SUPPLEMENTARY INFORMATION:

Background

    On September 9, 2008, Cirrus Design Corporation applied for a type 
certificate for their new model SF50 aircraft. Under the provisions of 
14 CFR part 21, Sec.  21.17, Cirrus Design Corporation must show that 
the model SF50 meets the applicable provisions of part 23, as amended 
by amendments 23-1 through 23-59.
    On April 20, 2010, the FAA published Special Condition No. 23-246-
SC for the Cirrus Design Corporation model SF50 airplane. The Cirrus 
SF50 is a low-wing, five-plus-two-place (2 children), single-engine 
turbofan-powered aircraft. The airplane engine is controlled by an 
Electronic Engine Control (EEC), also known as a Full Authority Digital 
Engine Control (FADEC).
    On December 11, 2012 Cirrus Design Corporation elected to adjust 
the certification basis of the SF50 to include 14 CFR part 23 through 
amendment 62. Special Condition No. 23-246-SC is therefore being 
withdrawn. It no longer reflects the appropriate part 23 amendment 
level of the aircraft and the basic Special Condition requirement for 
EEC equipped aircraft has been revised.

Reason for Withdrawal

    The FAA is withdrawing Special Condition No. 23-246-SC because 
Cirrus Design Corporation elected to revise the model SF50 
certification basis to amendment 23-62.
    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 document on the subject matter in the future or 
committing the agency to any future course of action.

    Issued in Kansas City, Missouri on May 11, 2015.

Manager, Small Airplane Directorate, Aircraft Certification Service.
