RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2018-26-03, which applies to all The Boeing Company Model 757-200
series airplanes. AD 2018-26-03 requires, for the Captain's and First
Officer's seats, repetitive horizontal actuator identifications,
repetitive checks of the horizontal movement system (HMS), a detailed
inspection of the HMS, as applicable, and applicable on-condition
actions. AD 2018-26-03 also requires a general visual inspection to
determine the seat part numbers of the Captain's and First Officer's
seats, a cable adjustment check on seats with certain seat part
numbers, and applicable on-condition actions. Since the FAA issued AD
2018-26-03, the FAA has determined that additional seats are affected
by the unsafe condition. This proposed AD would retain the actions
required by AD 2018-26-03 and add an inspection for previously omitted
part numbers. The FAA is proposing this AD to address the unsafe
condition on these products.

rulemaking.
Background
The FAA issued AD 2018-26-03, Amendment 39-19533 (83 FR 66612,
December 27, 2018) (AD 2018-26-03), for all The Boeing Company Model
757-200 series airplanes. AD 2018-26-03 was prompted by reports of
uncommanded movement of the Captain's and First Officer's seats. AD
2018-26-03 requires, for the Captain's and First Officer's seats,
repetitive horizontal actuator identifications, repetitive checks of
the HMS, a detailed inspection of the HMS, as applicable, and
applicable on-condition actions. AD 2018-26-03 also requires a general
visual inspection to determine the seat part numbers of the Captain's
and First Officer's seats, a cable adjustment check on seats with
certain seat part numbers, and applicable on-condition actions. The
agency issued AD 2018-26-03 to address uncommanded movement of the
Captain's and First Officer's seat, which could lead to reduced
controllability of the airplane.
Actions Since AD 2018-26-03 Was Issued
Since the FAA issued AD 2018-26-03, Boeing and the seat supplier
(Ipeco) determined that certain seat part numbers were inadvertently
omitted from the service information required by AD 2018-26-03. Ipeco
subsequently updated their service information to include the
additional part numbers, and Boeing updated their service information
as well. Based on this, the FAA has determined that additional seats
are affected by the unsafe condition.
In addition, the effectivity of Boeing Special Attention Service
Bulletin 757-25-0308, Revision 2, dated June 12, 2023; and Boeing
Special Attention Service Bulletin 757-25-0309, Revision 2, dated June
12, 2023; are limited to The Boeing Company Model 757-200 series
airplanes having certain line numbers. However, the applicability of
this proposed AD includes all The Boeing Company Model 757-200 series
airplanes. Because the affected parts are rotable parts, the FAA has
determined that these parts could later be installed on airplanes that
were initially delivered with acceptable parts, thereby subjecting
those airplanes to the unsafe condition.
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 Service Bulletin 757-25-
0308, Revision 2, dated June 12, 2023. This material specifies
procedures for repetitive horizontal actuator identifications,
repetitive checks of the HMS, a detailed inspection of the HMS, as
applicable, and applicable on-condition actions including an overhaul
and checks of the HMS, with the option to install a serviceable seat
under certain conditions, which terminates the repetitive checks.
The FAA reviewed Boeing Special Attention Service Bulletin 757-25-
0309, Revision 2, dated June 12, 2023. This material specifies
procedures for a general visual inspection to determine the seat part
numbers on the Captain's and First Officer's seats, and, for seats with
certain part numbers, a manual override cable adjustment check of the
Captain's and First Officer's seats, and applicable on-condition
actions including moving the adjustment nut, tightening the lock nut,
and readjusting the control lever.
This proposed AD would also require Boeing Special Attention
Service Bulletin 757-25-0308, Revision 1, dated June 7, 2018, which the
Director of the Federal Register approved for incorporation by
reference as of January 31, 2019 (83 FR 66612, December 27, 2018).
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
Although this proposed AD does not explicitly restate the
requirements of AD 2018-26-03, this proposed AD would retain all of the
requirements of AD 2018-26-03. Those requirements are referenced in the
material identified previously, which, in turn, is referenced in
paragraphs (g) and (h) of this proposed AD.
This proposed AD would retain all of the requirements of AD 2018-
26-03 and add actions for certain airplanes. This proposed AD would
also require accomplishment of the actions identified as ``RC''
(required for compliance) in the Accomplishment Instructions of Boeing
Special Attention Service Bulletins 757-25-0308 and 757-25-0309, both
Revision 2, dated June 12, 2023, described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD. For information on the procedures and compliance times,
see this material at regulations.gov under Docket No. FAA-2025-0473.
Acceptable Methods of Compliance
The FAA has determined that the actions required by paragraphs (g)
and (h) of this proposed AD are not required under specific conditions,
e.g., if it can be shown through maintenance records that the required
actions have already been accomplished by the previous revision of the
service information and specific conditions have been met. Table 1 to
paragraph (j) of this proposed AD identifies these conditions.
Complying with these conditions adequately addresses the unsafe
[[Page 14215]]
condition identified in this proposed AD.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 484 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Identification/check (retained Up to 11 work-hours $4,820 $5,755 per $2,785,420 per
actions from AD 2018-26-03). x $85 per hour = identification/ identification/
$935 per check cycle. check cycle.

Part identification (new proposed 1 work-hour x $85 0 $85................ $41,140.
action). per hour = $85.
----------------------------------------------------------------------------------------------------------------
Certain configurations of the Captain's and First Officer's seats
may require special tooling to test the seats. Special tooling for one
set of Captain's and First Officer's seats will cost $30,000, and a
certain other set will cost $32,500. If an operator owns both
combinations of seats, the special tooling will cost up to $62,500 per
operator.
We have received no definitive data that would enable us to provide
the remaining cost estimates for the on-condition actions specified in
this AD.
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 has 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 that the 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.
