Federal Register / Vol. 69, No. 184 / Thursday, September 23, 2004 / Proposed Rules 56963

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(g), 40113, 44701, 

44702, 44704. 

The Proposed Special Conditions 

Accordingly, the Federal Aviation 

Administration proposes the following 

additional special condition (Item No. 

14) as part of the type certification basis 

for the Boeing Model 777 series 

airplanes with inflatable lapbelts 

installed. (Existing special condition 

Items 1–13 are repeated below for 

clarity only.). 

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). 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.

Proposed Modification of Class D 

Airspace; Grissom ARB, IN

AGENCY: Federal Aviation 

Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking.

SUMMARY: This document proposes to 

modify Class D airspace at Grissom 

ARB, IN, where Instrument Flight Rules 

Category E circling procedures are being 

used. Increasing the current radius of 

the Class D airspace area will allow for 

a lower Circling Minimum Descent 

Altitude. Controlled airspace extending 

upward from the surface of the earth is 

needed to contain aircraft executing 

these approach procedures. This action 

would increase the area of the existing 

controlled airspace for Grissom ARB, 

IN.

DATES: Comments must be received on 

or before November 25, 2004.

ADDRESSES: Send comments on the 

proposal to the Docket Management 

System, U.S. Department of 

Transportation, Room Plaza 401, 400

docket Number FAA–2004–17896/

beginning of your comments. You may 

also submit comments on the Internet at 

http://dms.dot.gov. You may review the 

public docket containing the proposal, 

any comments received, and any final 

disposition in person in the Dockets 

Office between 9 a.m. and 5 p.m., 

Monday through Friday, except Federal 

holidays. The Docket Office (telephone

Rulemaking Distribution System, which 

describes the application procedure. 

The Proposal 

The FAA is considering an 

amendment to 14 CFR part 71 to modify 

Class D airspace at Grissom AFB, IN. 

Controlled airspace extending upward 

from the surface of the earth is needed 

to contain aircraft executing instrument 

approach procedures. The area would 

be depicted on appropriate aeronautical 

charts. Class D airspace areas extending 

upward from the surface of the earth are 

published in paragraph 5000 of FAA 

Order 7400.9L dated September 2, 2003, 

and effective September 16, 2003, which 

is incorporated by reference in 14 CFR 

71.1. The Class E designations listed in 

this document would be published 

subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

establishment body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. 

Therefore this, proposed regulation—(1) 

is not a ‘‘significant regulatory action’’

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

Regulatory Evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified that this proposed rule will 

not have a significant economic impact 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

1963 Comp., p. 389.

§ 71.1 [Amended] 

2. The incorporation by reference in 

14 CFR 71.1 of the Federal Aviation

Proposed Modification of Class E 

Airspace; Hibbing, MN

AGENCY: Federal Aviation 

Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking.

SUMMARY: This document proposes to 

modify Class E airspace at Hibbing, MN. 

Standard Instrument Approach 

Procedures have been developed for 

Chisholm-Hibbing Airport, Hibbing, 

MN. Controlled airspace extending 

upward from 700 feet or more above the 

surface of the earth is needed to contain 

aircraft executing these approach 

procedures. This action would increase 

the area of existing controlled airspace 

for Chisholm-Hibbing Airport.
