SUPPLEMENTARY INFORMATION:

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not provide you with notice and an opportunity 
to provide your comments prior to it becoming effective. However, the 
FAA invites you to participate in this rulemaking by submitting written 
comments, data, or views. The most helpful comments reference a 
specific portion of the AD, explain the reason for any recommended 
change, and include supporting data. To ensure the docket does not 
contain duplicate comments, commenters should send only one copy of 
written comments, or if comments are filed electronically, commenters 
should submit them only one time.
    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 file in the docket all comments received, as well 
as a report summarizing each substantive public contact with FAA 
personnel concerning this rulemaking during the comment period. The FAA 
will consider all the comments received and may conduct additional 
rulemaking based on those comments.

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 final rule 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 final rule, 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 final rule. Submissions 
containing CBI should be sent to Daniel E. Moore, Aviation Safety 
Engineer, Regulations & Policy Section, Rotorcraft Standards Branch, 
FAA, 10101 Hillwood Pkwy., Fort Worth, TX 76177; telephone 817-222-
5110; email daniel.e.moore@faa.gov. Any commentary that the FAA 
receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Discussion

    Transport Canada, which is the aviation authority for Canada, has 
issued Canadian AD No. CF-2019-28, dated July 25, 2019, to correct an 
unsafe condition for Bell Model 505 helicopters, serial number 65011 
through 65211. Transport Canada advises of a report showing that a 
bearing migrated out of its inner ring. An investigation revealed that, 
although the inspection witness mark was applied to the part, the 
bearing had not been staked during manufacturing. Transport Canada 
further advises that an un-staked bearing, which has migrated out of 
its bore, may lead to restriction of the swashplate's movement as a 
result of contact or binding between the control tube clevis and the 
bearing housing.
    This contact or binding may restrict control authority and may also 
introduce unintended loads into the control system causing a failure of 
the control tube and/or bearing. This situation, if not corrected, 
could lead to loss of control of the helicopter. Accordingly, the 
Transport Canada AD

[[Page 59662]]

requires a one-time inspection of each bearing.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Canada and are approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with Canada, Transport Canada, its 
technical representative, has notified the FAA of the unsafe condition 
described in its AD. The FAA is issuing this AD after evaluating all of 
the information provided by Transport Canada and determining the unsafe 
condition exists and is likely to exist or develop on other helicopters 
of the same type design.

Related Service Information Under 1 CFR Part 51

    Bell has issued Alert Service Bulletin 505-19-13, dated July 2, 
2019, which specifies procedures for a one-time inspection of the 
staking of certain bearings.
    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

    Bell Helicopter has issued BHT-ALL-SPM Chapter 9--Bearings, 
Sleeves, and Bushings, Revision 7, dated March, 24, 2017, which 
specifies procedures for servicing swashplate assembly bearings, 
sleeves, and bushings.

AD Requirements

    This AD requires, within 20 hours time-in-service (TIS), using a 
10X or higher power magnifying glass, inspecting both sides of each 
affected bearing for staking in the outer ring part number (P/N) 206-
010-453, inner ring P/N 206-010-451, and lever assembly P/N 206-010-
447. If either side of a bearing is not staked, this AD requires 
removing the bearing from service before further flight.

Differences Between This AD and the Transport Canada AD

    The Transport Canada AD requires inspecting the bearings for proper 
staking, whereas this AD requires inspecting both sides of each bearing 
for staking instead. If a swashplate assembly bearing is not staked, 
the Transport Canada AD requires replacing the bearing and contacting 
Bell, whereas this AD requires removing the bearing from service 
instead.

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.

Costs of Compliance

    The FAA estimates that this AD affects 81 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates that operators may incur the following 
costs in order to comply with this AD.
    Inspecting the bearings for staking takes about one work-hour for 
an estimated cost of $85 per helicopter and $6,885 for the U.S. fleet. 
Replacing a bearing takes about one work-hour and parts cost about $100 
for an estimated cost of $185 per replacement.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C.) 
authorizes agencies to dispense with notice and comment procedures for 
rules when the agency, for ``good cause'' finds that those procedures 
are ``impracticable, unnecessary, or contrary to the public interest.'' 
Under this section, an agency, upon finding good cause, may issue a 
final rule without seeking comment prior to the rulemaking.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the required corrective action must be completed within 20 
hours TIS, a time period of up to one month based on the average 
flight-hour utilization rate of these helicopters. Therefore, notice 
and opportunity for prior public comment are impracticable and contrary 
to public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for 
the reasons stated above, the FAA finds that good cause exists pursuant 
to 5 U.S.C. 553(d) for making this amendment effective in less than one 
month.

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 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, 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.
