SUPPLEMENTARY INFORMATION: 

Background 

On May 10, 2011, L–3 

Communications applied for a 

supplemental type certificate (STC) for 

therapeutic oxygen for medical use in 

the Boeing Model 747–8 series airplanes 

equipped with executive interiors. The 

Boeing Model 747–8 series airplane, 

which is a derivative of the Boeing 

Model 747–400 airplane currently 

approved under Type Certificate No. 

A20WE, is a four-engine jet transport 

airplane that will have a maximum 

takeoff weight of 970,000 lbs. The 

Model 747–8 airplane will have 153 

seats approved for taxi, takeoff, and 

landing (19 crewmembers and 134 

passengers). 

Section 25.1445 includes standards 

for oxygen distribution systems when 

oxygen is supplied to flightcrew and 

passengers. If a common source of 

supply is used, § 25.1445(a)(2) requires 

a means to separately reserve the 

minimum supply required by the 

flightcrew. This requirement was 

included in § 25.1445 when the 

regulations were codified, and was 

originally added to Civil Air Regulations 

4b.831 at Amendment 4b–13, effective 

September 21, 1949. 

It is apparent that the regulation is 

intended to protect the flightcrew by 

ensuring that an adequate supply of 

oxygen is available to complete a 

descent and landing following a loss of 

cabin pressure. When the regulation was 

written, the only passenger oxygen 

system designs were supplemental 

oxygen systems intended to protect 

passengers from hypoxia in the event of 

a decompression. Existing passenger 

oxygen systems did not include design 

features that would allow the flightcrew 

to control oxygen to passengers during 

flight. There are no similar requirements 

when oxygen is supplied from the same 

source to passengers for use during a 

decompression and for discretionary/

first-aid use any time during the flight. 

In the proposed design, the passenger 

and therapeutic oxygen systems use the 

same source of oxygen. The flightcrew 

oxygen emergency system uses a 

dedicated source of oxygen independent 

from the passenger oxygen system. An 

oxygen duration chart and operation 

procedures will be incorporated into the 

‘‘Flight Crew Operating Manual’’ and 

‘‘Flight Manual Supplement,’’ as part of 

the STC, to provide information to the 

flightcrew to determine when to cease 

operation of the therapeutic system as a 

means by which to reserve the 

minimum supply of supplemental 

passenger oxygen. 

Type Certification Basis 

Under the provisions of § 21.101, L– 

3 Communications must show that the 

Boeing Model 747–8 series airplanes, as 

changed, continue 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 

(i.e., Title 14, Code of Federal 

Regulations (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 supplemental type certificate to 

modify any other model included on the 

same type certificate to incorporate the 

same or similar 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 

series airplanes must comply with the 

fuel vent and 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 

The L–3 Communications 

modifications to the Boeing Model 747– 

8 series airplanes will incorporate the 

following novel or unusual design 

feature: 

L–3 Communications is seeking 

certification of an interior modification 

to Boeing Model 747–8 series airplanes 

to include executive and medical 

patient transport. As a part of the 

executive interior installation, the 

airplane will be outfitted with a 

therapeutic oxygen system. The 

therapeutic oxygen system shares the 

same supply of oxygen with the existing 

passenger oxygen system and consists of 

multiple constant flow oxygen outlets 

located throughout the cabin. The 


Lhorne on DSK7TPTVN1PROD with RULES
36470 Federal Register / Vol. 80, No. 122 / Thursday, June 25, 2015 / Rules and Regulations 

flightcrew can turn the therapeutic 

oxygen system on and off from the flight 

deck to allow use at any point during 

the flight, and to preserve a sufficient 

remaining oxygen reserve, in the event 

therapeutic oxygen is used for medical 

purposes, to accommodate the 

passengers in the event of an emergency 

oxygen situation. 

The gaseous passenger oxygen system 

will be modified to accommodate 

additional supply cylinders and several 

therapeutic oxygen outlets located 

throughout the cabin. Each therapeutic 

outlet will provide a constant flow of 

oxygen at either 2 or 4 liters per minute. 

The flightcrew will be able to control 

the flow of therapeutic oxygen at any 

time during flight. Therapeutic oxygen 

systems previously have been certified, 

and were generally considered an 

extension of the passenger oxygen 

system for the purpose of defining the 

applicable regulations. As a result, the 

applicable regulations included those 

that applied to oxygen systems in 

general, or supplemental oxygen 

systems. 

Discussion 

No specific regulations address the 

design and installation of oxygen 

systems used specifically for therapeutic 

applications. Existing requirements, 

such as §§ 25.1309, 25.1441(b) and (c), 

25.1451, and 24.1453, in the Boeing 

Model 747–8 series airplanes 

certification basis applicable to this STC 

project, provide some design standards 

appropriate for oxygen system 

installations. However, additional 

design standards for systems 

supplementing the existing oxygen 

system are needed to complement the 

existing applicable requirements. The 

addition of equipment involved in this 

installation, and the unsafe conditions 

that can exist when the oxygen content 

of an enclosed area becomes too high 

because of system leaks, malfunction, or 

damage from external sources, make it 

necessary to ensure that adequate safety 

standards are applied to the design and 

installation of the oxygen system in 

Boeing Model 747–8 series airplanes. 

These potential hazards also necessitate 

development and application of 

appropriate additional design and 

installation standards. 

These 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. 

Discussion of Comments 

Notice of proposed special conditions 

No. 25–15–05–SC for the L–3 

Communications modifications to the 

Boeing Model 747–8 series airplanes 

was published in the Federal Register 

on April 30, 2015 (80 FR 24225). No 

comments were received, and the 

special conditions are adopted as 

proposed. 

Applicability 

As discussed above, these special 

conditions are applicable to Boeing 

Model 747–8 series airplanes. Should 

L–3 Communications apply at a later 

date for a supplemental type certificate 

to modify any other model included on 

Type Certificate No. A20WE to 

incorporate the same novel or unusual 

design feature, these special conditions 

would apply to that model as well. 

Under standard practice, the effective 

date of final special conditions would 

be 30 days after the date of publication 

in the Federal Register; however, as the 

certification date for the L–3 

Communications modifications to 

Boeing Model 747–8 series airplanes is 

imminent, the FAA finds that good 

cause exists to make these special 

conditions effective upon publication. 

Conclusion 

This action affects only certain novel 

or unusual design features on one model 

series of 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 

airplane.

therapeutic purposes, the distribution 

system must be designed for either— 

1. A source of supplemental supply 

for protection from hypoxia following a 

loss of cabin pressure, and a separate 

source for therapeutic purposes, or 

2. A common source of supply, with 

means to separately reserve the 

minimum supply required by the 

passengers for supplemental use 

following a loss of cabin pressure.

ACTION: Final special conditions. 

SUMMARY: These special conditions are 

issued for the Bombardier Aerospace 

Model BD–500–1A10 and BD–500– 

1A11 series airplanes. These airplanes 

will have a novel or unusual design 

feature associated with a fly-by-wire 

EFCS that limits pitch- and roll-limiting 

functions to prevent the airplane from 

attaining certain pitch attitudes and roll 

angles. This system generates the actual 

surface commands that provide for 

stability augmentation and flight control 

for all three airplane axes (longitudinal, 

lateral, and directional). The applicable 

airworthiness regulations do not contain 

adequate or appropriate safety standards 

for this design feature. These 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.
