Airworthiness Directives; DAHER AEROSPACE (Type Certificate 
Previously Held by SOCATA) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain DAHER AEROSPACE (type certificate previously held by 
SOCATA) Model TBM 700 airplanes. This proposed AD was prompted by 
mandatory continuing airworthiness information (MCAI) issued by the 
aviation authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI identifies the unsafe 
condition as interference between the emergency exit trim panel and the 
upholstery panel, which could result in additional effort required to 
open the emergency exit door. This proposed AD would require 
modification of the gripping strap, which maintains the upholstery 
panel on the emergency exit trim panel. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this NPRM by April 24, 2023.

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 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

[[Page 14302]]

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 NPRM. Submissions containing CBI should be sent to Fred 
Guerin, Aviation Safety Engineer, General Aviation & Rotorcraft 
Section, International Validation Branch, FAA, 2300 S. 216th Street,

specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2022-0149, dated July 21, 2022 (referred to after this as ``the 
MCAI''), to correct an unsafe condition on certain serial-numbered 
DAHER AEROSPACE (type certificate previously held by SOCATA) Model TBM 
700 airplanes.
    The MCAI was prompted by a report that, due to interference between 
the emergency exit trim panel and the upholstery panel, additional 
effort may be required to open the emergency exit door. An 
investigation revealed that the gripping strap, which maintains the 
upholstery panel on the emergency exit trim panel, is not properly 
sized. The MCAI requires inserting a temporary revision (TR) into the 
emergency procedures section of the applicable pilot's operating 
handbook (POH), informing all flight crews, operating the airplane 
accordingly, and modifying the gripping strap, at which time the TR can 
be removed from the POH. The unsafe condition, if not addressed, could 
lead to failure of the emergency exit door to perform its intended 
function during an emergency opening, possibly resulting in reduced 
evacuation capacity from the airplane and injury to occupants.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0425.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Daher Aerospace Service Bulletin SB 70-304-25, 
dated July 2022, which specifies procedures for modifying the gripping 
strap on the emergency exit trim panel.
    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.

FAA's Determination

    These products have been approved by the aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI and service information described above. 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.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the MCAI, except as discussed under ``Differences Between this 
Proposed AD and the MCAI.''

Differences Between This Proposed AD and the MCAI

    The MCAI requires inserting a TR into the emergency procedures 
section of the applicable POH, informing all flight crews, and 
thereafter, operating the airplane accordingly until the modification 
of the gripping strap, at which time the TR can be removed from the 
POH. This proposed AD would only require modifying the gripping strap 
because FAA regulations mandate compliance with only the operating 
limitations section of the POH and not the emergency procedures 
section.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 841 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD:

----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Modification of the gripping strap....  1 work-hour x $85 per               $300            $385        $323,785
                                         hour = $85.
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 
proposed 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

    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.

Service Bulletin SB 70-304-25, dated July 2022 (Daher SB 70-304-25), 
except where Daher SB 70-304-25 specifies to discard certain parts, 
this AD requires removing those parts from service. If the 
operational check of the emergency exit fails, before further 
flight, re-modify the gripping strap on the emergency exit trim 
panel by following, as applicable for your serial-numbered airplane, 
sections A, B, and C in the Description of Accomplishment 
Instructions in Daher SB 70-304-25 until it passes this operational 
check, except where Daher SB 70-304-25 specifies to discard certain 
parts, this AD requires removing those parts from service.
