1 Compliant Materials of Construction The material used in constructing each enclosed stowage compartment must at least be fire resistant and must meet the flammabil ity 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 ft 3 in interior volume, the design must ensure the ability to contain a fire likely to occur within the compartment under normal

use.

2 Smoke 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 thi s 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 Cl ass 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 ft 3 in interior volume. For all enclosed stowage compartments equal to or greater than 57 ft 3 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.

4 Fire 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 w ithin the OFAR compartment) that compartment would require additional fire protection features and/or devices to assist the firefighter i n 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

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.

The Rule

This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by establishing Class E airspace extending upward from 700 feet above the surface for new standard instrument approach procedures at Lawrence Smith Memorial Airport, Harrisonville, MO. This action is necessary for the safety and management of IFR operations at the airport. Geographic coordinates are also being updated to coincide with the FAA’s aeronautical database.
