DESIGN CRITERIA FOR ENCLOSED STOWAGE COMPARTMENTS NOT LIMITED TO STOWAGE OF EMERGENCY OR AIRPLANESUPPLIED EQUIPMENT

Fire protection features 

Stowage compartment interior volumes 

Less than 25 cubic 

feet 

25 cubic feet to 57 

cubic feet 

57 cubic feet to 200 

cubic feet 

Materials of Construction 1 ......................................................................... Yes ........................... Yes ........................... Yes. 

Detectors 2 .................................................................................................. No ............................. Yes ........................... Yes. 

Liner 3 .......................................................................................................... No ............................. Conditional ................ Yes. 

Locating Device 4 ........................................................................................ No ............................. Yes ........................... Yes. 

1 Compliant Materials of Construction 

The material used in constructing each enclosed stowage compartment must at least be fire resistant and must meet the flammability standards established for interior components (i.e., 14 CFR part 25 Appendix F, parts I, IV, and V) per the requirements of § 25.853. For compartments less than 25 ft3 in interior volume, the design must ensure the ability to contain a fire likely to occur within the compartment under normal 

use. 2Smoke or Fire Detectors 

Enclosed stowage compartments equal to or exceeding 25 ft3 in interior volume must be provided with a smoke or fire detection system to ensure that a fire can be detected within a one-minute detection time. Flight tests must be conducted to show compliance with this requirement. 

Each system (or systems) must provide: 

(a) A visual indication in the flight deck within one minute after the start of a fire. 

(b) An aural warning in the OFAR compartment. 

(c) A warning in the main passenger cabin. This warning must be readily detectable by a flight attendant, taking into consideration the positioning of flight attendants throughout the main passenger compartment during various phases of flight. 3 Liner 

If material used in constructing the stowage compartment can be shown to meet the flammability requirements of a liner for a Class B cargo 

compartment (i.e., § 25.855 at Amendment 25–93, and Appendix F, part I, paragraph (a)(2)(ii)), then no liner would be required for enclosed 

stowage compartments equal to or greater than 25 ft3 in interior volume but less than 57 ft3 in interior volume. For all enclosed stowage compartments equal to or greater than 57 ft3 in interior volume but less than or equal to 200 ft3, a liner must be provided that meets the requirements of 

§ 25.855 for a Class B cargo compartment. 4Fire Location Detector 

If an OFAR compartment has enclosed stowage compartments exceeding 25 ft3 interior volume that are located separately from the other 

stowage compartments (for example, away from one central location, such as the entry to the OFAR compartment or a common area within the 

OFAR compartment) that compartment would require additional fire protection features and/or devices to assist the firefighter in determining the 

location of a fire.

SUPPLEMENTARY INFORMATION: 

History 

On May 18, 2011, the FAA published 

in the Federal Register a notice of 

proposed rulemaking to amend Class D 

airspace for Denton, TX, creating 

additional controlled airspace at Denton 

Municipal Airport (76 FR 28684) Docket 

No. FAA–2010–1327. Interested parties 

were invited to participate in this 

rulemaking effort by submitting written 

comments on the proposal to the FAA. 

No comments were received. Class D 

airspace designations are published in 

paragraph 5000 of FAA Order 7400.9U 

dated August 18, 2010, and effective 

September 15, 2010, which is 

incorporated by reference in 14 CFR 

71.1. The Class D airspace designations 

listed in this document will be 

published subsequently in the Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) Part 71 by 

creating additional Class D airspace for 

new standard instrument approach 

procedures at Denton Municipal 

Airport, Denton, TX. This action is 

necessary for the safety and 

management of IFR operations at the 

airport. The geographic coordinates of 

Denton Municipal Airport are also being 

updated to coincide with the FAA’s 

aeronautical database. With the 

exception of this change, this action is 

the same as that published in the 

NPRM. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this 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 rule, when 

promulgated, will not have a significant 

economic impact on a substantial

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the U.S. Code. Subtitle 1, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the agency’s 

authority. This rulemaking is 

promulgated under the authority 

described in subtitle VII, part A, subpart 

I, section 40103. Under that section, the 

FAA is charged with prescribing 

regulations to assign the use of airspace 

necessary to ensure the safety of aircraft 

and the efficient use of airspace. This 

regulation is within the scope of that 

authority as it amends controlled 

airspace for Denton Municipal Airport, 

Denton, TX.
