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. Flight Envelope Protection: Normal 

Load Factor (g) Limiting. 

To meet the intent of adequate 

maneuverability and controllability 

required by § 25.143(a), and in addition 

to the requirements of § 25.143(a) and in 

the absence of other limiting factors, the 

following special conditions are issued 

based on § 25.333(b): 

(a) The positive limiting load factor 

must not be less than: 

(1) 2.5g for the normal state of the 

electronic flight control system with the 

high lift devices retracted. 

(2) 2.0g for the normal state of the 

electronic flight control system with the 

high lift devices extended. 

(b) The negative limiting load factor 

must be equal to or more negative than: 

(1) Minus 1.0g for the normal state of 

the electronic flight control system with 

the high lift devices retracted. 

(2) 0.0g for the normal state of the 

electronic flight control system with 

high lift devices extended. 

(c) Maximum reachable positive load 

factor wings level may be limited by the 

characteristics of the electronic flight 

control system or flight envelope 

protections (other than load factor 

protection) provided that: 

(1) The required values are readily 

achievable in turns, and 

(2) That wings level pitch up is 

satisfactory. 

(d) Maximum achievable negative 

load factor may be limited by the 

characteristics of the electronic flight 

control system or flight envelope 

protections (other than load factor 

protection) provided that: 

(1) Pitch down responsiveness is 

satisfactory, and 

(2) From level flight, 0g is readily 

achievable, or alternatively, a 

satisfactory trajectory change is readily 

achievable at operational speeds. For 

the FAA to consider a trajectory change 

as satisfactory, the applicant should 

propose and justify a pitch rate that 

provides sufficient maneuvering 

capability in the most critical scenarios. 

(e) Compliance demonstration with 

the above requirements may be 

performed without ice accretion on the 

airframe. 

(f) These special conditions do not 

impose an upper bound for the normal 

load factor limit, nor does it require that 

the limiter exist. If the limit is set at a 

value beyond the structural design limit 

maneuvering load factor n of 

§§ 25.333(b), 25.337(b), 25.337(c), there 

should be a very obvious positive tactile 

feel built into the controller so that it 

serves as a deterrent to inadvertently 

exceeding the structural limit.

Stage 3 Helicopter Noise Certification 

Standards; Correction 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; correction. 

SUMMARY: The Federal Aviation 

Administration (FAA) published in the 

Federal Register of March 4, 2014 a 

document adopting more stringent noise 

certification standards for helicopters 

that are certificated in the United States 

(U.S.). Inadvertently the incorrect 

amendment number was assigned. This 

document corrects the amendment 

number cited in the heading of the final 

rule. 

DATES: This correction is effective April 

14, 2014.

SUPPLEMENTARY INFORMATION: The FAA 

published a document in the Federal 

Register of March 4, 2014 (79 FR 12040) 

as Amendment Number 36–29. In FR 

Doc. 2014–04479, Amdt. No. 36–29 is 

incorrect. This document corrects the 

amendment number published on 

March 4, 2014. 

In FR Doc. 2014–04479, beginning on 

page 12040 in the Federal Register of 

March 4, 2014, make the following 

correction: 

On page 12040, in the second column 

heading, correct the amendment number 

from ‘‘36–29’’ to ‘‘36–30’’.

Modification of Area Navigation 

(RNAV) Route Q–20, TX 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action modifies RNAV 

route Q–20 by relocating the FUSCO 

waypoint (WP) southwest to match the 

intersection of Jet routes J–15 and J–183. 

This action enhances the safe and 

efficient management of aircraft within 

the National Airspace System. 

DATES: Effective Date: 0901 UTC, July 

24, 2014. 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 

The FAA published in the Federal 

Register a notice of proposed 

rulemaking (NPRM) to amend Q–20 by 

moving the FUSCO WP to match the 

intersection of Jet Routes J–15 and J– 

183, and re-designate the WP as a fix (78 

FR 70900, November 27, 2013). 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received.
