(e) Unsafe Condition 

This AD was prompted by a failure of the 

dual ethernet communication channel on a 

dual-channel data concentration and 

processing unit, which triggered the opening 

of electronic circuit breakers that caused 

several unintended system activations. The 

FAA is issuing this AD to prevent failure of 

the dual ethernet communication channel on 

a dual-channel data concentration and 

processing unit. The unsafe condition, if not 

addressed, could result in increased pilot 

workload and reduced control of the 

airplane. 

(f) Compliance

CBI is commercial or financial 

information that is both customarily and 


khammond on DSKJM1Z7X2PROD with PROPOSALS
6090 Federal Register / Vol. 87, No. 23 / Thursday, February 3, 2022 / Proposed Rules 

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

be placed in the public docket for this 

rulemaking. 

Background 

Piper notified the FAA that prior 

revisions of the ALS for certain Piper 

Model PA–34–200 airplanes did not 

contain a life limit for bolt part number 

(P/N) 693–215 (standard P/N NAS6207– 

50D). Bolt P/N 693–215 (NAS6207–50D) 

is an alternate part for P/N 400–274 

(standard P/N AN7–35). These bolts 

attach the drag link to the nose gear 

trunnion on Piper Model PA–34–200 

airplanes. Piper did not include an ALS 

revision for the P/N 693–215 (standard 

P/N NAS6207–50D) bolt to establish the 

same life limit as the P/N 400–274 

(AN7–35). 

If bolt P/N 693–215 (standard P/N 

NAS6207–50D) that attaches the drag 

link to the nose gear trunnion remains 

in service beyond its 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. 

FAA’s Determination 

The FAA is issuing this NPRM after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type design. 

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: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

airplane 

Cost on U.S. 

operators 

Revise the Airworthiness Limitations ......... 1 work-hour × $85 per hour = $85 ............ Not Applicable ........ $85 $15,895 

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.

The Proposed Amendment 

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 

■ 1. The authority citation for part 39 

continues to read as follows: 

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

Federal Register / Vol. 87, No. 23 / Thursday, February 3, 2022 / Proposed Rules 6091 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

Piper Aircraft, Inc.: Docket No. FAA–2022– 

0222; Project Identifier AD–2020–01264– 

A. 

(a) Comments Due Date 

The FAA must receive comments on this 

airworthiness directive (AD) by March 21, 

2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Piper Aircraft, Inc.,

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 takeoff, 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

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/

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2021–17–18, which applies to all 

Leonardo S.p.a. Model A109C, A109K2, 

A109E, A109S, and AW109SP 

helicopters. AD 2021–17–18 requires an 

inspection of certain tail rotor (TR) 

sleeve assemblies for discrepancies, an 

inspection of certain TR shaft 

assemblies for discrepancies, a 

repetitive measurement of the position 

of the bushing of the TR sleeve assembly 

in relation to the pitch change slider 

assembly, and corrective actions if 

necessary. Since the FAA issued AD 

2021–17–18, the FAA has determined 

that it is necessary to require repetitive 

inspections of certain TR sleeve 

assemblies and corrective actions. This 

proposed AD would retain the 

requirements of AD 2021–17–18; and 

would also require repetitive 

inspections of the TR sleeve assemblies, 

and corrective actions if necessary, as 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference 

(IBR). The FAA is proposing this AD to 

address the unsafe condition on these 

products. 

DATES: The FAA must receive comments 

on this proposed AD by March 21, 2022. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
