Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain The Boeing Company Model 787-8, 787-9, and 787-10 
airplanes. This proposed AD was prompted by a report that during 
regular pre-flight checks multiple door assist handles failed by 
pulling loose from their lower attachment point in the doorway support 
bracket. This proposed AD would require, depending on airplane 
configuration, doing an inspection of the forward and aft door assist 
handles for correct installation, installing a new retainer above the 
lower keyway of the support bracket assembly at certain locations, 
installing a placard on certain support bracket assemblies, 
reidentifying the support bracket assembly, and replacing the upper 
spring clip. 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 November 7, 
2022.

SUPPLEMENTARY INFORMATION:

Comments Invited

    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-2022-0876; Project Identifier 
AD-2021-00999-T'' 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 
https://www.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 
Brandon Lucero, Aerospace Engineer, Cabin Safety and Environmental 
Systems Section, FAA, Seattle ACO Branch, 2200 South 216th St., Des 
Moines, WA 98198; phone: 206-231-3569; email: [email protected]. 
Any commentary that the FAA receives that is not specifically 
designated as CBI will be placed in the public docket for this 
rulemaking.

Background

    The FAA has received a report indicating that during regular pre-
flight checks multiple door assist handles failed by pulling loose from 
their lower attachment point in the doorway support bracket. Boeing 
determined that a lower maximum allowable door assist handle flex 
value, coupled with an out-of-tolerance door assist handle, contributed 
to this failure. Loose door assist handles create a safety issue during 
normal and emergency use of the door if the door assist handles detach 
from the door. This condition, if not addressed, could result in injury 
to passengers, crew, or maintenance personnel due to falling out of the 
airplane when opening the door, and could limit exit from the airplane 
during a time-limited emergency evacuation.

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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Requirements Bulletin B787-81205-SB250253-
00 RB, Issue 001, dated June 18, 2021. This service information 
specifies procedures for, depending on airplane configuration, doing a 
detailed inspection of the forward and aft door assist handles for 
correct installation, installing a new retainer above the lower keyway 
of the support bracket assembly at the left- and right-side passenger 
entry doors 1, 2, 3, and 4 located at the forward and aft door assist 
handle, installing a placard on the forward and aft support bracket

assembly, and replacing the upper spring clip.
    The FAA reviewed Boeing Requirements Bulletin B787-81205-SB250254-
00 RB, Issue 001, dated February 22, 2021. This service information 
specifies procedures for installing a new retainer above the lower 
keyway of the support bracket assembly at the left- and right-side 
passenger entry doors 1, 2, 3, and 4 located at the forward and aft 
door assist handle, and reidentifying the support bracket assembly with 
a new part number.
    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.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information already described and 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 https://www.regulations.gov by 
searching for and locating Docket No. FAA-2022-0876.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 123 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 and installation (for    20 work-hours x $85              $160          $1,860  $212,040 (114
 Model 787-8 and 787-9 airplanes).   per hour = $1,700.                                     airplanes).
Installation and reidentification   28 work-hours x $85               160           2,540  $22,860 (9

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

    The FAA estimates the following costs to do any necessary 
replacement 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 this replacement:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Replacement...................................  1 work-hours x $85 per hour =               $160            $245
                                                 $85.
----------------------------------------------------------------------------------------------------------------

    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.

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.
