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.

DATES: The FAA must receive comments on this proposed AD by May 15, 
2025.

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

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

    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.

(n) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, AIR-520, Continued Operational Safety Branch, 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or 
responsible Flight Standards Office, as appropriate. If sending 
information directly to the manager of the certification office, 
send it to the attention of the person identified in paragraph (o) 
of this AD. Information may be emailed to [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the responsible Flight Standards Office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, AIR-
520, Continued Operational Safety Branch, FAA, to make those 
findings. To be approved, the repair method, modification deviation, 
or alteration deviation must meet the certification basis of the 
airplane, and the approval must specifically refer to this AD.
    (4) AMOCs approved for AD 2018-26-03 are approved as AMOCs for 
the corresponding provisions of this AD.
    (5) For material that contains steps that are labeled as 
Required for Compliance (RC), the provisions of paragraphs (n)(5)(i) 
and (ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
