Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2022-0014; Project Identifier AD-2021-00114-A; 
Amendment 39-22006; AD 2022-08-03]
RIN 2120-AA64


Airworthiness Directives; Textron Aviation Inc. (Type Certificate 
Previously Held by Cessna Aircraft Company) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Textron Aviation Inc. (type certificate previously held by 
Cessna Aircraft Company) (Textron) Model 120 and 140 airplanes and all 
Model 140A airplanes. This AD was prompted by reports of seat belt 
center bracket failures from overstress. This AD requires determining 
if the seat belt center bracket is made of steel and replacing any non-
steel brackets. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective May 17, 2022.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain serial-numbered 
Textron (type certificate previously held by Cessna Aircraft Company) 
Model 120 and 140 airplanes and all Model 140A airplanes. The NPRM 
published in the Federal Register on January 27, 2022 (87 FR 4168). The 
NPRM was prompted by reports of seat belt center bracket failures. 
Analysis of the failures determined the original aluminum seat belt 
center bracket does not have sufficient strength and can fail due to 
overstress during incidents and accidents. In the NPRM, the FAA 
proposed to require determining if the seat belt center bracket is made 
of steel and replacing any non-steel brackets. The FAA is issuing this 
AD to prevent failure of the seat belt center bracket, which could lead 
to failure of the seat belt restraint system and injury to occupants.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
requires adopting this AD as proposed. Accordingly, the FAA is issuing 
this AD to address the unsafe condition on these products. This AD is 
adopted as proposed in the NPRM.

Related Service Information

    The FAA reviewed Cessna Single Engine Service Bulletin SEB-25-03, 
dated February 17, 2015. This service information specifies the 
location of the affected seat belt center bracket. This service 
information also contains a figure depicting the location of the 
seatbelt center bracket.
    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.

Costs of Compliance

    The FAA estimates that this AD affects 2,033 airplanes of U.S. 
registry.
    The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs

             Action                    Labor cost              Parts cost            airplane        operators

                                   $21.25.
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary 
replacements that may be required. The agency has no way of determining 
the number of airplanes that might need these replacements:

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

List of Subjects in 14 CFR Part 39

seats is made of steel by placing a magnet on the center of the 
bracket. This action may be performed by the owner/operator (pilot) 
holding at least a private pilot certificate and must be entered 
into the aircraft records showing compliance with this AD in 
accordance with 14 CFR 43.9(a)(1) through (4) and 14 CFR 
91.417(a)(2)(v). The record must be maintained as required by 14 CFR 
91.417. This authority is not applicable to aircraft being operated 
under 14 CFR part 119.
    (i) If the seat belt center bracket is made of steel, no 
additional action is required.
    (ii) If the seat belt center bracket is not made of steel, 
within 12 months after the effective date of this AD, replace with a 
steel part number (P/N) 0425132 seat belt center bracket.
    (2) As of the effective date of this AD, do not install a seat 
belt center bracket P/N 0425132 that is not made of steel on any 
airplane.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Wichita 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
