(Textron) Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Textron (type certificate previously held by Cessna Aircraft Company) Models 208 and 208B airplanes. This proposed AD was prompted by reports of loose elevator torque tube attach fasteners. This proposed AD would require repetitively inspecting the inboard and outboard elevator torque tube attachments for loose or incorrectly installed fasteners, replacing all fasteners if loose or incorrectly installed fasteners are found, and reporting the inspection results to the FAA. This AD also includes optional actions to terminate the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2020–0811; Product Identifier 2019–CE–055–AD’’ at the beginning of your comments. The FAA will consider all comments received by E:\FR\FM\22SEP1.SGM 22SEP1 59458 Federal Register / Vol. 85, No. 184 / Tuesday, September 22, 2020 / Proposed Rules the closing date and may amend this NPRM because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, 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 proposed AD. airplanes. Textron identified a quality escape affecting certain serial-numbered Model 208 and 208B airplanes. Fastener holes in the inboard and outboard elevator torque tube connections may have been oversized and fasteners at the inboard and outboard torque tube connections may have been installed incorrectly. This condition, if not addressed, could result in failure of the elevator torque tube fasteners, leading to loss of elevator control and loss of controlled flight. Confidential Business Information Related Service Information Under 1 CFR Part 51 The FAA reviewed Task 27–30–00– 290, Left and Right Elevator Torque Tube Attach Points (Borescope) Special Detailed Inspection, dated October 1, 2018, of the Cessna Model 208 Maintenance Manual (Task 27–30–00– 290). This service information contains procedures for performing a detailed borescope inspection of the left and right elevator torque tube attach points. 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. Confidential Business Information (CBI) is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to Bobbie Kroetch, Aerospace Engineer, Wichita ACO Branch, FAA, 1801 Airport Road, Wichita, Kansas 67209. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Discussion The FAA received reports of loose elevator torque tube attach fasteners on low flight time Textron Model 208B Other Related Service Information The FAA also reviewed Textron Aviation Mandatory Caravan Service Bulletin CAB–27–06, dated October 14, 2019 (CAB–27–06). This service information contains instructions for visually inspecting the left and right elevator torque tube attach points for the presence of loose rivets and replacing loose or incorrectly installed rivets. FAA’s Determination The FAA is proposing this AD because it evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of this same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between this Proposed AD and the Service Information.’’ This proposed AD also requires reporting the inspection results to the FAA. Differences Between This Proposed AD and the Service Information Task 27–30–00–290 only specifies replacing loose fasteners. The proposed AD would require replacement of all 48 fasteners if any single inboard or outboard elevator torque tube attach fastener is found loose or incorrectly installed. The FAA determined based on field evidence that identification of one loose fastener often indicates other fasteners may be affected. CAB–27–06, which would not be incorporated by reference in this proposed AD, specifies performing an initial inspection within 800 flight hours or 12 months from date of receipt, whichever occurs first. This proposed AD would require an initial inspection before the airplane accumulates 800 hours time-in-service (TIS) or within 200 hours TIS after the AD effectivity date, whichever occurs later. CAB–27–06 also specifies, without sufficient data, that an inspection is not required for airplanes that have reached 4,000 hours. The FAA determined an inspection of high-time airplanes is necessary to verify whether these airplanes are affected. This proposed AD would require a one-time visual inspection for airplanes that have already accumulated 4,000 hours TIS. Costs of Compliance The FAA estimates that this proposed AD affects 232 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Inspection ....................... 1 work-hour × $85 per hour = $85 ... Not applicable ............... $85 per inspection cycle Reporting Requirement .. 1 work-hour × $85 per hour = $85 ... Not applicable ............... $85 per report ............... The FAA estimates the following costs to do any necessary replacements that would be required based on the VerDate Sep<11>2014 17:17 Sep 21, 2020 Jkt 250001 results of the proposed inspection. The FAA has no way of determining the PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 Cost on U.S. operators $19,720 per inspection cycle. $19,720 per report. number of airplanes that might need these replacements: E:\FR\FM\22SEP1.SGM 22SEP1 Federal Register / Vol. 85, No. 184 / Tuesday, September 22, 2020 / Proposed Rules 59459 ON-CONDITION COSTS Action Labor cost Fastener Replacement: All 48 Fasteners ..................... 16 work-hours × $85 per hour = $1,360 ...................... 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. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all costs in this 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 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 currently 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, searching existing data sources, gathering and maintaining the data needed, completing and reviewing the collection of information. All responses to this collection of information are mandatory. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden 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. 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 VerDate Sep<11>2014 17:17 Sep 21, 2020 Jkt 250001 that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings The FAA 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) 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.

verbal contact it receives about this proposed AD.

Confidential Business Information

    Confidential Business Information (CBI) is commercial or financial 
information that is both customarily and actually treated as private by 
its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), 
CBI is exempt from public disclosure. If your comments responsive to 
this NPRM contain commercial or financial information that is 
customarily treated as private, that you actually treat as private, and 
that is relevant or responsive to this NPRM, it is important that you 
clearly designate the submitted comments as CBI. Please mark each page 
of your submission containing CBI as ``PROPIN.'' The FAA will treat 
such marked submissions as confidential under the FOIA, and they will 
not be placed in the public docket of this NPRM. Submissions containing 
CBI should be sent to Bobbie Kroetch, Aerospace Engineer, Wichita ACO 
Branch, FAA, 1801 Airport Road, Wichita, Kansas 67209. Any commentary 
that the FAA receives which is not specifically designated as CBI will 
be placed in the public docket for this rulemaking.

Discussion

    The FAA received reports of loose elevator torque tube attach 
fasteners on low flight time Textron Model 208B airplanes. Textron 
identified a quality escape affecting certain serial-numbered Model 208 
and 208B airplanes. Fastener holes in the inboard and outboard elevator 
torque tube connections may have been oversized and fasteners at the 
inboard and outboard torque tube connections may have been installed 
incorrectly.
    This condition, if not addressed, could result in failure of the 
elevator torque tube fasteners, leading to loss of elevator control and 
loss of controlled flight.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Task 27-30-00-290, Left and Right Elevator Torque 
Tube Attach Points (Borescope) Special Detailed Inspection, dated 
October 1, 2018, of the Cessna Model 208 Maintenance Manual (Task 27-
30-00-290). This service information contains procedures for performing 
a detailed borescope inspection of the left and right elevator torque 
tube attach points. 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.

Other Related Service Information

    The FAA also reviewed Textron Aviation Mandatory Caravan Service 
Bulletin CAB-27-06, dated October 14, 2019 (CAB-27-06). This service 
information contains instructions for visually inspecting the left and 
right elevator torque tube attach points for the presence of loose 
rivets and replacing loose or incorrectly installed rivets.

FAA's Determination

    The FAA is proposing this AD because it evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of this same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.'' This proposed AD also requires reporting the inspection 
results to the FAA.

Differences Between This Proposed AD and the Service Information

    Task 27-30-00-290 only specifies replacing loose fasteners. The 
proposed AD would require replacement of all 48 fasteners if any single 
inboard or outboard elevator torque tube attach fastener is found loose 
or incorrectly installed. The FAA determined based on field evidence 
that identification of one loose fastener often indicates other 
fasteners may be affected.
    CAB-27-06, which would not be incorporated by reference in this 
proposed AD, specifies performing an initial inspection within 800 
flight hours or 12 months from date of receipt, whichever occurs first. 
This proposed AD would require an initial inspection before the 
airplane accumulates 800 hours time-in-service (TIS) or within 200 
hours TIS after the AD effectivity date, whichever occurs later.
    CAB-27-06 also specifies, without sufficient data, that an 
inspection is not required for airplanes that have reached 4,000 hours. 
The FAA determined an inspection of high-time airplanes is necessary to 
verify whether these airplanes are affected. This proposed AD would 
require a one-time visual inspection for airplanes that have already 
accumulated 4,000 hours TIS.

Costs of Compliance

    The FAA estimates that this proposed AD affects 232 airplanes of 
U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

                                                 Estimated Costs

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

    The FAA estimates the following costs to do any necessary 
replacements that would be required based on the results of the 
proposed inspection. The FAA has no way of determining the number of 
airplanes that might need these replacements:

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

    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. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all costs in 
this 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 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 currently 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, searching existing data sources, gathering and 
maintaining the data needed, completing and reviewing the collection of 
information. All responses to this collection of information are 
mandatory. Send comments regarding this burden estimate or any other 
aspect of this collection of information, including suggestions for 
reducing this burden 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.
    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 Findings

    The FAA 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) 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.
