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)
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.

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
The FAA received no comments on the NPRM or on the determination of
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.
The FAA estimates the following costs to comply with this AD:
|Determine material of the seat
belt center bracket
||0.25 work-hour x $85 per hour
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:
|Replace any non-steel seat belt
||0.75 work-hour x $85 per hour
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.
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
(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.
