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 all 

The Boeing Company Model DC–9–81 

(MD–81), DC–9–82 (MD–82), DC–9–83 

(MD–83), DC–9–87 (MD–87), and MD– 

88 airplanes, and Model DC–9–10, DC– 

9–20, DC–9–30, DC–9–40, and DC–9–50 

series airplanes. This proposed AD was 

prompted by the discovery of jammed 

elevators during takeoff. This proposed 

AD would require revising the 

‘‘Certificate Limitations’’ section of the 

existing airplane flight manual (AFM) to 

include a procedure to confirm elevator 

surfaces are not jammed in the trailing 

edge down (TED) position. 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 January 6, 2025. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

regulations.gov. Follow the instructions 

for submitting comments. 

• Fax: 202–493–2251.

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 the ADDRESSES section. Include 

‘‘Docket No. FAA–2024–2427; Project 

Identifier AD–2024–00484–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 

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 Katherine Venegas, 

Aviation Safety Engineer, FAA, 3960 

Paramount Boulevard, Lakewood, CA 

90712; phone: 562–627–5353; email: 

katherine.venegas@faa.gov. 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 both the left and right 

elevator were jammed during takeoff 

resulting in a runway excursion. 

Elevator surface jamming in the TED 

direction caused by high-speed wind 

events can occur while the airplane is 

parked. This condition may not be 

detected by feel during preflight control 

column movement prior to takeoff. The 

FAA is issuing this AD to address the 

unsafe condition, which if not 

addressed, could result in a runway 

excursion during a rejected takeoff. 

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. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

revising the ‘‘Certificate Limitations’’ 

section of the existing AFM to include 

a procedure to confirm elevator surfaces 

are not jammed in the TED position. 

Compliance With AFM Revisions 

Section 91.9 (14 CFR 91.9) prohibits 

any person from operating a civil 

aircraft without complying with the 

operating limitations specified in the 

AFM. FAA regulations also require 

operators to furnish pilots with any 

changes to the AFM (14 CFR 121.137) 

and pilots in command to be familiar 

with the AFM (14 CFR 91.505). 

Interim Action 

The FAA considers that this proposed 

AD would be an interim action. Boeing 

is developing a design change to address 

the unsafe condition. If final action is 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 89, No. 226 / Friday, November 22, 2024 / Proposed Rules 92611 

later identified, the FAA might consider 

further rulemaking. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 104 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

AFM revision ........................... 1 work-hour × $85 per hour = $85 ......................................... $0 $85 $8,840 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.
