SUPPLEMENTARY INFORMATION:
Background
The FAA is adopting a new AD for certain serial-numbered Robinson
Helicopter Company Model R22 BETA, R44, and R44 II helicopters. This AD
was prompted by reports of intermittent or abnormal operation of the
governor. In normal conditions, a properly functioning governor
maintains engine speed within acceptable limits. Intermittent or
abnormal operation of the governor may result in engine overspeed or
underspeed conditions during flight. If the engine governor
malfunctions, the pilot may assume manual throttle control by firmly
gripping the throttle and overriding the governor's friction clutch, or
by switching the governor off. In the event of low rotor RPM, an alarm
sounds. This condition, if not addressed, could result in reduced
control of the helicopter and subsequent emergency landing or loss of
control of the helicopter. The FAA is issuing this AD to address the
unsafe condition on these products.
FAA's Determination
The FAA is issuing this AD because the agency has determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type designs.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Robinson R22-series Governor & Engine RPM Sensor
Connector Upgrade Kit Instructions, KI-288 Revision A, and Robinson
R44-series Governor & Engine RPM Sensor Connector Upgrade Kit
Instructions, KI-287 Revision A, each dated February 23, 2022. This
service information specifies procedures to inspect the engine RPM
sensor wiring for damage, repair that wiring, and modify the governor
wiring connection to the airframe harness with different connectors for
improved clearance and strain relief.
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 ADDRESSES.
Other Related Service Information
The FAA reviewed Robinson Helicopter Company R22 Service Bulletin
SB-119, and Robinson Helicopter Company R44 Service Bulletin SB-111,
each dated February 23, 2022. This service information specifies
inspecting the sensor wiring, installing a governor wiring kit, and
accomplishing the starting engine and run-up checklist to verify proper
governor operation.
AD Requirements
This AD requires inspecting the engine RPM sensor wiring for
damage, and depending on the outcome, accomplishing repairs. This AD
also requires modifying the governor wiring connection to the airframe
harness by installing wiring kit KI-288 for Model R22 BETA helicopters
and wiring kit KI-287 for Model R44 and R44 II helicopters.
Interim Action
The FAA considers this AD to be an interim action as the design
approval
[[Page 35891]]
holder continues to investigate the unsafe condition identified in this
AD. If final action is later identified, the FAA might consider further
rulemaking then.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) 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 providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
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 foregoing notice and comment prior to adoption of this rule
because the next predicted event of intermittent or abnormal operation
of a governor is within three months. In light of this, the required
actions must be accomplished within 15 hours time-in-service or 15
days, whichever occurs first. This compliance time is shorter than the
time necessary for the public to comment and for publication of the
final rule. Accordingly, notice and opportunity for prior public
comment are impracticable and contrary to the public interest pursuant
to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forego notice and
comment.
Comments Invited
The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-2022-0676 and Project Identifier
AD-2022-00533-R'' at the beginning of your comments. The most helpful
comments reference a specific portion of the final rule, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this final rule 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
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this final rule.
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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Jeffrey
Chang, Aerospace Engineer, Propulsion Section, Los Angeles ACO Branch,
Compliance & Airworthiness Division, FAA, 3960 Paramount Blvd.,
Lakewood, CA 90712; telephone (562) 627-5263; email
<a href="/cdn-cgi/l/email-protection#0d67686b6b7f6874236e656c636a4d6b6c6c236a627b"><span class="__cf_email__" data-cfemail="305a5556564255491e5358515e57705651511e575f46">[email protected]</span></a>. Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.
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 FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 43 helicopters (4 Model R22
BETA helicopters and 39 Model R44 and R44 II helicopters) of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on
these numbers, the FAA estimates the following costs to comply with
this AD.
Inspecting the wiring and installing wiring kit KI-288 for Model
R22 BETA helicopters takes about 3.5 work-hours and parts cost about
$75 for an estimated cost of $373 per helicopter and $1,492 for the
U.S. fleet (4 Model R22 BETA helicopters).
Inspecting the wiring and installing wiring kit KI-287 for Model
R44 and R44 II helicopters takes about 4.5 work-hours and parts cost
about $125 for an estimated cost of $508 per helicopter and $19,812 for
the U.S. fleet (39 Model R44 and R44 II helicopters).
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
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, and
(2) Will not affect intrastate aviation in Alaska.
