Download as PDF rmajette on DSK2TPTVN1PROD with RULES 43232 Federal Register / Vol. 79, No. 143 / Friday, July 25, 2014 / Rules and Regulations This rule continues in effect the action that decreased the assessment rate established for the Committee and collected from handlers for the 2014– 2015 and subsequent marketing years from $0.10 to $0.09 per pound of spearmint oil handled. The Committee unanimously recommended 2014–2015 expenditures of $266,400 and an assessment rate of $0.09. The assessment rate of $0.09 is $0.01 lower than the rate previously in effect. The quantity of assessable spearmint oil for the 2014–15 marketing year is estimated at 2,500,000 pounds. Thus, the $0.09 rate should provide $225,000 in assessment income. Income derived from handler assessments, along with interest income and funds from the Committee’s monetary reserve will be adequate to cover the budgeted expenses. This action will allow the Committee to reduce its financial reserve while still providing adequate funding to meet program expenses. This rule continues in effect the action that decreased the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers, and some of the costs may be passed on to producers. However, decreasing the assessment rate reduces the burden on handlers, and may reduce the burden on producers. Additionally, the Committee’s meeting was widely publicized throughout the Far West spearmint oil industry and all interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the February 19, 2014, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35), the order’s information collection requirements have been previously approved by the Office of Management and Budget (OMB) and assigned OMB No. 0581–0178, Vegetable and Specialty Crops. No changes in those requirements as a result of this action are anticipated. Should any changes become necessary, they would be submitted to OMB for approval. This action imposes no additional reporting or recordkeeping requirements on either small or large Far West spearmint oil handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. VerDate Mar<15>2010 15:26 Jul 24, 2014 Jkt 232001 USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. Comments on the interim rule were required to be received on or before June 23, 2014. No comments were received. Therefore, for the reasons given in the interim rule, we are adopting the interim rule as a final rule, without change. To view the interim rule, go to: https:// www.regulations.gov/ #!documentDetail;D=AMS-FV-14-00270001. This action also affirms information contained in the interim rule concerning Executive Orders 12866, 13563, 12988, and 13175; the Paperwork Reduction Act (44 U.S.C. Chapter 35); and the E-Gov Act (44 U.S.C. 101). After consideration of all relevant material presented, including the information and recommendation submitted by the Committee and other available information, it is found that finalizing the interim rule, without change, as published in the Federal Register (79 FR 22359, April 22, 2014) will tend to effectuate the declared policy of the Act.

SUPPLEMENTARY INFORMATION: SUMMARY: Background On February 9, 2009, Learjet Inc. applied for a type certificate for their new Model LJ–200–1A10 airplane (hereafter referred to as the ‘‘Model LJ– 200’’). The Model LJ–200 is a business class airplane powered by two highbypass turbine engines with an estimated maximum takeoff weight of 35,550 pounds and an interior configuration for up to 10 passengers.

If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the Model LJ–200 airplane because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. Special conditions are initially applicable to the model for which they are issued.

In addition to the applicable airworthiness regulations and special conditions, the Model LJ–200 airplane 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). wing, fuselage skin, stringers, spars, and most other structural elements of all major sub-assemblies of the airplane. Despite the major change from aluminum to composite material for the fuselage, the Model LJ–200 airplane must have in-flight survivability such that the composite fuselage does not propagate a fire. A methodology for assessing the in-flight fire survivability of an all-composite fuselage is therefore needed. The FAA believes that one way to assess the survivability within the cabin of the Model LJ–200 airplane is to conduct large-scale tests. These largescale tests would use a mock-up of a Model LJ–200 airplane fuselage skin/ structure section of sufficient size to assess any tendency for fire propagation. The fire threat used to represent the realistic ignition source in the airplane would consist of a 4″ x 4″ x 9″ polyurethane foam block and 10 ml of Heptane. This ignition source provides approximately three minutes of flame time and would be positioned at various points and orientations within the mocked up installation to impinge on those areas of the fuselage considered to be most crucial. This fire threat was established based on an assessment of a range of potential ignition sources, coupled with possible contamination of materials. The FAA considers this a severe fire threat, encompassing a variety of scenarios. However, should ignition or fire sources of a greater severity be identified, these special conditions or the method of compliance would need to be modified in order to take the more severe threat into account. Despite the major change from aluminum to composite material for the fuselage, the Model LJ–200 must have in-flight fire survivability such that the composite fuselage is no worse than that of a similar aluminum structure. 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.

SUPPLEMENTARY INFORMATION:

Background

    On February 9, 2009, Learjet Inc. applied for a type certificate 
for their new Model LJ-200-1A10 airplane (hereafter referred to as the 
``Model LJ-200''). The Model LJ-200 is a business class airplane 
powered by two high-bypass turbine engines with an estimated maximum 
takeoff weight of 35,550 pounds and an interior configuration for up to 
10 passengers.
    The Model LJ-200 is the first composite fuselage airplane design 
manufactured by Learjet Inc. A fuselage manufactured from composite 
material is considered a novel or unusual design with respect to 
existing regulations for this type of aircraft. The performance of 
aircraft consisting of a conventional

[[Page 43233]]

aluminum fuselage in an inaccessible in-flight fire scenario is 
understood based on service history and extensive intermediate and 
large-scale fire testing. The fuselage itself does not contribute to 
in-flight fire propagation. This may not be the case for an all-
composite fuselage. The existing regulations do not adequately address 
protection against an in-flight fire for an all-composite fuselage. 
These special conditions are necessary to ensure a level of safety 
equivalent to that provided by existing regulations.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.17, Learjet Inc. must show that the Model LJ-200 airplane meets 
the applicable provisions of part 25, as amended by Amendments 25-1 
through 25-127, and 14 CFR part 26, as amended by Amendment 26-1 
through 26-2.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 25) do not contain adequate or 
appropriate safety standards for the Model LJ-200 airplane because of a 
novel or unusual design feature, special conditions are prescribed 
under the provisions of Sec.  21.16.
    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 would also 
apply to the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the Model LJ-200 airplane 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).

Novel or Unusual Design Features

    The Model LJ-200 airplane will incorporate the following novel or 
unusual design features: The fuselage will be fabricated using 
composite materials instead of conventional aluminum.

Discussion

    The Model LJ-200 airplane will make extensive use of composite 
materials in the fabrication of the majority of the wing, fuselage 
skin, stringers, spars, and most other structural elements of all major 
sub-assemblies of the airplane. Despite the major change from aluminum 
to composite material for the fuselage, the Model LJ-200 airplane must 
have in-flight survivability such that the composite fuselage does not 
propagate a fire. A methodology for assessing the in-flight fire 
survivability of an all-composite fuselage is therefore needed.
    The FAA believes that one way to assess the survivability within 
the cabin of the Model LJ-200 airplane is to conduct large-scale tests. 
These large-scale tests would use a mock-up of a Model LJ-200 airplane 
fuselage skin/structure section of sufficient size to assess any 
tendency for fire propagation. The fire threat used to represent the 
realistic ignition source in the airplane would consist of a 4'' x 4'' 
x 9'' polyurethane foam block and 10 ml of Heptane. This ignition 
source provides approximately three minutes of flame time and would be 
positioned at various points and orientations within the mocked up 
installation to impinge on those areas of the fuselage considered to be 
most crucial.
    This fire threat was established based on an assessment of a range 
of potential ignition sources, coupled with possible contamination of 
materials. The FAA considers this a severe fire threat, encompassing a 
variety of scenarios. However, should ignition or fire sources of a 
greater severity be identified, these special conditions or the method 
of compliance would need to be modified in order to take the more 
severe threat into account.
    Despite the major change from aluminum to composite material for 
the fuselage, the Model LJ-200 must have in-flight fire survivability 
such that the composite fuselage is no worse than that of a similar 
aluminum structure.
    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.

Discussion of Comments

    Notice of proposed special conditions No. 25-14-01-SC for the 
Learjet Inc. Model LJ-200-1A10 airplane was published in the Federal 
Register on February 7, 2014 (79 FR 7406). No comments were received, 
and the special conditions are adopted as proposed.

Applicability

    As discussed above, these special conditions are applicable to the 
Model LJ-200 airplane. Should Learjet Inc. apply at a later date for a 
change to the type certificate to include another model incorporating 
the same novel or unusual design feature, the special conditions would 
apply to that model as well.

Conclusion

    This action affects only certain novel or unusual design features 
on one model of airplanes. It is not a rule of general applicability.
