ACTION: Final special conditions. SUMMARY: These special conditions are issued for the Alenia Model C–27J airplane. This airplane has novel or unusual design features when compared to the state of technology described in the airworthiness standards for transport-category airplanes. These design features include a lavatory in the Class E cargo compartment. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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. The FAA has issued additional special conditions for other novel or unusual design features of the C–27J. DATES: Effective Date: January 22, 2010.

SUPPLEMENTARY INFORMATION: Background On March 27, 2006, the European Aviation Safety Agency (EASA) forwarded to the FAA an application from Alenia Aeronautica of Torino, Italy, for U.S. type certification of a twin-engine, commercial transport designated as the Model C–27J. The C– 27J is a twin-turbopropeller, cargotransport aircraft with a maximum takeoff weight of 30,500 kilograms. Type Certification Basis Under the provisions of § 21.17 of Title 14, Code of Federal Regulations (14 CFR), and the bilateral agreement between the U.S. and Italy, Alenia Aeronautica must show that the C–27J meets the applicable provisions of 14 CFR part 25, as amended by Amendments 25–1 through 25–87. E:\FR\FM\08FER1.SGM 08FER1 Federal Register / Vol. 75, No. 25 / Monday, February 8, 2010 / Rules and Regulations WReier-Aviles on DSKGBLS3C1PROD with RULES Alenia also elects to comply with Amendment 25–122, effective September 5, 2007, for 14 CFR 25.1317. If the Administrator finds that existing airworthiness regulations do not adequately or appropriately address safety standards for the C–27J due to a novel or unusual design feature, the FAA prescribes special conditions under provisions of 14 CFR 21.16. In addition to the applicable airworthiness regulations and special conditions, the C–27J 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, and the FAA must issue a finding of regulatory adequacy under § 611 of Public Law 92–574, the ‘‘Noise Control Act of 1972.’’ 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 § 21.17(a)(2). 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 or similar novel or unusual design feature, the special conditions also apply to the other model under § 21.101. Novel or Unusual Design Features The C–27J incorporates a lavatory into the Class E cargo compartment, which is considered a novel or unusual design feature in a cargo compartment. In developing the airworthiness requirements for cargo compartments, the FAA did not envision that a lavatory would be installed inside a Class E cargo compartment. Lavatories, including the one to be installed in the C–27J, typically contain electrical systems, which could serve as ignition sources for a fire; and an oxygen supply system, which could intensify the growth and size of a fire. Therefore, a means must be provided to disconnect or otherwise remove these two factors, as potentially contributing to a fire, in the event smoke or fire is detected in the cargo compartment and lavatory. The existing airworthiness regulations do not adequately or appropriately address safety standards for these design features. These special conditions for the C–27J 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 Specific regulations governing Class E cargo compartments: VerDate Nov<24>2008 11:08 Feb 05, 2010 Jkt 220001 (a) Section 25.855, the materialstandards and design considerations for cargo-compartment interiors; the statement that each cargo compartment must meet one of the Class requirements of § 25.857; and the flight testing which must be conducted for certification. (b) Section 25.857, the standards for the various classes of transport-category airplane-cargo compartments. (c) Section 25.858, design and certification requirements for cargo- or baggage-compartment fire- or smokedetection systems, and a standard that fire be detected and indicated to the crew less than one minute after inception. Specific regulations governing lavatory installations, regardless of location: (d) Section 25.783, requirements to preclude anyone from becoming trapped inside the lavatory. (e) Section 25.791, lavatory placarding requirements. (f) Section 25.853, interior materialtest standards, smoking-prohibition requirements, ashtray requirements, and waste-receptacle design-and-material standards. (g) Section 25.854, lavatory smokedetector and fire-extinguisher requirements. In developing the airworthiness requirements for cargo compartments, the FAA did not envision that a lavatory would be installed in a Class E cargo compartment. Therefore, special conditions must be established to ensure that means are available to shut off the electrical system in the lavatory, and the oxygen-supply system in the lavatory, in the event of a smokedetector alarm in the cargo compartment or lavatory. Discussion of Comments Notice of proposed special conditions no. 25–09–12–SC for the Alenia Model C–27J airplanes was published in the Federal Register on October 23, 2009. No comments were received, and the special conditions are adopted as proposed. Applicability As discussed above, these special conditions are applicable to the C–27J. Should Alenia apply at a later date for a change to the type certificate to include another model incorporating the same or similar novel or unusual design features, these special conditions apply to that model as well under § 21.101. 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 Alenia Model PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 6093 C–27J airplane is imminent, the FAA finds that good cause exists to make these special conditions effective upon issuance. Conclusion This action affects only certain novel or unusual design features of the Alenia C–27J. It is not a rule of general applicability, and it affects only the applicant that applied to the FAA for approval of these features on the airplane.

SUPPLEMENTARY INFORMATION: WReier-Aviles on DSKGBLS3C1PROD with RULES History On October 29, 2009, the FAA published in the Federal Register a notice of proposed rulemaking to amend Class E airspace at Grand Junction, CO (74 FR 55791). 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 E airspace designations are published in paragraph 6005 of FAA Order 7400.9T signed August 27, 2009, and effective September 15, 2009, which is incorporated by reference in 14 CFR part 71.1. The Class E airspace designations listed in this document will be published subsequently in that Order. VerDate Nov<24>2008 11:08 Feb 05, 2010 Jkt 220001 The Rule This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by modifying the Class E airspace for the Grand Junction, CO, area, adding additional controlled airspace extending upward from 1,200 feet above the surface to accommodate vectoring IFR aircraft departing Grand Junction Regional, Grand Junction, CO, to en route airspace. This action is necessary for the safety and management of IFR operations at the airport. This will also update the airport name from Grand Junction, Walker Field. The FAA has determined 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 discusses 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 establishes additional controlled airspace at Grand Junction Regional, Grand Junction, CO.

Special Conditions: Model C-27J Airplane; Class E Cargo 
Compartment Lavatory

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final special conditions.

-----------------------------------------------------------------------

SUMMARY: These special conditions are issued for the Alenia Model C-27J 
airplane. This airplane has novel or unusual design features when 
compared to the state of technology described in the airworthiness 
standards for transport-category airplanes. These design features 
include a lavatory in the Class E cargo compartment. The applicable 
airworthiness regulations do not contain adequate or appropriate safety 
standards for these design features. 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. The FAA has issued additional 
special conditions for other novel or unusual design features of the C-
27J.

DATES: Effective Date: January 22, 2010.

SUPPLEMENTARY INFORMATION: 

Background

    On March 27, 2006, the European Aviation Safety Agency (EASA) 
forwarded to the FAA an application from Alenia Aeronautica of Torino, 
Italy, for U.S. type certification of a twin-engine, commercial 
transport designated as the Model C-27J. The C-27J is a twin-
turbopropeller, cargo-transport aircraft with a maximum takeoff weight 
of 30,500 kilograms.

Type Certification Basis

    Under the provisions of Sec.  21.17 of Title 14, Code of Federal 
Regulations (14 CFR), and the bilateral agreement between the U.S. and 
Italy, Alenia Aeronautica must show that the C-27J meets the applicable 
provisions of 14 CFR part 25, as amended by Amendments 25-1 through 25-
87.

[[Page 6093]]

Alenia also elects to comply with Amendment 25-122, effective September 
5, 2007, for 14 CFR 25.1317.
    If the Administrator finds that existing airworthiness regulations 
do not adequately or appropriately address safety standards for the C-
27J due to a novel or unusual design feature, the FAA prescribes 
special conditions under provisions of 14 CFR 21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the C-27J 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, and the FAA must issue a finding of 
regulatory adequacy under Sec.  611 of Public Law 92-574, the ``Noise 
Control Act of 1972.''
    The FAA issues special conditions, as defined in 14 CFR 11.19, in 
accordance with Sec.  11.38, and they become part of the type-
certification basis under Sec.  21.17(a)(2).
    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 or similar 
novel or unusual design feature, the special conditions also apply to 
the other model under Sec.  21.101.

Novel or Unusual Design Features

    The C-27J incorporates a lavatory into the Class E cargo 
compartment, which is considered a novel or unusual design feature in a 
cargo compartment. In developing the airworthiness requirements for 
cargo compartments, the FAA did not envision that a lavatory would be 
installed inside a Class E cargo compartment. Lavatories, including the 
one to be installed in the C-27J, typically contain electrical systems, 
which could serve as ignition sources for a fire; and an oxygen supply 
system, which could intensify the growth and size of a fire. Therefore, 
a means must be provided to disconnect or otherwise remove these two 
factors, as potentially contributing to a fire, in the event smoke or 
fire is detected in the cargo compartment and lavatory.
    The existing airworthiness regulations do not adequately or 
appropriately address safety standards for these design features. These 
special conditions for the C-27J 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

    Specific regulations governing Class E cargo compartments:
    (a) Section 25.855, the material-standards and design 
considerations for cargo-compartment interiors; the statement that each 
cargo compartment must meet one of the Class requirements of Sec.  
25.857; and the flight testing which must be conducted for 
certification.
    (b) Section 25.857, the standards for the various classes of 
transport-category airplane-cargo compartments.
    (c) Section 25.858, design and certification requirements for 
cargo- or baggage-compartment fire- or smoke-detection systems, and a 
standard that fire be detected and indicated to the crew less than one 
minute after inception.
    Specific regulations governing lavatory installations, regardless 
of location:
    (d) Section 25.783, requirements to preclude anyone from becoming 
trapped inside the lavatory.
    (e) Section 25.791, lavatory placarding requirements.
    (f) Section 25.853, interior material-test standards, smoking-
prohibition requirements, ashtray requirements, and waste-receptacle 
design-and-material standards.
    (g) Section 25.854, lavatory smoke-detector and fire-extinguisher 
requirements.
    In developing the airworthiness requirements for cargo 
compartments, the FAA did not envision that a lavatory would be 
installed in a Class E cargo compartment. Therefore, special conditions 
must be established to ensure that means are available to shut off the 
electrical system in the lavatory, and the oxygen-supply system in the 
lavatory, in the event of a smoke-detector alarm in the cargo 
compartment or lavatory.

Discussion of Comments

    Notice of proposed special conditions no. 25-09-12-SC for the 
Alenia Model C-27J airplanes was published in the Federal Register on 
October 23, 2009. No comments were received, and the special conditions 
are adopted as proposed.

Applicability

    As discussed above, these special conditions are applicable to the 
C-27J. Should Alenia apply at a later date for a change to the type 
certificate to include another model incorporating the same or similar 
novel or unusual design features, these special conditions apply to 
that model as well under Sec.  21.101.
    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 Alenia 
Model C-27J airplane is imminent, the FAA finds that good cause exists 
to make these special conditions effective upon issuance.

Conclusion

    This action affects only certain novel or unusual design features 
of the Alenia C-27J. It is not a rule of general applicability, and it 
affects only the applicant that applied to the FAA for approval of 
these features on the airplane.

Accordingly, the Administrator of the Federal Aviation Administration 
(FAA) proposes the following special conditions as part of the type-
certification basis for the C-27J.

1. Control of Electrical Power to the Lavatory Located in the Class E 
Cargo Compartment

    A means must be provided to shut off electrical power to the 
lavatory should smoke or fire be detected anywhere in the Class E cargo 
compartment, including in the lavatory. Two types of shut-off systems 
meet this requirement:
     A manual system, with an airplane flight manual (AFM) 
procedure to instruct the flight crew on where and how to shut off the 
power, or
     An automatic system that shuts off power to the lavatory 
following a lavatory or cargo-compartment smoke-detector alarm.

2. Control of the Oxygen-Delivery-System Flow to the Lavatory and Cargo 
Compartment

    A means must be provided to shut off oxygen flow to the lavatory 
should smoke or fire be detected anywhere in the Class E cargo 
compartment, including in the lavatory. Two types of shut-off systems 
meet this requirement:
     A manual system, with an AFM procedure to instruct the 
flight crew on where and how to shut off the oxygen flow, or
     An automatic system that shuts off oxygen flow to the 
lavatory following a lavatory or cargo-compartment smoke-detector 
alarm.
