Submissions containing CBI should be sent to Tuan Tran, Aviation Safety Engineer, FAA, 1701 Columbia Avenue, College Park, GA 30337. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background On November 15, 2023, the FAA received a report that a bearing fell out of a control column mount during routine handling, prior to installation on a Piper Model PA–46–600TP airplane. To conform to the type design, this bearing is installed in the mount block using a retaining compound into a recess in the control column mount with secondary retention provided by a retaining ring. Piper’s investigation into this incident revealed that the retaining ring was not installed. If the bearing is not secure due to the absence of the retaining ring the quadrant assembly and shaft could migrate aft and separate from the firewall attachment, creating a free end on the affected control column. With a free end on the control column, combined with other factors, the aileron cables could become slack, resulting in loss of aileron control, and it could also bind the free operation of the elevator control system. Slack aileron cables and binding of the elevator controls would affect both the pilot and copilot controls. On November 17, 2023, further investigation by Piper into this situation found a quality escape issue on certain Piper Model PA–46–350P, PA–46– 500TP, and PA–46–600TP airplanes where the possibility exists that the retaining ring was not installed during production or retaining compound was not applied to the bearing. A missing retaining ring in a control column PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 mount, if not addressed, could lead to a major failure in the aileron quadrant assembly and result in loss of pitch and roll control of the airplane during flight with consequent loss of control of the airplane. 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 design. Related Service Information Under 1 CFR Part 51 The FAA reviewed Piper Service Bulletin No. 1409A, dated November 21, 2023 (Piper SB 1409A). This service information specifies procedures for inspecting the left and right control column mounts to determine if a retaining ring is installed, inspecting the bearing in the mount block for the presence of retaining compound, installing a retaining ring, and applying retaining compound to the bearing. 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. AD Requirements This AD requires accomplishing the actions identified as ‘‘RC’’ (required for compliance) in Part III. of the Instructions in Piper SB 1409A. 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 forgoing notice and comment prior to adoption of this rule because a missing retaining ring in a control column mount, if not addressed, could lead to a major failure E:\FR\FM\14DER1.SGM 14DER1 Federal Register / Vol. 88, No. 239 / Thursday, December 14, 2023 / Rules and Regulations in the aileron quadrant assembly without warning and result in loss of pitch and roll control of the airplane during flight with consequent loss of control of the airplane. Because this could happen without warning, the left and right control column mounts must be inspected before further flight to determine if the retaining ring is missing. 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 forgo notice and comment. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when 86573 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 57 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost 3 work-hours × $85 per hour = $255 ............ 16 work-hours × $85 per hour = $1,360 ....... Inspection of Model PA–46–350P airplanes Inspection of Model PA–46–500TP and Model PA–46–600TP airplanes. The FAA estimates the following costs to do any necessary actions that would be required based on the results of the inspection. The agency has no Cost per product $0 0 $255 1,360 Cost on U.S. operators $3,825 (15 airplanes). $57,120 (42 airplanes). way of determining the number of aircraft that might need these actions: ON-CONDITION COSTS Action Labor cost Installation of retaining ring .......................................... Application of retaining compound ............................... 0.50 work-hour × $85 per hour = $42.50 ..................... 0.50 work-hour × $85 per hour = $42.50 ..................... lotter on DSK11XQN23PROD with RULES1 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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 VerDate Sep<11>2014 16:17 Dec 13, 2023 Jkt 262001 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.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Piper Aircraft, Inc. (Piper) Model PA-46-350P, PA-46-500TP, and 
PA-46-600TP airplanes. This AD was prompted by a report that a bearing 
fell out of a control column mount during routine handling prior to 
installation in an affected airplane and the discovery that a quality 
escape condition could exist on other airplanes. This AD requires 
inspecting the left and right control column mounts to determine if a 
retaining ring is installed. If a retaining ring is not installed, this 
AD requires inspecting the bearing in the mount block for the presence 
of retaining compound, and depending on the inspection results, 
installing a retaining ring and applying retaining compound to the 
bearing, as applicable. The FAA is issuing this AD to address the 
unsafe condition on these products.

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 Tuan 
Tran, Aviation Safety Engineer, FAA, 1701 Columbia Avenue, College 
Park, GA 30337. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    On November 15, 2023, the FAA received a report that a bearing fell 
out of a control column mount during routine handling, prior to 
installation on a Piper Model PA-46-600TP airplane. To conform to the 
type design, this bearing is installed in the mount block using a 
retaining compound into a recess in the control column mount with 
secondary retention provided by a retaining ring. Piper's investigation 
into this incident revealed that the retaining ring was not installed. 
If the bearing is not secure due to the absence of the retaining ring 
the quadrant assembly and shaft could migrate aft and separate from the 
firewall attachment, creating a free end on the affected control 
column. With a free end on the control column, combined with other 
factors, the aileron cables could become slack, resulting in loss of 
aileron control, and it could also bind the free operation of the 
elevator control system. Slack aileron cables and binding of the 
elevator controls would affect both the pilot and copilot controls. On 
November 17, 2023, further investigation by Piper into this situation 
found a quality escape issue on certain Piper Model PA-46-350P, PA-46-
500TP, and PA-46-600TP airplanes where the possibility exists that the 
retaining ring was not installed during production or retaining 
compound was not applied to the bearing. A missing retaining ring in a 
control column mount, if not addressed, could lead to a major failure 
in the aileron quadrant assembly and result in loss of pitch and roll 
control of the airplane during flight with consequent loss of control 
of the airplane. 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 design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Piper Service Bulletin No. 1409A, dated November 
21, 2023 (Piper SB 1409A). This service information specifies 
procedures for inspecting the left and right control column mounts to 
determine if a retaining ring is installed, inspecting the bearing in 
the mount block for the presence of retaining compound, installing a 
retaining ring, and applying retaining compound to the bearing. 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.

AD Requirements

    This AD requires accomplishing the actions identified as ``RC'' 
(required for compliance) in Part III. of the Instructions in Piper SB 
1409A.

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 forgoing notice and comment prior to adoption of this rule 
because a missing retaining ring in a control column mount, if not 
addressed, could lead to a major failure

[[Page 86573]]

in the aileron quadrant assembly without warning and result in loss of 
pitch and roll control of the airplane during flight with consequent 
loss of control of the airplane. Because this could happen without 
warning, the left and right control column mounts must be inspected 
before further flight to determine if the retaining ring is missing. 
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 forgo notice and 
comment.

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

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                    Cost per

 and Model PA-46-600TP airplanes.  per hour = $1,360.
----------------------------------------------------------------------------------------------------------------

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

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

                                                 $42.50.
Application of retaining compound.............  0.50 work-hour x $85 per hour =               10           52.50

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

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected operators.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by

[[Page 86574]]

in an affected airplane and the discovery that a quality escape 
condition could exist on other airplanes. The FAA is issuing this AD 
to address a missing retaining ring in a control column mount. A 
missing retaining ring in a control column mount, if not addressed, 
could lead to a major failure in the aileron quadrant assembly and 
result in loss of pitch and roll control during flight with 
consequent loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Before further flight after the effective date of this AD, do 
all applicable actions identified as ``RC'' (required for 
compliance) in, and in accordance with Part III. of the Instructions 
in Piper Service Bulletin No. 1409A, dated November 21, 2023 (Piper 
SB 1409A).

(h) Special Flight Permit

    For airplanes with greater than 25 flight hours time since new, 
a one-time flight is allowed to reach the nearest facility that is 
capable of doing the inspection and repair described in Part III. of 
the Instructions in Piper SB 1409A, provided the flight is with 
minimum required crew and after verification of the integrity of the 
left and right control columns (the control columns do not feel or 
visually appear to be loose, do not have a substantial increase in 
control force requirements, or do not have a reduction in control 
authority).

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, East Certification Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,

and email to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local Flight Standards District Office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by the Piper Organization Designation 
Authorization (ODA) that has been authorized by the Manager, East 
Certification Branch to make those findings. To be approved, the 
repair method, modification deviation, or alteration deviation must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) Except as required by paragraph (g) of this AD: For service 
information that contains steps that are labeled as Required for 
Compliance (RC), the following provisions apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. An AMOC is required for any deviations to RC steps, 
including substeps and identified figures.
    (ii) The steps not labeled as RC may be deviated from using 
accepted methods in accordance with the operator's maintenance or 
inspection program without obtaining approval of an AMOC, provided 
the RC steps, including substeps and identified figures, can still 
be done as specified, and the airplane can be put back in an 
airworthy condition.
