Abstract

The FAA proposes to supersede Airworthiness Directive (AD) 2019-22-02, which applies to all The Boeing Company Model 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747-8F, and 747-8 series airplanes. AD 2019-22-02 was prompted by reports of uncommanded fore and aft movement of the Captain's and First Officer's seats. AD 2019-22-02 requires identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and applicable on-condition actions for affected seats. AD 2019- 22-02 also requires a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats, and applicable on-condition actions. AD 2019-22- 02 also provides an optional terminating action for the repetitive actions for certain seats. Since the FAA issued AD 2019-22-02, the FAA has determined that additional seats are affected by the unsafe condition. This proposed AD would retain the actions required by AD 2019-22-02 and adds an inspection of previously omitted part numbers. The FAA is proposing this AD to address the unsafe condition on these products.

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) 
2019-22-02, which applies to all The Boeing Company Model 747-200B, 
747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747-8F, and 
747-8 series airplanes. AD 2019-22-02 was prompted by reports of 
uncommanded fore and aft movement of the Captain's and First Officer's 
seats. AD 2019-22-02 requires identifying the part number, and the 
serial number if applicable, of the Captain's and First Officer's 
seats, and applicable on-condition actions for affected seats. AD 2019-
22-02 also requires a one-time detailed inspection and repetitive 
checks of the horizontal movement system (HMS) of the Captain's and 
First Officer's seats, and applicable on-condition actions. AD 2019-22-
02 also provides an optional terminating action for the repetitive 
actions for certain seats. Since the FAA issued AD 2019-22-02, the FAA 
has determined that additional seats are affected by the unsafe 
condition. This proposed AD would retain the actions required by AD 
2019-22-02 and adds an inspection of previously omitted part numbers. 
The FAA is proposing this AD to address the unsafe condition on these 
products.

Background

    The FAA issued AD 2019-22-02, Amendment 39-19781 (84 FR 67854, 
December 12, 2019) (AD 2019-22-02), for all The Boeing Company Model 
747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 
747-8F, and 747-8 series airplanes. AD 2019-22-02 was prompted by 
reports of uncommanded fore and aft movement of the Captain's and First 
Officer's seats. AD 2019-22-02 requires an identification of the part 
number, and if applicable the serial number, of the Captain's and First 
Officer's seats, and applicable on-condition actions. AD 2019-22-02 
also requires a one-time detailed inspection and repetitive checks of 
the HMS of the Captain's and First Officer's seats, and applicable on-
condition actions. AD 2019-22-02 also provides an optional terminating 
action for the repetitive checks of the HMS for certain airplanes. The 
FAA issued AD 2019-22-02 to address uncommanded fore and aft movement 
of the Captain's and First Officer's seats. An uncommanded fore or aft 
seat movement during a critical part of a flight, such as takeoff or 
landing, could cause a flight control obstruction or unintended flight 
control input, which could result in the loss of the ability to control 
the airplane.

Actions Since AD 2019-22-02 Was Issued

    Since the FAA issued AD 2019-22-02, Boeing and the seat supplier 
(Ipeco) determined that certain seat part numbers were inadvertently 
omitted from the service information required by AD 2019-22-02. 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.

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 747-25-
3644, Revision 2, dated January 27, 2023. The material describes 
procedures for identification of the part number, and the serial number 
if applicable, of the Captain's and First Officer's seats, and 
applicable on-condition actions. On-condition actions include an 
inspection of each seat's fore and aft and vertical manual control 
levers for looseness, installation of serviceable seats, and a seat 
operational test after any cable adjustment. This material also adds 
Ipeco seat part numbers 3A258-0041-01-1Z and 3A258-0042-01-1Z.
    The FAA also reviewed Boeing Special Attention Service Bulletin 
747-25-3653, Revision 2, dated January 27, 2023. This material 
describes procedures for a detailed inspection and repetitive checks of 
the HMS (including for any Artus part and amendment numbers of the 
horizontal actuator of the HMS) for the Captain's and First Officer's 
seats for findings (e.g., evidence of cracks, scores, corrosion, dents, 
deformation, or visible wear; and incorrectly assembled microswitch 
assemblies, actuators, and limit switches), and applicable on-condition 
actions. The on-condition actions include clearing the seat tracks of 
foreign object debris (FOD), overhauling the HMS, and replacing the 
horizontal actuator. This material also describes procedures for an 
optional terminating action for the repetitive checks by installing a 
serviceable Captain's or First Officer's seat.
    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 ADDRESSES section.

Proposed AD Requirements in This NPRM

    Although this proposed AD does not explicitly restate the 
requirements of AD 2019-22-02, this proposed AD would retain all of the 
requirements of AD 2019-22-02. Those requirements are referenced in the 
service information identified previously, which, in turn, is 
referenced in paragraphs (g) and (h) of this proposed AD.
    This proposed AD would require accomplishing the actions specified 
in the service information already described, 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 service information at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-
2024-2137.

Acceptable Methods of Compliance

    The FAA has determined that the actions required by paragraphs (g) 
and (h) of this 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. Paragraph (j) of 
this AD identifies these conditions. Complying with these conditions 
adequately addresses the unsafe condition identified in this proposed 
AD.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 162 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

to provide cost estimates for the optional terminating action for the 
repetitive checks specified in this proposed 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 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.

    (4) AMOCs approved for AD 2019-22-02 are approved as AMOCs for 
the corresponding provisions of Boeing Special Attention Service 
Bulletin 747-25-3644, Revision 2, dated January 27, 2023, and Boeing 
Special Attention Service Bulletin 747-25-3653, Revision 2, dated 
January 27, 2023, that are required by paragraphs (g) and (h) of 
this AD.
    (5) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(k)(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.
