[Docket No. NM446 Special Conditions No. 

25–11–05–SC] 

Special Conditions: Gulfstream Model 

GVI Airplane; Electronic Flight Control 

System: Control Surface Position 

Awareness 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed special 

conditions. 

SUMMARY: This action proposes special 

conditions for the Gulfstream GVI 

airplane. This airplane will have novel 

or unusual design features when 

compared to the state of technology 

envisioned in the airworthiness 

standards for transport category 

airplanes. These design features include 

an electronic flight control system. The 

applicable airworthiness regulations do 

not contain adequate or appropriate 

safety standards for these design 

features. These proposed special 

conditions contain the additional safety 

standards that the Administrator 

considers necessary to establish a level 

of safety equivalent to that established 

by the existing airworthiness standards. 

DATES: We must receive your comments 

by April 4, 2011. 

ADDRESSES: You must mail two copies 

of your comments to: Federal Aviation 

Administration, Transport Airplane 

Directorate, Attn: Rules Docket (ANM– 

113), Docket No. NM446, 1601 Lind 

Avenue, SW., Renton, Washington, 

98057–3356. You may deliver two 

copies to the Transport Airplane 

Directorate at the above address. You 

must mark your comments: Docket No.

Background 

On March 29, 2005, Gulfstream 

Aerospace Corporation (hereafter 

referred to as ‘‘Gulfstream’’) applied for 

an FAA type certificate for its new 

Gulfstream Model GVI passenger 

airplane. Gulfstream later applied for, 

and was granted, an extension of time 

for the type certificate, which changed 

the effective application date to 

September 28, 2006. The Gulfstream 

Model GVI airplane will be an all-new, 

two-engine jet transport airplane with 

an executive cabin interior. The 

maximum takeoff weight will be 99,600 

pounds, with a maximum passenger 

count of 19 passengers. 

Type Certification Basis 

Under provisions of Title 14, Code of 

Federal Regulations (14 CFR) 21.17, 

Gulfstream must show that the 

Gulfstream Model GVI airplane 

(hereafter referred to as ‘‘the GVI’’) meets 

the applicable provisions of 14 CFR part 

25, as amended by Amendments 25–1 

through 25–119, 25–122, and 25–124. If 

the Administrator finds that the 

applicable airworthiness regulations 

(i.e., 14 CFR part 25) do not contain 

adequate or appropriate safety standards 

for the GVI because of a novel or 

unusual design feature, special 

conditions are prescribed under the 

provisions of § 21.16. 

In addition to complying with the 

applicable airworthiness regulations 

and special conditions, the GVI 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. The 

FAA must also issue a finding of 

regulatory adequacy pursuant to section 

611 of Public Law 92–574, the ‘‘Noise 

Control Act of 1972.’’ 

The FAA issues special conditions, as 

defined in 14 CFR 11.19, in accordance 

with § 11.38, and they become part of 

the type certification basis under 

§ 21.17(a)(2). 

Special conditions are initially 

applicable to the model for which they 

are issued. Should the type certificate 

for that model be amended later to 

include any other model that 

incorporates the same novel or unusual 

design features, the special conditions 

would also apply to the other model 

under provisions of § 21.101. 

Novel or Unusual Design Features 

The GVI has an electronic flight 

control system and no direct coupling 

from the cockpit controller to the 

control surface, so the pilot may not be 

aware of the actual surface position 

utilized to fulfill the requested 

command. Some unusual flight 

conditions, such as those arising from 

atmospheric conditions, aircraft 

malfunctions, or engine failures, may 

result in full or near-full control surface 

deflection. Unless the flightcrew is 

made aware of excessive deflection or 

impending control surface limiting, 

piloted or auto-flight system control of 

the airplane might be inadvertently 

continued to a point that could cause a 

loss of aircraft control or other unsafe

stability or performance characteristic. 

Because electronic flight control system 

technology has outpaced existing 

regulations, a special condition is 

proposed to ensure control surface 

position awareness by the flightcrew. 

Discussion of Proposed Special 

Condition 

This proposed special condition 

would require that suitable flight 

control position annunciation be 

provided to the flightcrew when a flight 

condition exists in which near-full 

surface authority (not crewcommanded) is being utilized. The 

suitability of such an annunciation must 

take into account that some pilotdemanded maneuvers, such as a rapid 

roll, are necessarily associated with 

intended full performance, and which 

may saturate the control surface. Simple 

alerting systems which would 

annunciate either intended or 

unexpected control-limiting situations 

must be properly balanced between 

providing necessary crew awareness 

and avoiding undesirable nuisance 

warnings. 

This proposed special condition 

would establish a level of safety 

equivalent to that provided by a 

conventional flight control system and 

that contemplated in existing 

regulations. 

Applicability 

As discussed above, this proposed 

special condition is applicable to the 

GVI. Should Gulfstream apply at a later 

date for a change to the type certificate 

to include another model incorporating 

the same novel or unusual design 

features, this proposed special condition 

would apply to that model as well. 

Conclusion 

This action affects only certain novel 

or unusual design features of the GVI. 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 Proposed Special Condition 

Accordingly, the Federal Aviation 

Administration (FAA) proposes the 

following special condition as part of 

the type certification basis for the GVI 

airplanes. 

In addition to compliance with 

§§ 25.143, 25.671, 25.672, and 25.1322, 

the following special condition applies: 

When a flight condition exists where, 

without being commanded by the 

flightcrew, control surfaces are coming 

so close to their limits that return to the 

normal flight envelope and/or 

continuation of safe flight requires a 

specific flightcrew member action, a 

suitable flight control position 

annunciation must be provided to the 

flightcrew, unless other existing 

indications are found adequate or 

sufficient to prompt that action. 

Note: The term ‘‘suitable’’ also indicates an 

appropriate balance between necessary 

operation and nuisance factors.

[Docket No. FAA–2011–0023; Airspace 

Docket No. 11–ANM–2] 

Proposed Amendment of Class D and 

Class E Airspace; Idaho Falls, ID 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This action proposes to 

amend the Class D and Class E airspace 

areas at Idaho Falls, ID, by changing the 

name of the airport to Idaho Falls 

Regional Airport, and adjusting the 

geographic coordinates of the airport. 

This action also would add additional 

Class E airspace necessary to 

accommodate aircraft using new Area 

Navigation (RNAV) Required Navigation 

Performance (RNP) standard instrument 

approach procedures at the airport. This 

action would enhance the safety and 

management of aircraft operations at the 

airport. 

DATES: Comments must be received on 

or before April 4, 2011.
