Finally, the proposal was made available through the Internet by USDA and the Office of the Federal Register. A 60-day comment period ending August 7, 2007, was provided for interested persons to respond to the proposal. One comment was received during the comment period in response to the proposal. The commenter asked if the same rules and safeguards apply to almonds imported from other countries. Almonds are not listed in section 8e of Act. Thus, imported almonds are not subject to comparable quality requirements as those in effect for the domestic commodity. Accordingly, no changes will be made to the rule as proposed, based on the comment received. A small business guide on complying with fruit, vegetable, and specialty crop marketing agreements and orders may be viewed at: https://www.ams.usda.gov/ fv/moab.html. Any questions about the compliance guide should be sent to Jay Guerber at the previously mentioned address in the FOR FURTHER INFORMATION CONTACT section. After consideration of all relevant matters presented, including the information and recommendation submitted by the Board and other available information, it is hereby found that this rule, as hereinafter set forth, will tend to effectuate the declared policy of the Act. It is further found that good cause exists for not postponing the effective date of this rule until 30 days after publication in the Federal Register (5 U.S.C. 553) because mandatory compliance with the Salmonella treatment program began September 1, 2007, and this rule should be in place as soon as possible so the Board can track treated and untreated almonds. Further, handlers are aware of this action, which was unanimously recommended at a public meeting. Also, a 60-day comment period was provided for in the proposed rule, and the comment received was addressed herein. jlentini on PROD1PC65 with RULES List of Subjects in 7 CFR Part 981 Almonds, Marketing agreements, Nuts, Reporting and recordkeeping requirements.

Background On November 11, 2003, Malibu Power & Propeller Int’l, LLC applied for a supplemental type certificate for the Piper Models PA–46–310P and PA–46– 350P to install a full authority digital engine control in the Piper Models PA– 46–310P and PA–46–350P. The Piper Models PA–46–310P and PA–46–350P, currently approved under Type Certificate No. A25SO, are six-place, pressurized, turbocharged, single-engine airplanes. Malibu Power & Propeller Int’l, LLC plans to use an electronic engine control instead of a traditional mechanical control system on the Piper Model PA–46–310P (Malibu) and PA– 46–350P (Malibu Mirage) airplane. The electronic engine control system performs critical functions, such as the control of the ignition and fuel injection functions, throughout the operational envelope. Type Certification Basis jlentini on PROD1PC65 with RULES Under the provisions of § 21.101, Malibu Power & Propeller Int’l, LLC must show that the Piper Models PA– 46–310P and PA–46–350P, as changed, continue to meet the applicable provisions of the regulations incorporated by reference in Type Certificate No. A25SO, or the applicable regulations in effect on the date of application for the change. The regulations incorporated by reference in the type certificate are commonly referred to as the ‘‘original type certification basis.’’ The regulations incorporated by reference in Type Certificate No. A25SO are as follows: PA–46–310P and PA–46–350P: 14 CFR part 23, effective February 1, 1965, as amended by Amendment 23–25, effective March 6, 1980; 14 CFR part 25, § 25.783(e) as amended by Amendment 25–54, effective October 14, 1980; § 25.831(c) and (d) as amended by Amendment 25– 41, effective September 1, 1977; and 14 CFR part 36, Appendix F VerDate Aug<31>2005 16:11 Sep 11, 2007 Jkt 211001 through Amendment 36–15, effective May 6, 1988, when equipped with 2 blade propeller or part 36, Appendix G through Amendment 36–16, effective December 18, 1988, when equipped with optional 3 blade propeller.

Eligible Serial Numbers: 4636375 and up. Discussion If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 23, § 23.1309) do not contain adequate or appropriate safety standards for the Piper Models PA–46– 310P and PA–46–350P because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 51993 In addition to the applicable airworthiness regulations and special conditions, the Piper Models PA–46– 310P and PA–46–350P 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 appropriate, as defined in § 11.19, as required by § 11.38 and they become part of the type certification basis under § 21.101. The Malibu Power & Propeller Int’l, LLC modified Piper Model PA–46–310P and PA–46–350P airplanes will incorporate a novel or unusual design feature, an engine that includes a digital electronic engine control system with FADEC capability. The control system will be certificated as part of the engine. However, the installation of an engine with an electronic control system requires evaluation due to the possible effects on or by other airplane systems (e.g., radio interference with other airplane electronic systems, shared engine and airplane power sources). The regulatory requirements in 14 CFR part 23 for evaluating the installation of complex systems, including electronic systems, are contained in § 23.1309. However, when § 23.1309 was developed, the use of electronic control systems for engines was not envisioned; therefore, the § 23.1309 requirements were not applicable to systems certificated as part of the engine (reference § 23.1309(f)(1)). Electronic control systems often require inputs from airplane data and power sources and outputs to other airplane systems (e.g., automated cockpit powerplant controls such as mixture setting). The parts of the system that are not certificated with the engine could be evaluated using the criteria of § 23.1309. However, the integral nature of systems such as these makes it unfeasible to evaluate the airplane portion of the system without including the engine portion of the system. Section 23.1309(f)(1) prevents complete evaluation of the installed airplane system since evaluation of the engine system’s effects is not required. Therefore, special conditions are proposed for the Malibu Power & Propeller Int’l, LLC modified Piper Model PA–46–310P and PA–46–350P airplanes to evaluate the installation of the electronic engine control system for compliance with the requirements of § 23.1309(a) through (e) at Amendment 23–49. E:\FR\FM\12SER1.SGM 12SER1 51994 Federal Register / Vol. 72, No. 176 / Wednesday, September 12, 2007 / Rules and Regulations Novel or Unusual Design Features The Malibu Power & Propeller Int’l, LLC modified Piper Models PA–46– 310P and PA–46–350P will incorporate the following novel or unusual design features: The Malibu Power & Propeller Int’l, LLC modified Piper Models PA– 46–310P and PA–46–350P will incorporate a digital electronic engine control system. Applicability Special conditions are initially applicable to the model for which they are issued. Should the applicant apply for a supplemental type certificate to modify any other model included on the same type certificate to incorporate the same novel or unusual design feature, the special conditions would also apply to the other model under the provisions of § 21.101(a)(1). Conclusion This action affects only certain novel or unusual design features on one model of airplane. It is not a rule of general applicability and affects only the applicant who applied to the FAA for approval of these features on the airplane. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, because a delay would significantly affect the certification of the airplane, which is imminent, the FAA has determined that prior public notice and comment are unnecessary and impracticable, and good cause exists for adopting these special conditions upon issuance. The FAA is requesting comments to allow interested persons to submit views that may not have been submitted in response to the prior opportunities for comment described above.

PA-46-350P, currently approved under Type Certificate No. A25SO, are 
six-place, pressurized, turbocharged, single-engine airplanes. Malibu 
Power & Propeller Int'l, LLC plans to use an electronic engine control 
instead of a traditional mechanical control system on the Piper Model 
PA-46-310P (Malibu) and PA-46-350P (Malibu Mirage) airplane. The 
electronic engine control system performs critical functions, such as 
the control of the ignition and fuel injection functions, throughout 
the operational envelope.

Discussion

    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 23, Sec.  23.1309) do not contain 
adequate or appropriate safety standards for the Piper Models PA-46-
310P and PA-46-350P because of a novel or unusual design feature, 
special conditions are prescribed under the provisions of Sec.  21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the Piper Models PA-46-310P and PA-46-350P 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 appropriate, as defined in 
Sec.  11.19, as required by Sec.  11.38 and they become part of the 
type certification basis under Sec.  21.101.
    The Malibu Power & Propeller Int'l, LLC modified Piper Model PA-46-
310P and PA-46-350P airplanes will incorporate a novel or unusual 
design feature, an engine that includes a digital electronic engine 
control system with FADEC capability. The control system will be 
certificated as part of the engine. However, the installation of an 
engine with an electronic control system requires evaluation due to the 
possible effects on or by other airplane systems (e.g., radio 
interference with other airplane electronic systems, shared engine and 
airplane power sources). The regulatory requirements in 14 CFR part 23 
for evaluating the installation of complex systems, including 
electronic systems, are contained in Sec.  23.1309. However, when Sec.  
23.1309 was developed, the use of electronic control systems for 
engines was not envisioned; therefore, the Sec.  23.1309 requirements 
were not applicable to systems certificated as part of the engine 
(reference Sec.  23.1309(f)(1)).
    Electronic control systems often require inputs from airplane data 
and power sources and outputs to other airplane systems (e.g., 
automated cockpit powerplant controls such as mixture setting). The 
parts of the system that are not certificated with the engine could be 
evaluated using the criteria of Sec.  23.1309. However, the integral 
nature of systems such as these makes it unfeasible to evaluate the 
airplane portion of the system without including the engine portion of 
the system. Section 23.1309(f)(1) prevents complete evaluation of the 
installed airplane system since evaluation of the engine system's 
effects is not required.
    Therefore, special conditions are proposed for the Malibu Power & 
Propeller Int'l, LLC modified Piper Model PA-46-310P and PA-46-350P 
airplanes to evaluate the installation of the electronic engine control 
system for compliance with the requirements of Sec.  23.1309(a) through 
(e) at Amendment 23-49.

Novel or Unusual Design Features

    The Malibu Power & Propeller Int'l, LLC modified Piper Models PA-
46-310P and PA-46-350P will incorporate the following novel or unusual 
design features: The Malibu Power & Propeller Int'l, LLC modified Piper 
Models PA-46-310P and PA-46-350P will incorporate a digital electronic 
engine control system.

Applicability

    Special conditions are initially applicable to the model for which 
they are issued. Should the applicant apply for a supplemental type 
certificate to modify any other model included on the same type 
certificate to incorporate the same novel or unusual design feature, 
the special conditions would also apply to the other model under the 
provisions of Sec.  21.101(a)(1).

Conclusion

    This action affects only certain novel or unusual design features 
on one model of airplane. It is not a rule of general applicability and 
affects only the applicant who applied to the FAA for approval of these 
features on the airplane.
    The substance of these special conditions has been subjected to the 
notice and comment period in several prior instances and has been 
derived without substantive change from those previously issued. It is 
unlikely that prior public comment would result in a significant change 
from the substance contained herein. Therefore, because a delay would 
significantly affect the certification of the airplane, which is 
imminent, the FAA has determined that prior public notice and comment 
are unnecessary and impracticable, and good cause exists for adopting 
these special conditions upon issuance. The FAA is requesting comments 
to allow interested persons to submit views that may not have been 
submitted in response to the prior opportunities for comment described 
above.

List of Subjects in 14 CFR Part 23

    Aircraft, Aviation safety, Signs and symbols.

Citation

    The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 106(g), 40113 and 44701; 14 CFR 21.16 and 
21.101; and 14 CFR 11.38 and 11.19.

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 the Malibu Power & Propeller Int'l, 
LLC modified Piper Model PA-46-310P and PA-46-350P airplanes.
    The installation of the electronic engine control system must 
comply with the requirements of Sec.  23.1309(a) through (e) at 
Amendment 23-49. The intent of this requirement is not to reevaluate 
the inherent hardware reliability of the control itself, but rather 
determine the effects, including environmental effects addressed in 
Sec.  23.1309(e), on the airplane systems and engine control system 
when installing the control on the airplane. When appropriate, engine 
certification data may be used when showing compliance with this 
requirement; however, the effects of the installation on this data must 
be addressed.

    Issued in Kansas City, Missouri on September 5, 2007.

Manager, Small Airplane Directorate, Aircraft Certification Service.
