Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2023-09-04, which applies to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, and certain Model 737-8 and -9 airplanes. AD 2023-09-04 requires inspecting all escape slide assemblies to identify affected parts and replacing affected escape slide assemblies with different assemblies. Since the FAA issued AD 2023-09-04, it was determined that additional airplanes might be affected by the unsafe condition. This proposed AD would retain the requirements of AD 2023-09-04 and require those actions for additional airplanes, including Model 737-8200 airplanes. The FAA is proposing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2023-09-04, which applies to certain The Boeing Company Model 737-600,
-700, -700C, -800, -900, and -900ER series airplanes, and certain Model
737-8 and -9 airplanes. AD 2023-09-04 requires inspecting all escape
slide assemblies to identify affected parts and replacing affected
escape slide assemblies with different assemblies. Since the FAA issued
AD 2023-09-04, it was determined that additional airplanes might be
affected by the unsafe condition. This proposed AD would retain the
requirements of AD 2023-09-04 and require those actions for additional
airplanes, including Model 737-8200 airplanes. The FAA is proposing
this AD to address the unsafe condition on these products.

Background
The FAA issued AD 2023-09-04, Amendment 39-22427 (88 FR 33817, May
25, 2023) (AD 2023-09-04), for certain The Boeing Company Model 737-
600, -700, -700C, -800, -900, and -900ER series airplanes, and certain
Model 737-8 and -9 airplanes. AD 2023-09-04 was prompted by reports of
uncommanded escape slide deployments in the passenger compartment while
the airplane was on the ground, caused by too much tension in the
inflation cable (introduced during packing of the slide) and the
movement of the escape slide assembly in the escape slide compartment
during normal airplane operations. AD 2023-09-04 requires inspecting
all escape slide assemblies to identify affected parts and replacing
affected escape slide assemblies with different assemblies. The agency
issued AD 2023-09-04 to address inflation of the escape slide while it
is in the escape slide compartment, which could result in injury to
passengers and crew during normal operation or impede an emergency
evacuation by rendering the exit unusable.
Actions Since AD 2023-09-04 Was Issued
Since the FAA issued AD 2023-09-04, the FAA determined that
additional airplanes might be affected by the unsafe condition. AD
2023-09-04 applies to airplanes identified by line number in Boeing
Special Attention Requirements Bulletin 737-25-1855 RB, Revision 1,
dated April 13, 2022; and Boeing Special Attention Requirements
Bulletin 737-25-1866 RB, Revision 1, dated April 11, 2022. However, the
FAA has determined that additional line-numbered airplanes, as well as
Model 737-8200 airplanes, might have an affected escape slide assembly
installed because the part is rotable. Since the affected parts are
rotable, they could later be installed on airplanes that were initially
delivered with acceptable parts, thereby creating an unsafe condition
in those airplanes.
In addition, Boeing issued Special Attention Requirements Bulletin
737-25-1866 RB, Revision 2, dated July 19, 2024, to revise the
applicable airplanes in the effectivity paragraph of Boeing Special
Attention Requirements Bulletin 737-25-1866 RB, Revision 1, dated April
11, 2022.
The FAA proposes to retain the requirements of AD 2023-09-04 and
also require that all Model 737-600, -700, -700C, -800, -900, and -
900ER series airplanes and Model 737-8, 737-9, and 737-8200 airplanes
that are excluded from the applicability of AD 2023-09-04 inspect all
escape slide assemblies to identify affected parts and accomplish
applicable on-condition actions. The FAA has determined that these
actions can be accomplished using Boeing Special Attention Requirements
Bulletin 737-25-1855 RB, Revision 1, dated April 13, 2022 (for all
Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes);
and Boeing Special Attention Requirements Bulletin 737-25-1866 RB,
Revision 1, dated April 11, 2022 (for all Model 737-8, 737-9, and 737-
8200 airplanes), regardless of whether the airplane model or line
number is identified in those bulletins.
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.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Boeing Special Attention Requirements Bulletin
737-25-1866 RB, Revision 2, dated July 19, 2024. This material
specifies procedures for inspecting all escape slide assemblies to
identify any escape slide assembly having part number (P/N) 5A3307-7
and replacing it with an assembly having P/N 5A3307-9 or P/N 5A3307-
701. Escape slide assembly P/N 5A3307-701 is one on which a firing
cable retention has been modified and the assembly reidentified with a
new part number.
This proposed AD would also require Boeing Special Attention
Requirements Bulletin 737-25-1855 RB, Revision 1, dated April 13, 2022;
and Boeing Special Attention Requirements Bulletin 737-25-1866 RB,
Revision 1, dated April 11, 2022, which the Director of the Federal
Register approved for incorporation by reference as of June 29, 2023
(88 FR 33817, May 25, 2023).
This material 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.
Proposed AD Requirements in This NPRM
This proposed AD would retain all requirements of AD 2023-09-04.
This proposed AD would also require those same actions for additional
airplanes. For information on the procedures and compliance times, see
this material at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2025-0481.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 2,666 airplanes of U.S. registry. The FAA estimates the
following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection or maintenance records 2 work-hours x $85 $0 $170 $425,340 (2,502
review (retained action from AD per hour = $170. airplanes).
2023-09-04).
Inspection or maintenance records 2 work-hours x $85 0 170 $27,880 (164
review (new proposed action). per hour = $170. airplanes).
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any replacements that
would be required based on the results of the proposed inspection. The
agency has no way of determining the number of aircraft that might need
these replacements:
[[Page 15323]]
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement.......................... Up to 1 work hour x $85 Up to $19,000.......... Up to $19,085 per
per hour = up to $85. escape slide assembly.
----------------------------------------------------------------------------------------------------------------
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.
