[Docket No. FAA–2024–0190; Notice No. 25– 

24–02–SC] 

Special Conditions: The Boeing 

Company, Boeing Model 747–8 Series 

Airplane; Short-Term Occupancy of 

Lower Lobe During Flight and 

Installation of Stairway Between Main 

Deck and Lower-Lobe 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed special 

conditions. 

SUMMARY: This action proposes special 

conditions for The Boeing Company 

(Boeing) Model 747–8 series airplane. 

This airplane, as modified by Boeing, 

will have a novel or unusual design 

feature when compared to the state of 

technology envisioned in the 

airworthiness standards for transport 

category airplanes. This design feature 

is the installation of stairs for flightcrew 

to access the forward and aft lower lobe 

compartments during flight. These 

compartments will have two main 

functions: storage of service items and 

that of a Class C cargo compartment. 

The applicable airworthiness 

regulations do not contain adequate or 

appropriate safety standards for this 

design feature. These proposed special 

conditions contain the additional safety 

standards that the Administrator 

considers necessary to establish a level 

of safety equivalent to that established 

by the existing airworthiness standards.

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to these special 

conditions contain commercial or 

financial information that is customarily 

treated as private, that you actually treat 

as private, and that is relevant or 

responsive to these special conditions, 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 the 

indicated comments will not be placed 

in the public docket of these proposed 

special conditions. Send submissions 

containing CBI to the individual listed 

in the For Further Information Contact 

section above. Comments the FAA 

receives, which are not specifically 

designated as CBI, will be placed in the 

public docket for these proposed special 

conditions. 

Background 

On July 2, 2018, Boeing applied for a 

supplemental type certificate (STC) for 

the installation of stairs for inflight 

flightcrew to access the forward and aft 

lower lobe compartments that will have 

two main functions: access of service 

items that have been stored and that of 

a Class C cargo compartment in the 

Model 747–8 series airplane. The 

modified Boeing Model 747–8 series 

airplane, which is a derivative of the 

Model 747–8F series airplane currently 

approved under Type Certificate No. 

A20WE, is a four-engine, transport 

category airplane with a VIP interior 

configuration, not for common carriage, 

seating for 93 passengers and 15 

flightcrew, and a maximum takeoff 

weight of 987,000 pounds. 

Type Certification Basis 

Under the provisions of title 14, Code 

of Federal Regulations (14 CFR) 21.101, 

Boeing must show that changes to the 

Boeing Model 747–8 series airplane, as 

changed, continues to meet the 

applicable provisions of the regulations 

listed in Type Certificate No. A20WE or 

the applicable regulations in effect on 

the date of application for the change, 

except for earlier amendments as agreed 

upon by the FAA. 

If the Administrator finds that the 

applicable airworthiness regulations 

(e.g., 14 CFR part 25) do not contain 

adequate or appropriate safety standards 

for the Boeing Model 747–8 series 

airplanes because of a novel or unusual 

design feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the applicant apply 

for a STC to modify any other model 

included on the same type certificate to 

incorporate the same novel or unusual 

design feature, these special conditions 

would also apply to the other model 

under § 21.101. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Boeing Model 747–8 


khammond on DSK9W7S144PROD with PROPOSALS
Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 94621 

series airplanes must comply with the 

exhaust-emission requirements of 14 

CFR part 34, and the noise-certification 

requirements of 14 CFR part 36. 

The FAA issues special conditions, as 

defined in 14 CFR 11.19, in accordance 

with § 11.38, and they become part of 

the type certification basis under 

§ 21.101. 

Novel or Unusual Design Features 

Certain Boeing Model 747–8 series 

airplanes will incorporate the following 

novel or unusual design features: 

The installation of stairs for flightcrew 

to access the forward and aft lower lobe 

compartments during flight. The 

compartments will have two main 

functions: storage of service items and 

that of a Class C cargo compartment. 

Discussion 

Existing regulations address service 

areas and Class C cargo compartments 

independently, but do not address 

compartments that have both uses. A 

service compartment can be occupied, 

and the Class C cargo compartment 

cannot. Further, firefighting is dealt 

with differently in each compartment. 

The crew fights a fire in a service 

compartment and a flooding 

suppression system is used to fight a fire 

in a Class C cargo compartment. 

The proposed special conditions 

contain the additional safety standards 

that the Administrator considers 

necessary to establish a level of safety 

equivalent to that established by the 

existing airworthiness standards. 

Applicability 

As discussed above, these proposed 

special conditions are applicable to the 

Boeing Model 747–8 airplanes as 

modified by Boeing. Should the 

applicant apply for a STC to modify any 

other model included on the same type 

certificate to incorporate the same novel 

or unusual design feature, these special 

conditions would apply to the other 

model as well. 

Conclusion 

This action affects only a certain 

novel or unusual design feature on 

certain modified Boeing Model 747–8 

series airplanes. It is not a rule of 

general applicability and affects only 

the applicant who applied to the FAA 

for approval of these features on the 

airplanes. 

List of Subjects in 14 CFR Part 25 

Aircraft, Aviation safety, reporting, 

and recordkeeping requirements. 

Authority Citation 

The authority citation for these 

special conditions is as follows: 

Authority: 49 U.S.C. 106(f), 106(g), 40113, 

44701, 44702, and 44704. 

The Proposed Special Conditions 

Accordingly, the Federal Aviation 

Administration (FAA) proposes the 

following special conditions as part of 

the type certification basis for Boeing 

Model 747–8 series airplanes, as 

modified by The Boeing Company. 

Requirements Specific to Lower Lobe 

Access 

(a) Alerts and indications are required 

in the lower lobe compartments to 

indicate decompression, smoke/fire 

detection, and the need to return to 

one’s seat. (Definition for alert 

categorization must be consistent with 

14 CFR 25.1322). 

(1) There must be a flight deck 

indication to advise the flightcrew when 

the lower lobe service/cargo 

compartment(s) are occupied. The 

indication must be accompanied by a 

placard or message in the flight deck 

indicating someone is in the lower lobe 

compartment(s). The flight deck 

indication must be initiated 

automatically when the compartments 

become occupied, without input from 

the occupying flightcrew other than 

required to gain access. The flight deck 

indication must be canceled 

automatically when the compartment(s) 

are no longer occupied, and the means 

of access is returned to the unoccupied 

configuration. 

(i) There must be flight deck 

indication to advise the flightcrew that 

the in-flight accessible doors to the 

lower lobe compartments are closed 

prior to initiation of the fire suppression 

system. 

(2) There must be an ‘‘on/off’’ visual 

alert light located outside and on or near 

the access doors to each lower lobe 

service/cargo compartment with a 

placard stating, ‘‘When light is 

illuminated entrance is prohibited’’ (or 

similar words). The alert is to be 

automatic in the event of 

decompression, smoke/fire detection or 

anytime the compartment visual alerting 

system is activated. 

(3) A flightcrew operated visual 

alerting system, which is recognized in 

accessible areas within the lower lobe 

compartment(s), must be installed to 

indicate, during turbulence, that 

persons must return to their seats. 

Appropriate procedures and limitations 

(if required) must be established to 

ensure that the flightcrew alerting 

systems notify the occupants to return 

to their seats at the onset of turbulence 

and prior to taxi, takeoff and landing. 

(4) An automatically activated aural 

and visual decompression alerting 

system must be present and 

immediately recognizable in accessible 

areas of the lower lobe compartments to 

notify occupants when to don oxygen 

masks. 

(5) An automatically activated aural 

and visual alerting system, which is 

recognized in the lower lobe 

compartment(s), must be installed. This 

aural and visual alerting system is to 

indicate that, in the event of smoke 

detection in the lower lobe 

compartment(s), persons must don their 

oxygen masks and initiate oxygen flow, 

exit the compartment, ensure that the 

door is closed (smoke barrier) and that 

communication with the flight deck is 

established. Entry must not be allowed 

during flight after release of fire 

suppressant. 

(6) These alerting requirements must 

be distinctive and effective, and: 

(i) Visual alerts must be visible from 

all occupant locations during all 

expected operational conditions 

including a rapid decompression where 

moisture in the air may condense. 

(ii) Aural alerts must be loud enough 

to be heard during all expected 

operational conditions including a rapid 

decompression where the ambient noise 

level will increase. 

(iii) If there are two or more alerts that 

an occupant may hear or is expected to 

respond to, there must be an automatic 

visual alert in addition to the automatic 

aural alert. There must be training in the 

sound of the alerting system, the 

meaning of the alerting system, and the 

response to the signal (i.e., procedures 

for donning the masks and activating 

the flow of oxygen). 

(b) Placards 

(1) There must be appropriate 

placards installed inside and outside 

each access door to the lower lobe 

compartment(s) to indicate: 

(i) The maximum number of 

occupants allowed, or number of 

occupants required, as applicable to the 

compartment. 

(ii) Occupancy is restricted to 

crewmembers trained in the procedures 

of the lower lobe compartment(s). 

(iii) Occupancy is prohibited during 

taxi, takeoff, and landing, and whilst the 

fire suppression system is activated. 

(iv) The access door must remain 

closed except when someone is entering 

or exiting the compartment. 

(v) Occupancy of the compartment 

should be of minimum duration. 

(vi) Anyone entering the lower lobe 

compartment(s) during flight must carry 

portable oxygen equipment for the 

entire time that they are in the 

compartment. 

(2) There must be appropriate 

placards located conspicuously on or 


khammond on DSK9W7S144PROD with PROPOSALS
94622 Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 

near each lower lobe compartment exit 

defining the location and operating 

instructions for each evacuation route. 

Placards must be readable from a 

distance of 30 inches under emergency 

lighting conditions. 

(3) There must be a placard located 

adjacent to the visual alert light required 

by condition (a) (2) that states, ‘‘When 

light is illuminated, entrance is 

prohibited’’ (or similar words). 

(4) In addition to the above 

requirements, the following additional 

placards must be included for an 

Electronic/Equipment (E/E) Bay: 

(i) No stowage allowed within an E/ 

E Bay. 

(ii) In-flight access for panels/cabinets 

not designed to be used in-flight is 

prohibited. 

(iii) Provided the in-flight 

maintenance requirements in ICA 

section (g) are met, placarding must 

declare that ‘‘Entrance is prohibited 

except by permission of the pilot in 

command’’ (or similar words). 

(iv) ‘‘Access is not permitted during 

flight’’ if the in-flight maintenance 

requirements in ICA Section (g) are not 

met. 

(v) A placard must be installed on all 

access panels and doors within lower 

lobe compartments prohibiting use of 

those that are not intended for use in 

flight. 

(c) Equipment: In lieu of that required 

by §§ 25.819, 25.851(a), 25.1439(a) and 

25.1447(c) the following equipment is 

required: 

(1) There must be a portable oxygen 

bottle with mask attached to it meeting 

the requirements § 25.1439(b)(1), (2)(i), 

(4) for each crewmember occupying the 

lower lobe compartment(s). The 

equipment must be mounted outside 

each access door to the lower lobe 

service/cargo compartment(s). The 

equipment and system must be designed 

to prevent any inward leakage to the 

inside of the device and prevent any 

outward leakage causing significant 

increase in the oxygen content of the 

local atmosphere (i.e., full face mask 

type). A portable oxygen bottle must be 

carried by each crewmember who is 

occupying the lower lobe service/cargo 

compartment. The portable oxygen 

bottle must also meet the minimum 

performance requirements of 

§ 25.1443(a) or (b), or the equipment 

must be shown to protect the occupant 

from hypoxia at an activity level 

required to return to a seat on the main 

deck where oxygen is available 

following a rapid decompression. 

(2) In addition to the emergency 

illumination required by § 25.819(a), at 

least two flashlights, each equipped 

with a locator light, must be provided. 

One flashlight must be located adjacent 

to each emergency exit and entrance in 

the lower lobe compartment(s). 

(3) In addition to the evacuation route 

requirements of § 25.819(a), all 

entrances and exits from the lower lobe 

service/cargo compartment must be 

capable of being closed after entering 

and exiting and, after closing, must 

prevent hazardous quantities of smoke, 

flames, or fire suppressant agent from 

entering any compartments occupied by 

passengers or crew and must prevent 

loss of fire suppressant agent when 

activated. 

(4) In lieu of the emergency 

equipment required by §§ 25.851(a) and 

25.1439(a), when the procedures allow 

for a single occupant in a potential 

‘‘dead end’’ volume further than 5 feet 

from an exit in the lower lobe 

compartment(s) there must be a readily 

accessible fire extinguisher, appropriate 

to the types and kinds of fires that may 

occur. 

(5) A means must be in place to 

preclude anyone from being trapped 

inside the lower lobe compartment(s). If 

a locking mechanism is installed in the 

door, it must be capable of being 

unlocked from the either side of the 

door without the aid of any tools. 

(6) A means must be in place to 

restrict access and prevent inadvertent 

damage to critical aircraft systems and 

equipment located within the 

compartment during flight. 

(7) There must be a means to 

communicate with the flight deck from 

within the E/E Bay. 

(d) Training: Training manuals and 

training must include: 

(1) Use and actions associated with 

aural and visual alerts and placards 

specified herein. 

(2) Entering and exiting the lower lobe 

compartment(s), including emergency 

exiting. 

(3) Checking the oxygen bottle 

pressure for adequacy prior to entering 

the lower lobe service/cargo 

compartment. 

(4) Carrying the oxygen bottle when 

entering the lower lobe compartment(s) 

and using the bottle in emergency 

situations. 

(5) Maintaining exit path aisle and 

access for the evacuation routes. 

(6) Identification of equipment related 

hazards such as the potential for electric 

shock and burns. 

(7) Limiting the occupancy for 

duration of the required tasks. 

(e) Procedures 

(1) A procedure must be established 

to ensure that the appropriate actions 

are taken in the event of smoke/fire 

detection. These actions are to include 

evacuation of the lower lobe 

compartments if occupied, 

communication with flight deck, 

determination of the event severity and 

the closure of the compartment doors 

for compartment sealing. These actions 

ensure the fire barriers (i.e., doors) are 

closed prior to release of fire 

suppressant agent in the cargo 

compartments. Reentry into the lower 

lobe service/cargo compartments after a 

smoke/fire detection event would only 

be allowed by the pilot in command, via 

controlled procedures. 

(2) A procedure must be established 

to ensure that required equipment, such 

as portable oxygen, fire extinguishers, 

protective breathing equipment, and 

warning light are functional prior to 

takeoff. 

(f) Limitations of Special Condition 

(1) An FAA approved Cabin Crew 

Manual requiring the cabin crew verify 

the lower lobe compartment(s) are not 

occupied during taxi, takeoff, landing, 

or after fire suppression activation must 

be created. The Cabin Crew Manual 

must include instructions for allowing 

access; procedures for fire/smoke 

detection/firefighting; procedures for 

decompression. The Cabin Crew Manual 

must be specified by the master drawing 

list and called out on the description of 

type design change section of the STC. 

(2) The Airplane Flight Manual (AFM) 

supplement must include instructions 

for: allowing access; procedures for fire/ 

smoke detection/firefighting; procedures 

for decompression. 

(3) The weight and balance manual 

must include cargo loading restrictions 

to maintain escape paths. 

(g) Instructions for Continued 

Airworthiness (ICAs) 

(1) The ICAs must contain appropriate 

procedures to ensure maintenance can 

be safely accomplished in-flight. 

(i) The ICA supplement must contain 

instructions that highlight the special 

considerations associated with in-flight 

maintenance. This content includes any 

assumptions or requirements for 

compliance with §§ 25.1309, 25.1360, 

25.1529 and 25.1721. 

(ii) The ICAs must establish an 

appropriate foreign object damage (FOD) 

control process for performing 

maintenance in-flight. The hazards 

associated with FOD may be mitigated 

by design and existing FOD control 

processes. 

(iii) The ICAs must establish an 

appropriate lock-out/tag-out procedure 

for performing maintenance in-flight. A 

new single lock-out/tag-out procedure 

may be created for both ground and 

flight.

Airworthiness Directives; Airbus 

Helicopters (Type Certificate 

Previously Held by Eurocopter France) 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2008–10–01 and AD 2010–05–51, which 

apply to certain Eurocopter France (now 

Airbus Helicopters) Model EC120B 

helicopters. AD 2008–10–01 requires 

replacing certain part-numbered and 

serial-numbered spherical thrust 

bearings. AD 2010–05–51 requires 

repetitively inspecting the main rotor 

(M/R) head rotor hub (rotor hub) and, 

depending on the results, taking 

corrective action. Since the FAA issued 

those ADs, the manufacturer revised the 

airworthiness limitations section (ALS) 

to incorporate various airworthiness 

limitations, tasks, and associated 

thresholds and intervals that were 

previously contained in service 

bulletins, as well as incorporate a new 

task. This proposed AD would require 

revising the ALS of the existing 

maintenance manual (MM) or 

instructions for continued airworthiness 

(ICAs) and the existing approved 

maintenance or inspection program, as 

applicable, as specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is proposed for incorporation 

by reference. The FAA is proposing this 

AD to address the unsafe condition on 

these products. 

DATES: The FAA must receive comments 

on this NPRM by January 13, 2025.
