Special Conditions: Boeing Model 777 

Series Airplanes; Seats With Inflatable 

Lapbelts

AGENCY: Federal Aviation 

Administration (FAA), DOT.

ACTION: Final special conditions.

SUMMARY: These amended special 

conditions are issued to Boeing 

Commercial Airplanes for the Model 

777 series airplanes. These airplanes 

have a novel or unusual design feature 

associated with seats with inflatable 

lapbelts. Special Conditions No. 25–

187–SC were issued on October 3, 2001, 

addressing this issue. Boeing 

subsequently applied to amend the 

special conditions to add a new 

requirement that addresses the 

flammability of the material used to 

construct the inflatable lapbelt. The 

applicable airworthiness regulations, 

including those contained in Special 

Conditions No. 25–187–SC, do not 

contain adequate or appropriate safety 

standards for this design feature. The 

amended special conditions contain the 

additional safety standards that the 

Administrator considers necessary to 

establish an appropriate level of safety 

considering the safety benefits 

associated with the inflatable lapbelt.

DATES: Effective October 29, 2004.

SUPPLEMENTARY INFORMATION: 

Background 

On April 20, 2001, Boeing 

Commercial Airplanes, P.O. Box 3707, 

Seattle, Washington 98124, applied for 

a type certificate design change to 

install inflatable lapbelts for head injury 

64652 Federal Register / Vol. 69, No. 215 / Monday, November 8, 2004 / Rules and Regulations 

protection on certain seats in Boeing 

Model 777 series airplanes. The Model 

777 series airplane is a swept-wing, 

conventional-tail, twin-engine, turbofanpowered transport. The inflatable 

lapbelt is designed to limit occupant 

forward excursion in the event of an 

accident. This will reduce the potential 

for head injury, as determined by the 

Head Injury Criteria (HIC) measurement. 

The inflatable lapbelt behaves similarly 

to an automotive airbag, but in this case 

the airbag is integrated into the lapbelt, 

and inflates away from the seated 

occupant. While airbags are now 

standard in the automotive industry, the 

use of an inflatable lapbelt is novel for 

commercial aviation. 

Because the existing airworthiness 

standards of 14 CFR part 25 do not 

address inflatable lapbelts, the FAA 

developed special conditions to address 

this design feature. Special Conditions 

No. 25–187–SC were issued to Boeing 

Commercial Airplanes on October 3, 

2001, and published in the Federal 

Register on October 12, 2001 (66 FR 

52017). 

On February 26, 2004, The Boeing 

Company requested that the FAA 

amend SC No. 25–187–SC to address 

flammability of the airbag material. 

During the development of the inflatable 

lapbelt the manufacturer was unable to 

develop a fabric that would meet the 

inflation requirements for the bag and 

the flammability requirements of Part 

I(a)(1)(i) of appendix F to part 25. The 

fabrics that were developed that meet 

the flammability requirement did not 

produce acceptable deployment 

characteristics. However, the 

manufacturer was able to develop a 

fabric the meets the less stringent 

flammability requirements of Part 

I(a)(1)(iv) of appendix F to part 25 and 

has acceptable deployment 

characteristics. 

Discussion 

Part I of appendix F to part 25 

specifies the flammability requirements 

for interior materials and components. 

There is no reference to inflatable 

restraint systems in appendix F because 

such devices did not exist at the time 

the flammability requirements were 

written. The existing requirements are 

based on both material types, as well as 

use, and have been specified in light of 

the state-of-the-art of materials available 

to perform a given function. In the 

absence of a specific reference, the 

default requirement would be for the 

type of material used to construct the 

inflatable restraint, which is a fabric in 

this case. However, in writing a special 

condition, the FAA must also consider 

the use of the material, and whether the 

default requirement is appropriate. In 

this case, the specialized function of the 

inflatable restraint means that highly 

specialized materials are needed. The 

standard normally applied to fabrics is 

a 12-second vertical ignition test. 

However, materials that meet this 

standard do not perform adequately as 

inflatable restraints. Since the safety 

benefit of the inflatable restraint is very 

significant, the flammability standard 

appropriate for these devices should not 

screen out suitable materials, thereby 

effectively eliminating use of inflatable 

restraints. The FAA will need to 

establish a balance between the safety 

benefit of the inflatable restraint and its 

flammability performance. At this time, 

the 2.5-inch per minute horizontal test 

is considered to provide that balance. 

As the state-of-the-art in materials 

progresses (which is expected), the FAA 

may change this standard in subsequent 

special conditions to account for 

improved materials. 

The additional safety standard is 

added as Item 14 to existing SC 25–187–

SC. Items 1 through 13 are standards 

already adopted in Special Conditions 

No. 25–187–SC. 

Type Certification Basis 

Under the provisions of § 21.101, 

Boeing Commercial Airplanes must 

show that the Model 777 series 

airplanes, as changed, continue to meet 

the applicable provisions of the 

regulations incorporated by reference in 

Type Certificate No. T00001SE, or the 

applicable regulations in effect on the 

date of application for the change. The 

regulations incorporated by reference in 

the type certificate are commonly 

referred to as the ‘‘original type 

certification basis.’’ The regulations 

incorporated by reference in Type 

Certificate No. T00001SE are as follows: 

Amendments 25–1 through 25–82 for 

the Model 777–200, and amendments 

25–1 through 25–86 with exceptions for 

the Model 777–300. The U.S. type 

certification basis for the Model 777 is 

established in accordance with §§ 21.29 

and 21.17 and the type certification 

application date. The U.S. type 

certification basis is listed in Type 

Certificate Data Sheet No. T00001SE. 

If the Administrator finds that the 

applicable airworthiness regulations 

(i.e., part 25 as amended) do not contain 

adequate or appropriate safety standards 

for Boeing Model 777 series airplanes 

because of a novel or unusual design 

feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Boeing Model 777 must 

comply with the fuel vent and exhaust 

emission requirements of part 34 and 

the noise certification requirements of 

part 36.

Special conditions, as defined in 

§ 11.19, are issued in accordance with 

§ 11.38 and become part of the type 

certification basis in accordance with 

§ 21.101. 

Applicability 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the type certificate 

for that model be amended later to 

include any other model that 

incorporates the same novel or unusual 

design feature, or should any other 

model already included on the same 

type certificate be modified to 

incorporate the same or similar novel or 

unusual design feature, the special 

conditions would also apply to the other 

model under the provisions of § 21.101. 

Discussion of Comments 

Notice of proposed amendment of 

Special Conditions No. 25–187–SC was 

published in the Federal Register on 

September 23, 2004 as Notice 25–04–

03–SC (69 FR 56961). We received one 

comment. 

Comment: The commenter states that 

the special conditions should address 

the Model 747, A340, and A380 

airplanes as well. As written the special 

conditions give the Model 777 a 

marketing advantage over these other 

airplanes that are used in similar 

markets. The Model 747, A340, and 

A380 should have the ability to take 

advantage of this functionality until a 

suitable material is found that addresses 

the functionality of the system as well 

as the 12-second vertical burn 

requirements. 

FAA Reply: The special conditions are 

not a rule of general applicability and 

therefore cannot be applied to other 

airplanes such as the Model 747, A340, 

and A380. However, should an 

applicant apply for certification of an 

airplane with the same or similar design 

of inflatable lapbelts, we would 

consider that request for a less stringent 

flammability requirement for the 

inflatable bag fabric as well. We would 

consider the state-of-the-art inflatable 

bag fabric at that time. 

Under standard practice, the effective 

date of final or amended special 

conditions would be 30 days after the 

date of publication in the Federal 

Register. However, because delivery of 

the affected airplanes with this 

additional novel or unusual design 

feature is imminent, and because a 

delay would significantly affect the 

applicant’s installation and type 

Federal Register / Vol. 69, No. 215 / Monday, November 8, 2004 / Rules and Regulations 64653

certification of the lapbelt, the FAA 

finds that good cause exists for making 

these amended special conditions 

effective upon issuance. 

Conclusion 

This action affects only certain novel 

or unusual design features on the 

Boeing Model 777 series airplanes. It is 

not a rule of general applicability, and 

it affects only Model 777 series 

airplanes listed on Type Certificate Data 

Sheet T00001SE.

Authority Citation 

The authority citation for these 

special conditions is as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701, 

44702, 44704.

The Amended Special Conditions 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the following amended 

special conditions are issued as part of 

the type certification basis for the 

Boeing Model 777 series airplanes with 

inflatable lapbelts installed. 

1. Seats With Inflatable Lapbelts. It 

must be shown that the inflatable 

lapbelt will deploy and provide 

protection under crash conditions 

where it is necessary to prevent serious 

head injury. The means of protection 

must take into consideration a range of 

stature from a two-year-old child to a 

ninety-fifth percentile male. The 

inflatable lapbelt must provide a 

consistent approach to energy 

absorption throughout that range. In 

addition, the following situations must 

be considered: 

a. The seat occupant is holding an 

infant. 

b. The seat occupant is a child in a 

child restraint device. 

c. The seat occupant is a child not 

using a child restraint device. 

d. The seat occupant is a pregnant 

woman. 

2. The inflatable lapbelt must provide 

adequate protection for each occupant 

regardless of the number of occupants of 

the seat assembly, considering that 

unoccupied seats may have active 

seatbelts. 

3. The design must prevent the 

inflatable lapbelt from being either 

incorrectly buckled or incorrectly 

installed such that the inflatable lapbelt 

would not properly deploy. 

Alternatively, it must be shown that 

such deployment is not hazardous to the 

occupant and will provide the required 

head injury protection. 

4. It must be shown that the inflatable 

lapbelt system is not susceptible to 

inadvertent deployment as a result of 

wear and tear, or inertial loads resulting 

from in-flight or ground maneuvers 

(including gusts and hard landings), 

likely to be experienced in service. 

5. Deployment of the inflatable lapbelt 

must not introduce injury mechanisms 

to the seated occupant, or result in 

injuries that could impede rapid egress. 

This assessment should include an 

occupant who is in the brace position 

when it deploys and an occupant whose 

belt is loosely fastened.

6. It must be shown that an 

inadvertent deployment that could 

cause injury to a standing or sitting 

person is improbable. 

7. It must be shown that inadvertent 

deployment of the inflatable lapbelt 

during the most critical part of the flight 

will either not cause a hazard to the 

airplane or is extremely improbable. 

8. It must be shown that the inflatable 

lapbelt will not impede rapid egress of 

occupants 10 seconds after its 

deployment. 

9. The system must be protected from 

lightning and HIRF. The threats 

specified in Special Condition No. 25–

ANM–78 are incorporated by reference 

for the purpose of measuring lightning 

and HIRF protection. For the purposes 

of complying with HIRF requirements, 

the inflatable lapbelt system is 

considered a ‘‘critical system’’ if its 

deployment could have a hazardous 

effect on the airplane; otherwise it is 

considered an ‘‘essential’’ system. 

10. The inflatable lapbelt must 

function properly after loss of normal 

aircraft electrical power, and after a 

transverse separation of the fuselage at 

the most critical location. A separation 

at the location of the lapbelt does not 

have to be considered. 

11. It must be shown that the 

inflatable lapbelt will not release 

hazardous quantities of gas or 

particulate matter into the cabin. 

12. The inflatable lapbelt installation 

must be protected from the effects of fire 

such that no hazard to occupants will 

result. 

13. There must be a means for a 

crewmember to verify the integrity of 

the inflatable lapbelt activation system 

prior to each flight or it must be 

demonstrated to reliably operate 

between inspection intervals. 

14. The inflatable material may not 

have an average burn rate of greater than 

2.5 inches/minute when tested using the 

horizontal flammability test as defined 

in 14 CFR part 25, appendix F, part I, 

paragraph (b)(5).

Airworthiness Directives; Rolls-Royce

Engines

AGENCY: Federal Aviation

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for RollsRoyce plc (RR) RB211 Trent 700 series 

turbofan engines. This AD requires 

initial and repetitive borescope 

inspections of the high pressure-andintermediate pressure (HP–IP) turbine 

internal and external oil vent tubes for 

coking and carbon buildup, and 

cleaning or replacing the vent tubes if 

necessary. This AD results from a report 

of a RB211 Trent 700 series engine 

experiencing a disk shaft separation, 

overspeed of the IP turbine rotor, and 

multiple blade release of IP turbine 

blades. Preliminary findings suggest 

these events resulted from an internal 

oil fire in the HP–IP turbine oil vent 

tubes due to coking and carbon buildup. 

This fire led to a second fire in the 

internal air cavity below the IP turbine 

disk drive shaft. We are issuing this AD 

to prevent internal oil fires due to 

coking and carbon buildup, that could 

cause uncontained engine failure and 

damage to the airplane.

DATES: Effective November 23, 2004. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the 

regulations as of November 23, 2004. 

We must receive any comments on 

this AD by January 7, 2005.
