SUPPLEMENTARY INFORMATION: 

Background

    On November 14, 2014, the Federal Register published a Final 
Special Conditions, Request for Comment, Docket No. FAA-2014-0564, 
Special Conditions No. 25-573-SC (79 FR 68107), for the Dassault Model 
Falcon 900EX airplane on the subject of electronic system-security 
protection from unauthorized external access.
    Note that the original publication of the special conditions 
incorrectly indicates, in the document header, Special Conditions No. 
25-XXX-SC. This withdrawal document reflects the correct special 
conditions number.

Reason for Withdrawal

    The FAA withdraws Special Conditions No. 25-573-SC after 
considering comments Dassault submitted during the public-comment 
period. Dassault's comment, in pertinent part, is as follows, with 
minor edits for clarity:

    The Proposed Special Conditions indicate that they are 
applicable to the ``new Model 900EX airplane.'' This statement is 
factually wrong. Dassault believes that these special conditions 
were intended for a Dassault Aviation Services (DAS) supplemental 
type certificate (STC) regarding the replacement of the display unit 
on the Dassault Model 900EX airplane (FAA project number ST07490NY-
T). Furthermore, previous discussions between the FAA and DAS led to 
the conclusion that the STC for the replacement of the display unit 
on the Dassault Model 900EX airplane (FAA project number ST07490NY-
T) did not contain any changes involving the connectivity to the 
avionics system. Accordingly, there is no specific vulnerability to 
the systems due to the replacement of the display unit. Therefore, 
there was no novelty in the STC that would require the issuance of 
the proposed special conditions. The STC was approved in [2014] 
(ST03371NY) without any special conditions on this subject.
    In view of the foregoing, Dassault Aviation respectfully 
requests that the FAA rescind [Special Conditions No. 25-573-SC].

    The FAA agrees with Dassault's comments and withdraws the special 
conditions. These special conditions are not included in, and are not a 
part of, the type certificate for the Dassault Model Falcon 900EX 
airplane.

Conclusion

    This action affects only the special conditions indicated above for 
the Dassault Model Falcon 900EX airplane.
    In light of Dassault's comments, the FAA agrees that these special 
conditions are not necessary, and that withdrawal of the special 
conditions is not detrimental to the operation of the airplane. 
Accordingly, pursuant to the authority delegated to me by the 
Administrator, Special Conditions No. 25-573-SC is withdrawn.
    The FAA finds that good cause exists to make this withdrawal of 
special conditions effective upon issuance.

    Issued in Renton, Washington, on April 7, 2017.

Assistant Manager, Transport Airplane Directorate, Aircraft 
Certification Service.
