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 ADDRESSES. Include ``Docket No. FAA-2022-0022; Project Identifier 
AD-2020-01264-A'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, 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 proposal 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 agency will also post a report summarizing each 
substantive verbal contact received about the NPRM.

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

[[Page 8753]]

responsive to the 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 the NPRM. Submissions containing CBI should be 
sent to John Marshall, Aviation Safety Engineer, Atlanta ACO Branch, 
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

    The FAA issued an NPRM (87 FR 6089, February 3, 2022) that would 
apply to certain serial-numbered Piper Model PA-34-200 airplanes. The 
NPRM proposed to require establishing a 500-hour life limit for bolt P/
N 693-215 and P/N NAS6207-50D. The NPRM was prompted by the 
determination that the life limit for these bolts, which are alternate 
bolts that attach the drag link to the nose gear, were not listed as 
airworthiness limitations. If the bolts remain in service beyond their 
fatigue life, failure of the nose landing gear could occur, which could 
result in loss of airplane control during take-off, landing, or taxi 
operations.

Need for the Correction

    As published, the docket number referenced throughout the NPRM is 
incorrect. The NPRM incorrectly references ``Docket No. FAA-2022-0222'' 
instead of ``Docket No. FAA-2022-0022.''
    Although no other part of the preamble or regulatory information 
has been corrected, for clarity, the FAA is publishing the entire 
proposed rule in the Federal Register.
    The comment due date of the NPRM remains March 21, 2022.

Related Service Information

    The FAA reviewed Piper Seneca Service Manual, Airworthiness 
Limitations, 753-817, page 1-1, dated November 30, 2019. This service 
information specifies the life limits of the P/N 693-215 (standard P/N 
NAS6207-50D) bolt that attaches the drag link to the nose gear 
trunnion.

ADs Mandating Airworthiness Limitations

    The FAA has previously mandated airworthiness limitations by 
issuing ADs that require revising the ALS of the existing maintenance 
manual or instructions for continued airworthiness to incorporate new 
or revised inspections and life limits. This AD, however, requires 
incorporating new or revised inspections and life limits into the 
maintenance records required by 14 CFR 91.417(a)(2) or 135.439(a)(2) 
for your airplane. The FAA does not intend this as a substantive 
change. Requiring incorporation of the new ALS requirements into the 
maintenance records, rather than requiring individual repetitive 
inspections and replacements, allows operators to record AD compliance 
once after updating the maintenance records, rather than recording 
compliance after every inspection and part replacement.

Proposed AD Requirements in This NPRM

    This proposed AD would require establishing a 500-hour life limit 
for bolt P/N 693-215 and P/N NAS6207-50D.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 187 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

Correction

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Corrected]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Piper Aircraft, Inc.: Docket No. FAA-2022-0022; Project Identifier 
AD-2020-01264-A.

[[Page 8754]]

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by April 4, 2022.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Piper Aircraft, Inc., Model PA-34-200 
airplanes, serial numbers 34-7250001 through 34-7450220, 
certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC) Code 3220, Nose/Tail 
Landing Gear.

(e) Unsafe Condition

    This AD was prompted by the determination that the life limit 
for alternate bolts that attach the drag link to the nose gear were 
not included as airworthiness limitations. The FAA is issuing this 
AD to establish a life limit on bolt part numbers 693-215 and 
NAS6207-50D that attach the drag link to the nose gear trunnion. The 
unsafe condition, if not addressed, could result in failure of the 
nose landing gear and lead to loss of airplane control during take-
off, landing, or taxi operations.

(f) Compliance

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

(g) Actions

    (1) Within 90 days after the effective date of this AD, 
incorporate into the maintenance records required by 14 CFR 
91.417(a)(2) or 135.439(a)(2) for your airplane a life limit of 500 
hours for bolt part numbers 693-215 and NAS6207-50D.
    Note to paragraph (g)(1): Piper Seneca Service Manual, 
Airworthiness Limitations, 753-817, page 1-1, dated November 30, 
2019, contains the life limit in paragraph (g)(1) of this AD.
    (2) Thereafter, except as provided in paragraph (h)(1) of this 
AD, no alternative replacement times may be approved for these 
bolts.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta ACO 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, send your request 
to your principal inspector or local Flight Standards District 
Office, as appropriate. If sending information directly to the 
manager of the certification office, send it to the attention of the 
person identified in paragraph (i)(1) of this AD.
    (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.
