comprehensive criteria are needed for 

the new generation of high-bypass 

engines. The special conditions would 

distinguish between the more common 

engine-failure events and those rare 

events resulting from structural failures. 

The more-common events would 

continue to be treated as static torque 

limit load conditions. The more-severe 

events resulting from extreme enginefailure conditions (such as loss of a full 

fan blade at redline speed), would be 

treated as full dynamic-load conditions. 

These would be considered ultimate 

loads, and include all transient loads 

associated with the event. An additional 

safety factor would be applied to the 

more-critical airframe supporting 

structure. 

Applicability 

As discussed above, these special 

conditions are applicable to the Model 

EMB–550 airplane. Should Embraer 

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 airplane. 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 the Embraer 

Model EMB–550 airplane. 

In lieu of 14 CFR 25.361(b), the 

following special conditions apply: 

1. For turbine-engine installations, the 

engine mounts, pylons, and adjacent 

supporting airframe structure must be 

designed to withstand 1g level flight 

loads acting simultaneously with the 

maximum limit torque loads imposed 

by each of the following: 

(a) Sudden engine deceleration due to 

a malfunction, which could result in a 

temporary loss of power or thrust, and 

(b) The maximum acceleration of the 

engine. 

2. For auxiliary power unit (APU) 

installations, the APU mounts and 

adjacent supporting airframe structure 

must be designed to withstand 1g level 

flight loads acting simultaneously with 

the maximum limit torque loads 

imposed by each of the following: 

(a) Sudden APU deceleration due to 

malfunction or structural failure; and 

(b) The maximum acceleration of the 

APU. 

3. For engine-supporting structure, an 

ultimate loading condition must be 

considered that combines 1g flight loads 

with the transient dynamic loads 

resulting from: 

(a) The loss of any fan, compressor, or 

turbine blade; and separately 

(b) Where applicable to a specific 

engine design, any other engine 

structural failure that results in higher 

loads. 

4. The ultimate loads developed from 

the conditions specified in paragraphs 

3(a) and 3(b) of these special conditions 

are to be multiplied by a factor of 1.0 

when applied to engine mounts and 

pylons, and multiplied by a factor of 

1.25 when applied to adjacent 

supporting airframe structure. 

5. Any permanent deformation that 

results from the conditions specified in 

paragraph 3 of these special conditions 

must not prevent continued safe flight 

and landing.

Amendment of Class E Airspace; 

Worthington, MN 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action amends Class E 

airspace at Worthington, MN. 

Additional controlled airspace is 

necessary to accommodate new Area 

Navigation (RNAV) Standard Instrument 

Approach Procedures at Worthington 

Municipal Airport. This action 

enhances the safety and management of 

Instrument Flight Rule (IFR) operations 

at the airport. Geographic coordinates of 

the airport are also updated. 

DATES: Effective date: 0901 UTC, 

October 17, 2013. The Director of the 

Federal Register approves this 

incorporation by reference action under 

1 CFR Part 51, subject to the annual 

revision of FAA Order 7400.9 and 

publication of conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

On March 26, 2013, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to amend Class E airspace for the 

Worthington, MN, area, creating 

additional controlled airspace at 

Worthington Municipal Airport (78 FR 

18263) Docket No. FAA–2012–1139. 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. Class E airspace 

designations are published in paragraph 

6005 of FAA Order 7400.9W dated 

August 8, 2012, and effective September 

15, 2012, which is incorporated by 

reference in 14 CFR 71.1. The Class E 

airspace designations listed in this 

document will be published 

subsequently in the Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

amending Class E airspace extending 

upward from 700 feet above the surface 

to ensure that required controlled 

airspace exists from the current 7-mile 

radius of the airport to 11.6 miles north 

and 11.1 miles south of the airport to 

contain aircraft executing new standard 

instrument approach procedures at 

Worthington Municipal Airport, 

Worthington, MN. This action enhances 

the safety and management of IFR 

operations at the airport. Geographic 

coordinates of the airport are updated to 

coincide with the FAA’s aeronautical 

database. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated

impact is so minimal. Since this is a 

routine matter that only affects air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, does not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the U.S. Code. Subtitle 1, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the agency’s 

authority. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it amends 

controlled airspace at Worthington 

Municipal Airport, Worthington, MN. 

Environmental Review 

The FAA has determined that this 

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1E, ‘‘Environmental 

Impacts: Policies and Procedures,’’ 

paragraph 311a. This airspace action is 

not expected to cause any potentially 

significant environmental impacts, and 

no extraordinary circumstances exist 

that warrant preparation of an 

environmental assessment.

SUPPLEMENTARY INFORMATION: 

History 

On March 26, 2013, the FAA 

published in the Federal Register a

Ashland, WI (78 FR 18271). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on this proposal to 

the FAA. No comments were received. 

The Rule 

The FAA is amending Title 14, Code 

of Federal Regulations (14 CFR) part 71 

by modifying VOR Federal airway V– 

345 in the vicinity of Ashland, WI, due 

to the scheduled decommissioning of 

the Ashland, WI, VOR/DME. This action 

removes the airway segment between 

the Hayward, WI, VOR/DME and the 

Ashland, WI, VOR/DME navigation 

aids. 

VOR Federal airways are published in 

paragraph 6010(a) of FAA Order 

7400.9W signed August 8, 2012 and 

effective September 15, 2012, which is 

incorporated by reference in 14 CFR 

71.1. The VOR Federal airway listed in 

this document would be subsequently 

published in the Order. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are
