architecture and a full digital flight 

control system which provides 

comprehensive flight envelope 

protections. 

Discussion 

The applicable airworthiness 

regulation in this instance is 14 CFR 

§ 25.143. The purpose of § 25.143 is to 

verify that any operational maneuvers 

conducted within the operational 

envelope can be accomplished smoothly 

with average piloting skill and without 

exceeding any structural limits. The 

pilot should be able to predict the 

airplane response to any control input. 

During the course of the flight test 

program, the pilot determines 

compliance with § 25.143 through 

primarily qualitative methods. During 

flight test, the pilot should evaluate all 

of the following: 

• The interface between each 

protection function, 

• Transitions from one mode to 

another, 

• The aircraft response to intentional 

dynamic maneuvering, whenever 

applicable, through dedicated 

maneuvers, 

• General controllability assessment, 

• High speed characteristics, and 

• High angle-of-attack. 

Section § 25.143, however, does not 

adequately ensure that the novel or 

unusual features of the Model EMB–550 

airplane will have a level of safety 

equivalent to that of existing standards. 

This special condition is therefore 

required to accommodate the the flightenvelope-limiting systems in the Model 

EMB–550 airplane. The additional 

safety standards in this special 

condition will ensure a level of safety 

equivalent to that of existing standards. 

Discussion of Comments 

Notice of proposed special conditions 

number 25–19–SC for the Embraer S.A. 

Model EMB–550 airplanes was 

published in the Federal Register on 

January 24, 2013 (78 FR 5148). No 

comments were received, and the 

special conditions are adopted as 

proposed. 

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. 

List of Subjects in 14 CFR Part 25 

Aircraft, Aviation safety, Reporting 

and recordkeeping requirements. 

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 Embraer S.A. Model EMB–550 

airplanes. 

1. General Limiting Requirements: 

a. Onset characteristics of each 

envelope protection feature must be 

smooth, appropriate to the phase of 

flight and type of maneuver, and not in 

conflict with the ability of the pilot to 

satisfactorily change airplane flight 

path, speed, or attitude as needed. 

b. Limit values of protected flight 

parameters (and if applicable, associated 

warning thresholds) must be compatible 

with the following: 

i. Airplane structural limits, 

ii. Required safe and controllable 

maneuvering of the airplane, and 

iii. Margins to critical conditions. 

Unsafe flight characteristics/conditions 

must not result if dynamic 

maneuvering, airframe and system 

tolerances (both manufacturing and inservice), and non-steady atmospheric 

conditions, in any appropriate 

combination and phase of flight, can 

produce a limited flight parameter 

beyond the nominal design limit value. 

c. The airplane must be responsive to 

intentional dynamic maneuvering to 

within a suitable range of the parameter 

limit. Dynamic characteristics such as 

damping and overshoot must also be 

appropriate for the flight maneuver and 

limit parameter in question. 

d. When simultaneous envelope 

limiting is engaged, adverse coupling or 

adverse priority must not result. 

2. Failure States: Electronic flight 

control system failures (including 

sensor) must not result in a condition 

where a parameter is limited to such a 

reduced value that safe and controllable 

maneuvering is no longer available. The 

crew must be alerted by suitable means 

if any change in envelope limiting or 

maneuverability is produced by single 

or multiple failures of the electronic 

flight control system not shown to be 

extremely improbable.

History 

Federal Register document FAA 

2012–0821, Airspace Docket No. 12– 

ASW–8, establishes Class E Airspace at 

Chase Field Industrial Airport, Beeville, 

TX (78 FR 18801, March 28, 2013). 

Subsequent to publication, the FAA 

found that existing controlled airspace 

already is charted for another airport at 

Beeville, TX, with the same descriptor. 

Since there can only be one Beeville, 

TX, the title and airspace designation 

for Chase Field Industrial Airport is 

changed from Beeville, TX, to BeevilleChase Field, TX. This correction is 

related to published aeronautical charts 

that are essential to the user, and 

provide for the safe and efficient use of 

the navigable airspace. Class E airspace 

designations are published in paragraph 

6005 of FAA Order 7400.9W dated

reference in 14 CFR 71.1. The Class E 

airspace designation listed in this 

document will be published 

subsequently in the Order.

Drawbridge Operation Regulation; 

Cumberland River, Nashville, TN 

AGENCY: Coast Guard, DHS. 

ACTION: Notice of deviation from 

drawbridge regulation. 

SUMMARY: The Coast Guard has issued a 

temporary deviation from the operating 

schedule that governs the Louisville and 

Nashville Railroad Drawbridge across 

the Cumberland River, mile 190.4, at 

Nashville, Tennessee. The deviation is 

necessary to allow the bridge owner 

time to perform preventive maintenance 

that is essential to the continued safe 

operation of the drawbridge. This 

deviation allows the bridge to remain in 

the closed-to-navigation position while 

a worn gear and shaft assembly are 

replaced. 

DATES: This deviation is effective from 

8 a.m., May 28, 2013 to 6 p.m., May 29, 

2013. 

ADDRESSES: The docket for this 

deviation, [USCG–2013–0370] is

SUPPLEMENTARY INFORMATION: The CSX 

Transportation, Inc. requested a 

temporary deviation for the Louisville 

and Nashville Railroad Drawbridge, 

across the Cumberland River, mile 

190.4, at Nashville, Tennessee to remain 

in the closed-to-navigation position 

while a worn gear and shaft assembly 

are replaced. The closure period will 

start at 8 a.m., May 28, 2013 to 6 p.m., 

May 29, 2013. 

Once the worn gear and shaft 

assembly are removed, the swing span 

will not be able to open, even for 

emergencies, until the replacement of 

the gear and shaft assembly is installed. 

The Louisville and Nashville Railroad 

Drawbridge currently operates in 

accordance with 33 CFR 117.5, which 

states the general requirement that 

drawbridges shall open promptly and 

fully for the passage of vessels when a 

request to open is given in accordance 

with the subpart. In order to facilitate 

the needed bridge work, the drawbridge 

must be kept in the closed-to-navigation 

position. 

There are no alternate routes for 

vessels transiting this section of the 

Cumberland River. 

The Louisville and Nashville Railroad 

Drawbridge, in the closed-to-navigation 

position, provides a vertical clearance of 

47 feet above normal pool. Navigation 

on the waterway consists primarily of 

commercial tows and recreational 

watercraft. This temporary deviation has 

been coordinated with the waterway 

users. No objections were received. 

In accordance with 33 CFR 117.35(e), 

the drawbridge must return to its regular 

operating schedule immediately at the 

end of the designated period of this 

temporary deviation. This deviation 

from the operating regulations is 

authorized under 33 CFR 117.35. 

Dated: May 8, 2013.
