[Docket No. FAA-2023-0425; Project Identifier MCAI-2022-00980-A]
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
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,
ADDRESSES: You may send comments, using the procedures found in

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-2023-0425; Project Identifier
MCAI-2022-00980-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
regulations.gov, including any personal information you provide. The
agency will also post a report summarizing each substantive verbal
contact received about this 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 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 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,
Des Moines, WA 98198. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
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
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.
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
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
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
||Cost per product
||Cost on U.S. operators
|Modification of the gripping
||1 work-hour x $85 per hour =
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.
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
(1) Is not a ``significant regulatory action'' under Executive
(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.
