SUPPLEMENTARY INFORMATION:
Background
On April 20, 2010, the FAA published Special Condition No. 23-245-
SC for the Cirrus Design Corporation new model SF50. The model SF50 is
a 7-seat (5 adults and 2 children), pressurized, retractable gear,
carbon composite, airplane with one turbofan engine mounted partially
in the upper aft fuselage.
The single turbofan engine is mounted on the upper aft fuselage,
not in the pilot's line of site. Upper aft fuselage mounted engine
installations, along with the need to protect such installed engines
from fires, were not envisioned in the development of the part 23
normal category regulations.
The model SF50 certification project was granted an extension on
September 19, 2011. Amendment 23-62 (76 FR 75736), published December
2, 2011, incorporated Special Condition No. 23-245-SC. On December 11,
2012, Cirrus Design Corporation elected to adjust the model SF50
certification basis to 14 CFR part 23, Amendment 62.
Reason for Withdrawal
The FAA is withdrawing Special Condition No. 23-245-SC because
Cirrus 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 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 5, 2013.

Small Airplane Directorate, Aircraft Certification Service.
