product and summing the results (if 

more than one designated intermediate 

ingredient or feedstock is used). 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 (%) 

(d) Products and intermediate 

ingredients or feedstocks with the same 

formulation. In the case of products and 

intermediate ingredients or feedstocks 

that are essentially the same 

formulation, but marketed under more 

than one brand name, biobased content 

test data need not be brand-name 

specific. 

■ 9. Section 3201.8 is amended by 

revising the section heading and by 

revising paragraphs (a) and (b) to read 

as follows: 

§ 3201.8 Determining price, environmental 

and health benefits, and performance. 

(a) Providing information on price 

and environmental and health benefits. 

Federal agencies may not require 

manufacturers or vendors of qualified 

biobased products to provide to 

procuring agencies more data than 

would be required of other 

manufacturers or vendors offering 

products for sale to a procuring agency 

(aside from data confirming the 

biobased contents of the products) as a 

condition of the purchase of biobased 

products from the manufacturer or 

vendor. USDA will work with 

manufacturers and vendors to collect 

information needed to estimate the price 

of biobased products, complex 

assemblies, intermediate materials or 

feedstocks as part of the designation 

process, including application units, 

average unit cost, and application 

frequency. USDA encourages industry 

stakeholders to provide information on 

environmental and public health 

benefits based on industry accepted 

analytical approaches including, but not 

limited to: Material carbon footprint 

analysis, the ASTM D7075 standard for 

evaluating and reporting on 

environmental performance of biobased 

products, the International Standards 

Organization ISO 14040, the ASTM 

International life-cycle cost method 

(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.

Special Conditions: Airbus Model 

A350–900 Airplane; Control-Surface 

Awareness and Mode Annunciation 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final special conditions. 

SUMMARY: These special conditions are 

issued for Airbus Model A350–900 

airplanes. These airplanes have a novel 

or unusual design feature associated 

with control-surface awareness and 

mode annunciation provided by the 

electronic flight-control system. The 

applicable airworthiness regulations do 

not contain adequate or appropriate 

safety standards for this design feature. 

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. 

DATES: Effective Date: September 2, 

2014.

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 wingmounted Rolls-Royce Trent XWB

44658 Federal Register / Vol. 79, No. 148 / Friday, August 1, 2014 / Rules and Regulations 

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 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 

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. 

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.

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.
