If the final product also contains biobased content from intermediate ingredient or feedstock material that is not designated, the percentage by weight that these biobased ingredients represent of the total organic carbon content should be included in the calculation. (3) Complex assemblies. The biobased content of a complex assembly product, where the product has ‘‘n’’ components whose biobased and organic carbon content can be experimentally determined, will be calculated using the following equation: Where: Mi = mass of the nth component BCCi = biobased carbon content of the nth component (%) OCCi = organic carbon content of the nth component (%) (E917) and multi-attribute decision analysis (E1765), the British Standards Institution PAS 2050, and the National Institute of Standards and Technology BEES analytical tool. USDA will make such stakeholder-supplied information available on the BioPreferred Web site. (b) Performance test information. In assessing performance of qualified biobased products, USDA requires that procuring agencies rely on results of performance tests using applicable ASTM, ISO, Federal or military specifications, or other similarly authoritative industry test standards. Such testing must be conducted by a laboratory compliant with the requirements of the standards body. The procuring official will decide whether performance data must be brand-name specific in the case of products that are essentially of the same formulation. * * * * * DEPARTMENT OF TRANSPORTATION emcdonald on DSK67QTVN1PROD with RULES § 3201.8 Determining price, environmental and health benefits, and performance.

It features a twin-aisle, 9abreast, economy-class layout, and accommodates side-by-side placement of LD–3 containers in the cargo compartment. The basic Airbus Model A350–900 airplane configuration accommodates 315 passengers in a standard two-class arrangement. The design cruise speed is Mach 0.85 with a maximum take-off weight of 602,000 lbs. These special conditions for controlsurface awareness, applicable to Airbus Model A350–900 airplanes, require suitable flight-control-position annunciation and control-system mode of operation to be provided to the flightcrew when a flight condition exists in which nearly full surface authority (not crew-commanded) is being utilized. Suitability of such a display must take into account that some pilot-demanded maneuvers (e.g., rapid roll) are necessarily associated with intended full performance, which may saturate the surface. Therefore, simple alerting systems, which would function in both intended or unexpected control-limiting situations, must be properly balanced between needed crew awareness and nuisance features. A monitoring system that might compare airplane motion and surface deflection, and pilot side-stick controller (SSC) demand, could be useful for elimination of nuisance alerting. Type Certification Basis Under Title 14, Code of Federal Regulations (14 CFR) 21.17, Airbus must show that the Model A350–900 airplane meets the applicable provisions of 14 CFR part 25, as amended by Amendments 25–1 through 25–129. 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 A350–900 airplane because of a novel or unusual design feature, special conditions are prescribed under § 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 § 21.101. In addition to the applicable airworthiness regulations and special conditions, the Airbus Model A350–900 airplane must comply with the fuel-vent and exhaust-emission requirements of 14 CFR part 34 and the noisecertification requirements of 14 CFR part 36. The FAA must issue a finding VerDate Mar<15>2010 17:22 Jul 31, 2014 Jkt 232001 of regulatory adequacy under section 611 of Public Law 92–574, the ‘‘Noise Control Act of 1972.’’ The FAA issues special conditions, as defined in 14 CFR 11.19, under § 11.38, and they become part of the typecertification basis under § 21.17(a)(2). Novel or Unusual Design Features The Airbus Model A350–900 airplane incorporates the following novel or unusual design features: Electronic flight-control system providing controlsurface awareness and mode annunciation to the flightcrew. Discussion With a response-command type flightcontrol system and no direct coupling from cockpit controller to control surface, the pilot is not aware of actual surface position utilized to fulfill the requested demand. Some unusual flight conditions, arising from atmospheric conditions and/or airplane or engine failures, may result in full or nearly full surface deflection. Unless the flightcrew is made aware of excessive deflection or impending control-surface limiting, piloted or auto-flight system control of the airplane might be inadvertently continued in such a manner as to cause loss of control or other unsafe stability or performance characteristics. 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 authority citation for these special conditions is as follows: Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704. The Special Conditions Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for Airbus Model A350–900 airplanes. Current airworthiness standards do not contain adequate safety standards for the design. In addition to the requirements of §§ 25.143, 25.671 and 25.672, the following special conditions apply: 1. The system design must ensure that the flightcrew is made suitably aware whenever the primary control means nears the limit of control authority. Note: The term ‘‘suitably aware’’ indicates annunciations provided to the flight crew that are appropriately balanced between nuisance and necessary crew awareness. 2. If the design of the flight-control system has multiple modes of operation, a means must be provided to indicate to the crew any mode that significantly changes or degrades the normal handling or operational characteristics of the airplane.

SUPPLEMENTARY INFORMATION: 

Background

    On August 25, 2008, Airbus applied for a type certificate for their 
new Model A350-900 airplane. Later, Airbus requested and the FAA 
approved, an extension to the application for FAA type certification to 
November 15, 2009. The Model A350-900 airplane has a conventional 
layout with twin wing-mounted Rolls-Royce Trent XWB

engines. It features a twin-aisle, 9-abreast, economy-class layout, and 
accommodates side-by-side placement of LD-3 containers in the cargo 
compartment. The basic Airbus Model A350-900 airplane configuration 
accommodates 315 passengers in a standard two-class arrangement. The 
design cruise speed is Mach 0.85 with a maximum take-off weight of 
602,000 lbs.
    These special conditions for control-surface awareness, applicable 
to Airbus Model A350-900 airplanes, require suitable flight-control-
position annunciation and control-system mode of operation to be 
provided to the flightcrew when a flight condition exists in which 
nearly full surface authority (not crew-commanded) is being utilized. 
Suitability of such a display must take into account that some pilot-
demanded maneuvers (e.g., rapid roll) are necessarily associated with 
intended full performance, which may saturate the surface. Therefore, 
simple alerting systems, which would function in both intended or 
unexpected control-limiting situations, must be properly balanced 
between needed crew awareness and nuisance features. A monitoring 
system that might compare airplane motion and surface deflection, and 
pilot side-stick controller (SSC) demand, could be useful for 
elimination of nuisance alerting.

Type Certification Basis

    Under Title 14, Code of Federal Regulations (14 CFR) 21.17, Airbus 
must show that the Model A350-900 airplane meets the applicable 
provisions of 14 CFR part 25, as amended by Amendments 25-1 through 25-
129.
    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 A350-900 airplane because of 
a novel or unusual design feature, special conditions are prescribed 
under 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 Airbus Model A350-900 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. The FAA must issue 
a finding of regulatory adequacy under section 611 of Public Law 92-
574, the ``Noise Control Act of 1972.''
    The FAA issues special conditions, as defined in 14 CFR 11.19, 
under Sec.  11.38, and they become part of the type-certification basis 
under Sec.  21.17(a)(2).

Novel or Unusual Design Features

    The Airbus Model A350-900 airplane incorporates the following novel 
or unusual design features: Electronic flight-control system providing 
control-surface awareness and mode annunciation to the flightcrew.

Discussion

    With a response-command type flight-control system and no direct 
coupling from cockpit controller to control surface, the pilot is not 
aware of actual surface position utilized to fulfill the requested 
demand. Some unusual flight conditions, arising from atmospheric 
conditions and/or airplane or engine failures, may result in full or 
nearly full surface deflection. Unless the flightcrew is made aware of 
excessive deflection or impending control-surface limiting, piloted or 
auto-flight system control of the airplane might be inadvertently 
continued in such a manner as to cause loss of control or other unsafe 
stability or performance characteristics.
    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. 25-13-15-SC for Airbus 
Model A350-900 airplanes was published in the Federal Register on 
December 17, 2013 (78 FR 76254). No comments were received, and the 
special conditions are adopted as proposed.

Applicability

    As discussed above, these special conditions apply to Airbus Model 
A350-900 airplanes. Should Airbus apply later 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 the Airbus Model A350-900 airplanes. It is not a rule of general 
applicability.
