Download as PDF sroberts on DSK5SPTVN1PROD with PROPOSALS Federal Register / Vol. 77, No. 180 / Monday, September 17, 2012 / Proposed Rules At the February 22, 2012, meeting, the Committee discussed the impact of the proposed changes on handlers and producers. The proposed action would be a relaxation of the current handling regulation, allowing an additional 30 days for industry participants to fully supply the market with the total amount of spearmint oil allotted under the volume regulation provisions of the order. The benefits of this rule are not expected to be disproportionately greater or less for small handlers or producers than for larger entities. The Committee discussed alternatives to these proposed changes, including making no changes at all, changing the dates but keeping them within the month of November, and extending the dates further into December or into January. The Committee thought that maintaining the dates in the current regulations would not be responsive to the changing production practices of the industry. In addition, they felt that the dates should be extended at least 30 days for the change to be meaningful. However, the Committee believed that extending the dates any further than the proposed dates would affect the Committee’s ability to establish accurate reports for the completed harvest season in a timely manner. The Committee members unanimously agreed that changing the dates for transferring, storing, and pooling excess oil from November 1 to December 1 addressed the industry’s current needs without negatively impacting the operation of the Committee. 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 necessary. Should any changes become necessary, they would be submitted to OMB for approval. This proposed rule would change the date by which excess oil must be transferred between producers to fill annual allotment deficiencies or delivered to the Committee or its designees for storage from November 1 to December 1. In addition, the rule would change the date the Committee must pool identified excess oil as reserve oil from November 1 to December 1. The rule would be a relaxation of the volume regulation provisions of the order. No changes in the reporting or recordkeeping requirements would be necessary as a result of this action. Accordingly, this VerDate Mar<15>2010 17:54 Sep 14, 2012 Jkt 226001 proposed rule would not impose any additional reporting or recordkeeping requirements on either small or large spearmint oil producers or 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. Furthermore, USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this proposed rule. AMS is committed to complying with the E-Government Act, to promote the use of the Internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. In addition, the Committee’s meeting was widely publicized throughout the 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 22, 2012, meeting was a public meeting and all entities, both large and small, were able to express views on this issue. Finally, interested persons are invited to submit comments on this proposed rule, including the regulatory and informational impacts of this action on small businesses. A small business guide on complying with fruit, vegetable, and specialty crop marketing agreements and orders may be viewed at: www.ams.usda.gov/ MarketingOrdersSmallBusinessGuide. Any questions about the compliance guide should be sent to Laurel May at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section. A 60-day comment period is provided to allow interested persons to respond to this proposed rule.

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). Background Novel or Unusual Design Features On May 14, 2009, Embraer S.A. applied for a type certificate for their new Model EMB–550 airplane. The Model EMB–550 airplane is the first of a new family of jet airplanes designed for corporate flight, fractional, charter, and private owner operations. The aircraft has a conventional configuration with low wing and T-tail empennage. The primary structure is metal with composite empennage and control surfaces. The Model EMB–550 airplane is designed for 8 passengers, with a maximum of 12 passengers. It is equipped with two Honeywell HTF7500–E medium bypass ratio turbofan engines mounted on aft fuselage pylons. Each engine produces approximately 6,540 pounds of thrust for normal takeoff. The primary flight controls consist of hydraulically powered fly-by-wire elevators, aileron and rudder, controlled by the pilot or copilot sidestick. The Model EMB–550 airplane will incorporate the following novel or unusual design features: The Embraer S.A. Model EMB–550 airplane will have a fly-by-wire electronic flight control system and no direct coupling from the flightdeck controller to the control surface. As a result, the pilot is not aware of the actual control surface position as envisioned when part 25 was written. Type Certification Basis Under the provisions of Title 14, Code of Federal Regulations (14 CFR) 21.17, Embraer S.A. must show that the Model EMB–550 airplane meets the applicable provisions of part 25, as amended by Amendments 25–1 through 25–127. 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 EMB–550 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. 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 Model EMB–550 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.’’ PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 Discussion This special condition proposes that the flightcrew receive a suitable flight control position annunciation when a flight condition exists in which nearly full surface authority (not crewcommanded) is being used. 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 function in both intended and unexpected control-limiting situations. As a result, they must be properly balanced between providing necessary crew awareness and being a potential nuisance to the flightcrew. A monitoring system that compares airplane motion and surface deflection with the demand of the pilot sidestick controller could help reduce nuisance alerting. This special condition also addresses flight control system mode annunciation. It proposes suitable mode annunciation be provided to the flightcrew for events that significantly change the operating mode of the system but do not merit the classic ‘‘failure warning.’’ This proposed special condition would establish a level of safety equivalent to that provided by a conventional flight control system and that contemplated in existing regulations. Applicability As discussed above, these special conditions are applicable to the Model EMB–550 airplane. Should Embraer S.A. 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. E:\FR\FM\17SEP1.SGM 17SEP1 Federal Register / Vol. 77, No. 180 / Monday, September 17, 2012 / Proposed Rules Conclusion ACTION: This action affects only certain novel or unusual design features on one model of airplanes.

The Proposed Special Conditions Accordingly, the Federal Aviation Administration (FAA) proposes the following special conditions as part of the type certification basis for Model EMB–550 airplanes. 1. Electronic Flight Control System: Control Surface Awareness and Mode Annunciation. In addition to the requirements of §§ 25.143, 25.671, and 25.672, the following requirements apply: a. 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 flightcrew are appropriately balanced between nuisance and that necessary for crew awareness. b. 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.

Background

    On May 14, 2009, Embraer S.A. applied for a type certificate for 
their new Model EMB-550 airplane. The Model EMB-550 airplane is the 
first of a new family of jet airplanes designed for corporate flight, 
fractional, charter, and private owner operations. The aircraft has a 
conventional configuration with low wing and T-tail empennage. The 
primary structure is metal with composite empennage and control 
surfaces. The Model EMB-550 airplane is designed for 8 passengers, with 
a maximum of 12 passengers. It is equipped with two Honeywell HTF7500-E 
medium bypass ratio turbofan engines mounted on aft fuselage pylons. 
Each engine produces approximately 6,540 pounds of thrust for normal 
takeoff. The primary flight controls consist of hydraulically powered 
fly-by-wire elevators, aileron and rudder, controlled by the pilot or 
copilot sidestick.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.17, Embraer S.A. must show that the Model EMB-550 airplane 
meets the applicable provisions of part 25, as amended by Amendments 
25-1 through 25-127.
    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 EMB-550 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 EMB-550 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 EMB-550 airplane will incorporate the following novel or 
unusual design features: The Embraer S.A. Model EMB-550 airplane will 
have a fly-by-wire electronic flight control system and no direct 
coupling from the flightdeck controller to the control surface. As a 
result, the pilot is not aware of the actual control surface position 
as envisioned when part 25 was written.

Discussion

    This special condition proposes that the flightcrew receive a 
suitable flight control position annunciation when a flight condition 
exists in which nearly full surface authority (not crew-commanded) is 
being used. 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 function in both intended 
and unexpected control-limiting situations. As a result, they must be 
properly balanced between providing necessary crew awareness and being 
a potential nuisance to the flightcrew. A monitoring system that 
compares airplane motion and surface deflection with the demand of the 
pilot sidestick controller could help reduce nuisance alerting.
    This special condition also addresses flight control system mode 
annunciation. It proposes suitable mode annunciation be provided to the 
flightcrew for events that significantly change the operating mode of 
the system but do not merit the classic ``failure warning.''
    This proposed special condition would establish a level of safety 
equivalent to that provided by a conventional flight control system and 
that contemplated in existing regulations.

Applicability

    As discussed above, these special conditions are applicable to the 
Model EMB-550 airplane. Should Embraer S.A. 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.

The Proposed Special Conditions

    Accordingly, the Federal Aviation Administration (FAA) proposes the 
following special conditions as part of the type certification basis 
for Model EMB-550 airplanes.
    1. Electronic Flight Control System: Control Surface Awareness and 
Mode Annunciation. In addition to the requirements of Sec. Sec.  
25.143, 25.671, and 25.672, the following requirements apply:
    a. 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 flightcrew are appropriately balanced between 
nuisance and that necessary for crew awareness.

    b. 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.
