, dated July 1, 2019, for the Model DA 40 F airplanes; and WI–MSB 40NG–064, Revision 0, dated July 1, 2019, for the Model DA 40 NG airplanes. In combination for the applicable model airplane, the service bulletins and work instructions contain procedures for identifying and replacing affected parts, inspecting the fuel tank chambers, and removing rubber material that has detached from the hoses.

(2) Will not affect intrastate aviation in Alaska. FAA’s Determination and Requirements of the 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this AD because the FAA evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance The FAA estimates that this AD will affect 737 products of U.S. registry. The FAA also estimates that it would take about 16 work-hours per product to comply with the requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $48 per product. Based on these figures, the FAA estimates the cost of the AD on U.S. operators to be $1,408 per airplane, or $1,037,696 for the U.S. fleet. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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. 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. ■ Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. (d) Subject Air Transport Association of America (ATA) Code 28: Fuel System. khammond on DSKJM1Z7X2PROD with RULES FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because deterioration of fuel tank connection hoses could result in contamination of the fuel system and restriction of fuel flow, resulting in fuel starvation and reduced control of the airplane. Additionally, the compliance time for the required actions is shorter than the time necessary for the public to comment and for publication of the final rule. Therefore, the FAA finds good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and the FAA did not precede it by notice and opportunity for public comment. The FAA invites you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2020–0644; Product Identifier 2019–CE–057–AD’’ at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this AD. The FAA will consider all comments received by the closing date and may amend this AD because of those comments. The FAA will post all comments it receives, without change, to https:// www.regulations.gov, including any personal information you provide. The FAA will also post a report VerDate Sep<11>2014 15:52 Jul 14, 2020 Jkt 250001 Regulatory Findings The FAA determined that this proposed AD will not have federalism implications under Executive Order 13132.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada, which is the aviation authority for Canada, has 
issued AD No. CF-2019-39, dated October 31, 2019 (referred to after 
this as ``the MCAI''), to correct an unsafe condition for Diamond 
Aircraft Industries Models DA 40, DA 40 D, DA 40 F, and DA 40 NG 
airplanes. The MCAI states:

    Diamond Aircraft Industries (DAI) has received reports of fuel 
tank connection hose deterioration on the DA 40 aeroplanes. In a 
number of cases, rubber parts from the hoses were found in the fuel 
tank and gascolator. Investigation determined that the affected 
connection hoses originated from two isolated batches. Some of the 
affected hoses were installed on aeroplanes during production, while 
others were sold as replacement parts.
    Deterioration of fuel tank connection hoses, if not corrected, 
could result in contamination of the fuel system and restriction of 
fuel flow, leading to fuel starvation and reduced control of the 
aeroplane.
    To address this unsafe condition, DAI issued Mandatory Service 
Bulletins (MSBs) to provide instructions for identifying and 
replacing the affected parts. The MSBs also provide instructions to 
inspect the fuel tank chambers and remove rubber parts that have 
detached from the hoses. This AD mandates replacement of the 
affected parts, associated inspections and corrective actions 
detailed in the MSBs.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
deterioration of fuel tank connection hoses could result in 
contamination of the fuel system and restriction of fuel flow, 
resulting in fuel starvation and reduced control of the airplane. 
Additionally, the compliance time for the required actions is shorter 
than the time necessary for the public to comment and for publication 
of the final rule. Therefore, the FAA finds good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reasons stated above, the FAA finds that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not precede it by notice and opportunity for 
public comment. The FAA invites you to send any written relevant data, 
views, or arguments about this AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2020-0644; 
Product Identifier 2019-CE-057-AD'' at the beginning of your comments. 
The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. The FAA will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    The FAA will post all comments it receives, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact it receives about this AD.

Costs of Compliance

    The FAA estimates that this AD will affect 737 products of U.S. 
registry. The FAA also estimates that it would take about 16 work-hours 
per product to comply with the requirements of this AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $48 
per product.
    Based on these figures, the FAA estimates the cost of the AD on 
U.S. operators to be $1,408 per airplane, or $1,037,696 for the U.S. 
fleet.

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.
    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.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

Regulatory Findings

    The FAA determined that this proposed 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, and
    (2) Will not affect intrastate aviation in Alaska.
