Conditions No. 25–617–SC] 

Special Conditions: Gulfstream 

Aerospace Corporation Model GVII– 

G500 Airplanes, Design Roll Maneuver 

Requirement 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final special conditions; request 

for comments. 

SUMMARY: These special conditions are 

issued for the Gulfstream Aerospace 

Corporation (Gulfstream) Model GVII– 

G500 airplane. This airplane will have 

a novel or unusual design feature when 

compared to the state of technology 

envisioned in the airworthiness 

standards for transport category 

airplanes. This design feature is 

electronic flight controls that affect 

maneuvering. The applicable 

airworthiness regulations do not contain 

adequate or appropriate safety standards 

for this design feature. These 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.

SUPPLEMENTARY INFORMATION The FAA 

has determined that notice of, and 

opportunity for prior public comment 

on, these special conditions is 

impracticable because these procedures 

would significantly delay issuance of 

the design approval and thus delivery of 

the affected airplane. 

In addition, the substance of these 

special conditions has been subject to 

the public comment process in several 

prior instances with no substantive 

comments received. The FAA therefore 

finds that good cause exists for making 

these special conditions effective upon 

publication in the Federal Register. 

Comments Invited 

We invite interested people to take 

part in this rulemaking by sending 

written comments, data, or views. The 

most helpful comments reference a 

specific portion of the special 

conditions, explain the reason for any 

recommended change, and include 

supporting data. 

We will consider all comments we 

receive by the closing date for 

comments. We may change these special 

conditions based on the comments we 

receive. 

Background 

On March 29, 2012, Gulfstream 

Aerospace Corporation applied for a 

type certificate for their new Model 

GVII–G500 series airplane. The Model 

GVII–G500 series airplane will be a 

business jet capable of accommodating 

up to 19 passengers. It will incorporate 

a low, swept-wing design with winglets 

and a T-tail. The powerplant will 

consist of two aft-fuselage-mounted 

Pratt & Whitney turbofan engines. 

Type Certification Basis 

Under Title 14, Code of Federal 

Regulations (14 CFR) 21.17, Gulfstream 

must show that the Model GVII–G500 

series airplane meets the applicable 

provisions of 14 CFR part 25, as 

amended by Amendments 25–1 through 

25–129. 

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 Model GVII–G500 series airplane 

because of a novel or unusual design 

feature, special conditions are 

prescribed under the provisions of 

§ 21.16. 

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 or similar novel 

or unusual design feature, the special 

conditions would also apply to the other 

model under § 21.101. 

In addition to the applicable 

airworthiness regulations and special 

conditions, Model GVII–G500 series 

airplanes must comply with the fuelvent and exhaust-emission requirements 

of 14 CFR part 34, and the noiseVerDate Sep<11>2014 13:24 Apr 20, 2016 Jkt 238001 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 E:\FR\FM\21APR1.SGM 21APR1

23422 Federal Register / Vol. 81, No. 77 / Thursday, April 21, 2016 / Rules and Regulations 

certification requirements of 14 CFR 

part 36. The FAA must issue a finding 

of regulatory adequacy under § 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). 

Novel or Unusual Design Features 

The Model GVII–G500 series airplane 

will incorporate the following novel or 

unusual design feature: An electronic 

flight-control system that provides 

control of the airplane through pilot 

inputs to the flight computer. 

Current 14 CFR part 25 airworthiness 

regulations account for control laws for 

which aileron deflection is proportional 

to control-stick deflection. The 

regulations do not address 

nonlinearities or other effects on aileron 

actuation that electronic flight controls 

may cause. Because this type of system 

may affect flight loads, and therefore the 

structural capability of the airplane, 

specific regulations are needed to 

address these effects. 

Discussion 

The current design roll maneuver 

requirement for structural loads in 14 

CFR part 25 is inadequate for addressing 

airplanes with electronic flight controls 

that affect maneuvering. These special 

conditions adjust the current roll 

maneuver requirement, § 25.349(a), to 

take into account the effects of an 

electronic flight control system. 

These special conditions differ from 

current requirements in that they 

require roll maneuvers to result from 

defined movements of the flightdeck 

roll control, as opposed to defined 

aileron deflections. Also, the special 

conditions require an additional load 

condition at VA, in which the flightdeck 

roll control is returned to neutral 

following the initial roll input. 

These special conditions are limited 

to the roll axis only. Special conditions 

are no longer needed for the yaw axis 

because § 25.351 was revised at 

Amendment 25–91 to account for the 

effects of an electronic flight-control 

system. 

These 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. 

Applicability 

As discussed above, these special 

conditions are applicable to the 

Gulfstream Model GVII–G500 airplane. 

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 feature, 

these special conditions would apply to 

that model as well. 

Conclusion 

This action affects only a certain 

novel or unusual design feature on one 

model series of airplanes. It is not a rule 

of general applicability. 

The substance of these special 

conditions has been subjected to the 

notice and comment period in several 

prior instances and has been derived 

without substantive change from those 

previously issued. It is unlikely that 

prior public comment would result in a 

significant change from the substance 

contained herein. Therefore, because a 

delay would significantly affect the 

certification of the airplane, the FAA 

has determined that prior public notice 

and comment are unnecessary and 

impracticable, and good cause exists for 

adopting these special conditions upon 

publication in the Federal Register. 

The FAA is requesting comments to 

allow interested persons to submit 

views that may not have been submitted 

in response to the prior opportunities 

for comment described above.

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 Gulfstream Model 

GVII–G500 airplanes. 

The following conditions, speeds, and 

flightdeck roll control motions (except 

as the motions may be limited by pilot 

effort) must be considered in 

combination with an airplane load 

factor of zero and of two-thirds of the 

positive maneuvering factor used in 

design. In determining the resulting 

control surface deflections, the torsional 

flexibility of the wing must be 

considered in accordance with 

§ 25.301(b): 

1. Conditions corresponding to steady 

rolling velocities must be investigated. 

In addition, conditions corresponding to 

maximum angular acceleration must be 

investigated for airplanes with engines 

or other weight concentrations outboard 

of the fuselage. For the angular 

acceleration conditions, zero rolling 

velocity may be assumed in the absence 

of a rational time history investigation 

of the maneuver. 

2. At VA, sudden movement of the 

flightdeck roll control up to the limit is 

assumed. The position of the flightdeck 

roll control must be maintained until a 

steady roll rate is achieved and then 

must be returned suddenly to the 

neutral position. 

3. At VC, the flightdeck roll control 

must be moved suddenly and 

maintained so as to achieve a roll rate 

not less than that obtained in special 

condition 2. 

4. At VD, the flightdeck roll control 

must be moved suddenly and 

maintained so as to achieve a roll rate 

not less than one-third of that obtained 

in special condition 2. 

Issued in Renton, Washington, on April 14,
