### Federal Register/Vol. 72, No. 91 /Friday, May 11, 2007/Rules and Regulations

Affected ADs

(b)None. Applicability

(c)This AD applies to Model 750XL airplanes, serial numbers 125, 126, and 127, certificated in any category. Subject

(d) Air Transport Association ofAmerica (ATA) Code 22: Autopilot.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

* * * failure ofthe Autopilot System Computer resulting in the possibility ofan outof trim condition, which may lead to loss ofaircraft control* * *

Actions and Compliance

(f) Unless already done, do the following actions before further flight.

(1)Modify the autopilotpitch trim circuit with additional protective features following Pacific Aerospace Limited Mandatory ServicE Bulletin PACSB/XL/025, dated March 5, 2007.

(2) Inspect the Pitch Servo to confirm part number (P/N) 108-15-Pl is installed following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/XL/025, dated March 5, 2007.

(i) IfPitch Servo P/N 108-15-Pi is installed, no further action isnecessary.

(ii) IfPitch Servo P/N 108-15-Pl is not installed, replace the Pitch Servo withP/N 108-15-P1 following Pacific Aerospace Limited Mandatory Service Bulletin PACSB/ XL/025, dated March 5, 2007.

FAA ADDifferences

Note:This AD differs from the MCAI and/

or service information as follows:

(1)The MCAI requires an interim action of disconnecting the autopilot following Pacific Aerospace Limited Alert Service Bulletin PACSB/XL/001, dated February 16, 2007. Since there are no products of thistype currently registered in the United States, and Pacific Aerospace Limited Mandatory Servici Bulletin PACSB/XL/025, dated March 5, 2007, supersedes Pacific Aerospace Limited Alert Service Bulletin PACSB/XL001, dated February 16, 2007, we arenot requiring disconnection ofthe autopilot.Instead we require the autopilot comply with the terminating actions inPacific Aerospace Limited Mandatory Service Bulletin PACSB/ XL/025, dated March 5, 2007.

(2) The MCAI allows modification ofthe pitch trim circuit within 150 hours time-inservice. Since there areno products ofthis type currently registered inthe United States

we are requiring modification ofthe pitch trim circuitbefore a domestic airworthiness certificate can be issued,

Other FAA AD Provisions

### 26718

HeinOnline -- 72 Fed. Reg. 26718 2007Federal Register/Vol. 72, No. 91/Friday, May 11, 2007/ Rules and Regulations

I. ProposedAction

OnFebruary 14, 2007 (72 FR 6986),

we proposed to approve the 2005 Carbon Monoxide Redesignation Request and Carbon Monoxide Maintenance Plan for the South Coast Air Basin (Maintenance Plan) as meeting the requirements ofCAA sections 107(d)(3)(E) and 175A. We also proposed to approve and find adequate the motorvehicle emissions budgets (MVEBs) submitted with the Maintenance Plan.

We proposed to approve the requbst by the State ofCalifornia toredesignate the area to attainment for CO under the provisions ofCAA section 107(d)(3)(E). Section 107(d)(3)(E) authorizes the EPA Administrator to redesignate areas to attainment ifthe area has attained the NAAQS due to permanent and enforceable emission reductions, and the approved SIP for the area meets all ofthe applicable requirements ofCAA section 110 (basicrequirements applicable to SIPs generally), PartD (special SIP requirements applicable to nonattainment areas), and 175A (SIP requirements for maintenance areas).

As partofour proposed determination that California has met applicable Part D provisions, -weproposed to adapt to CO nonattainment areas the provisions ofour Clean DataPolicy, which was initially established for ozone (see discussion at 72 FR 6989). Under the Clean DataPolicy, certain CAA PartD requirements-including the requirements for developing attainment demonstrations, reasonable further progress (RFP) plans,reasonably available control measures (RACM) and contingency measures-no longer apply because the area has already attained the NAAQS.

Finally, because our interim approval ofCalifornia's I/Mprogram for CO in the South Coast expired on August 7, 1998, California submitted a demonstration that the I/Mprogram meetsthe low-enhanced requirements applicable to the South Coast CO nonattainment area (see discussion in section III.B.4. We proposed to approve that demonstration.
U. PublicComments

.Our February 14, 2007 proposed rule provided a 30-daypublic comment period, which closed on March 16, 2007. We received no comments on our proposal during thisperiod.
III. Final Action

We are takingfinal action to redesignate the South Coast from nonattainment to attainment for the CO, National Ambient AirQuality Standards; (NAAQS) under CAA section 107(d)(3)(E).

We are approving the following SIP revision as meeting the Clean AirAct (CAA) requirements formaintenance plans for carbon monoxide (CO) under CAA section 175A: 2005 Carbon MonoxideRedesignationRequestand CarbonMonoxideMaintenancePlan for theSouth Coast AirBasin,adopted by the SCAQMD on March 4, 2005, and adopted and submittedby the CARB on February 24, 2006.1

We are approving Appendix V, page V-5-4, Table 5-2-"Carbon Monoxide Emissions (tons/day)Projected from 1993 through 2000 forthe South Coast Air Basin," in the 1997COPlan forthe Sou'th Coast,adopted by SCAQMD on November 15, 1996, and adopted and submitted by CARB on February 5, 1997, as meeting the requirements of CAA section 187(b)(2) relating to transportation control measures to offset emissions associated with growth in vehicle miles traveled and vehicle trips.

We are finding adequate and approving under CAA section 176(c) the following motor vehicle emission budgets included inthe maintenance plan: 2888 tons per day ofCO for 2005, and 2137 tonsper day of COfor 2010, 2015, and 2020.

We are approving the State's demonstration that the California motor vehicle inspection and maintenance (I/M)program meets the lowenhanced I/Mrequirements for CO in the South Coast under CAA section 187(a)(6). The State's I/Mprogram submittal ofJanuary 22, 1996, remains an approved part of the SIP, following its approval on January 8, 1997 (62 FR 1150).
IV. Statutory andExecutive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is nota "significant regulatory action" and therefore is not subject to review by the Office ofManagement and Budget. For thisreason, this action is also not subject to Executive Order 13211, (Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, orUse" (66 FR 28355, May 22, 2001). This action merely approves changes to state law asmeeting Federal requirements, and imposes no additional requirements beyond those imposed bystate law. Accordingly, the Administrator certifies that this rule will not have asignificant economic impact on a substantial number ofsmall

' A letterfrom CARB dated August 11, 2006, contained information related to the enhancedI/M progrhni, butwe &ehotinc6rporating thig letter in the.approved SIP. -, "', , . ..!,,,entities under the Regulatory Flexibility Act (5U.S.C. 601 etseq.). Because this rule approves pre-existing requirements under state law and does notimpose any additional enforceable dutybeyond that required by state law, it does not contain any unfunded mandate or significantly oruniquely affect small governments, as described inthe Unfunded Mandates Reform Actof 1995 (Pub.L. 104-4).

This rule also does not have tribal implications because it will not have a substantial direct effect onone or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsilfilities between the Federal Government and Indian tribes,

as specified byExecutive Order 13175 (65FR 97249, November 9, 2000), nor will ithave substantial direct effects on the States, on therelationship between the national government and the States,

or on the distribution ofpower and responsibilities among the various levels ofgovernment, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999), because itmerely approves aState ruleimplementing a Federal standard, and does notalter the relationship orthe distribution ofpower and responsibilities established in the CAA. This rule also is not subject to Executive Order 13045 "Protection of Children from Environmental Health Risks and Safety Risks" (62 FR 19885, April 23, 1997), because it approves a stateplan implementing a Federal Standard.

In reviewing SIPsubmissions, EPA's role is to approve state choices, provided thatthey meet the criteria of the Clean AirAct. Inthis context, in the absence ofa prior existing requirement forthe state to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. Itwould thusbe inconsistent with applicable law for EPA, when itreviews a SIP, to use VCS inplace of a SIP submission that otherwise satisfies the provisions ofthe Clean AirAct. Thus, the requirements of section 12(d) ofthe National Technology Transfer and Advancement Actof 1995 (15 U.S.C. 272 note) do not apply.

The Congressional Review Act, 5 U.S.C. 801 etseq., as.addedby the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rulereport, which includes a copy ofthe rule, to each House ofthe Congress and to the Comptroller General ofthe United States. EPA will submit a report containing this rule and other

required information to the U.S. Senate, the U.S. House ofRepresentatives, and theComptroller General ofthe United States prior to publication ofthe rule in the Federal Register. A majorrule cannot take effect until 60 days after it is published inthe Federal Register. This action is nota majorrule as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) ofthe Clean Air Act, petitions forjudicial review of this action mustbe filed in the United States Court ofAppeals for the appropriate circuit byJuly 10, 2007. Filing apetition forreconsideration by the Administrator ofthis final rule does notaffect the finality ofthis rule forthe purposes ofjudicial review nor does it extend the time within which a petition forjudicial review may be filed, and shall notpostpone the effectiveness of such rule oraction. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
