SUPPLEMENTARY INFORMATION: 

Background 

On August 18, 2010, the FAA 

published Special Condition No. 23– 

248–SC for the Cirrus Design 

Corporation new model SF50 ‘‘Vision’’ 

Jet. The SF50 is a low-wing, five-plustwo-place (2 children), single-engine 

turbofan-powered aircraft. It 

incorporates an Electronic Flight 

Information System (EFIS), pressurized 

cabin, retractable gear, and a V-tail. The 

turbofan engine is mounted on the 

upper fuselage/tail cone along the 

aircraft centerline. It is constructed 

largely of carbon and fiberglass 

composite materials. Like other Cirrus 

products, the SF50 includes a 

ballistically deployed airframe 

parachute. 

The model SF50 has a maximum 

operating altitude of 28,000 feet, where 

it cruises at speeds up to 300 Knots True 

Air Speed (KTAS). Its MMO will not 

exceed 0.62 Mach. The maximum 

takeoff weight will be at or below 6000 

pounds with a range at economy cruise 

of roughly 1000 nm. Cirrus intends for 

the model SF50 to be certified for 

single-pilot operations under 14 CFR 

part 91 and 14 CFR part 135 operating 

rules. The following operating 

conditions will be included: 

• Day and Night VFR 

• IFR 

• Flight Into Known Icing 

Discussion 

Before Amendment 3–4, Section 3.19 

of Civil Air Regulation (CAR) part 3 

required service testing of all airplanes 

type certificated on or after May 15, 

1947. The purpose of the testing was to 

‘‘ascertain whether there is reasonable 

assurance that the airplane, its 

components, and equipment are 

reliable, and function properly.’’ 

Amendment 3–4 to CAR part 3 

became effective January 15, 1951, and 

deleted the service test requirements in 

Section 3.19 for airplanes of 6,000 

pounds maximum weight or less. The 

introductory text published in 

Amendment 3–4 explained that most of 

the significant changes in the 

amendment stemmed from ‘‘the desire 

for simplification of the rules in this 

part with respect to the smaller 

airplanes, specifically those of 6,000 

pounds maximum weight or less, which 

would be expected to be used mainly as 

personal airplanes.’’ The introductory 

material also stated the service test 

requirement was removed for airplanes 

of 6,000 pounds maximum weight or 

less because ‘‘experience seems to 

indicate that this rule imposes a burden 

upon the manufacturers not 

commensurate with the safety gained.’’ 

The requirement for Function and 

Reliability (F&R) testing, and the 

exception for airplanes of 6,000 pounds 

or less maximum weight, is now found 

in 14 CFR part 21, section 21.35(b)(2). 

The decision to exempt airplanes of 

6,000 pounds maximum weight or less 

from F&R testing was based on the state 

of technology envisioned in 1951. At 

that time, airplanes of 6,000 pounds 

maximum weight or less were expected 

to be used mainly as personal airplanes. 

They used simple, ‘‘stand-alone’’ 

systems whose failure was more likely 

to be an inconvenience than an 

accident. The situation is different 

today. Technological advances allow 

airplanes weighing less than 6,000 

pounds to be more complex and 

integrated than some transport 

airplanes. New part 23 airplanes can 

incorporate sophisticated equipment not 

previously used in a part 23 aircraft. 

Additionally, part 23 airplanes are being 

used for business and commercial 

transportation. They should no longer 

be envisioned mainly as personal 

airplanes. Therefore, a special condition 

to require F&R testing for airplanes 

weighing 6,000 pounds or less is needed 

where the level of sophistication is 

beyond evaluating failures by 

inspection. 

The model SF50 certification project 

was granted an extension on September 

19, 2011. 14 CFR part 21, Amendment 

95, published in the Federal Register 

(76 FR 64229) on October 18, 2011, 

incorporated Special Condition No. 23– 

248–SC. On December 11, 2012, Cirrus 

Design Corporation elected to adjust the 

model SF50 certification basis to 

Amendment 21–95. 

Reason for Withdrawal 

The FAA is withdrawing Special 

Condition No. 23–248–SC because 

Cirrus elected to revise the model SF50 

certification basis to Amendment 21–95. 

The authority citation for this Special 

Condition withdrawal is 49 U.S.C. 

106(g), 40113 and 44701; 14 CFR 21.16 

and 21.17; and 14 CFR 11.38 and 11.19. 

Conclusion 

Withdrawal of this special condition 

does not preclude the FAA from issuing 

another notice on the subject matter in 

the future or committing the agency to 

any future course of action. 

Issued in Kansas City, Missouri on June 7, 

2013.
